Earth's Atmosphere

What is earth’s atmosphere, a jacket for the planet.

Earth is a great planet to live on because it has a wonderful atmosphere around it. This jacket of gases does a lot for us. It keeps us warm, it gives us oxygen to breathe, and it’s where our weather happens.

The atmosphere surrounds our planet like the peel of an orange. But it’s not the same everywhere. It has different layers with different qualities.

One atmosphere, many layers

Earth’s atmosphere has six different layers. They go from the ground all the way to outer space. To learn more about each layer of the atmosphere, click the images below.

(This is only part of the exosphere. It's actually 12 times bigger than this!)

Layers of Earth's Atmosphere

Earth's atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space.

The layers of the atmosphere: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

• Troposphere

The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere .

• Stratosphere

The next layer up is called the stratosphere . The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. The jet stream flows near the border between the troposphere and the stratosphere.

Above the stratosphere is the mesosphere . It extends upward to a height of about 85 km (53 miles) above our planet. Most meteors burn up in the mesosphere. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer. The air in the mesosphere is far too thin to breathe (the air pressure at the bottom of the layer is well below 1% of the pressure at sea level and continues dropping as you go higher).

• Thermosphere

The layer of very rare air above the mesosphere is called the thermosphere . High-energy X-rays and UV radiation from the Sun are absorbed in the thermosphere, raising its temperature to hundreds or at times thousands of degrees. However, the air in this layer is so thin that it would feel freezing cold to us! In many ways, the thermosphere is more like outer space than a part of the atmosphere. In fact, the approximate boundary between our atmosphere and outer space, known as the Kármán Line, is in the thermosphere, at an altitude of about 100 km. Many satellites actually orbit Earth within the thermosphere! Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher.

Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the exosphere to be the actual "final frontier" of Earth's gaseous envelope. As you might imagine, the "air" in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. There is no clear-cut upper boundary where the exosphere finally fades away into space. Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth. The latter value is about halfway to the Moon!

The ionosphere is not a distinct layer like the others mentioned above. Instead, the ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules. The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name and endowing this region with some special properties. The aurora, or Northern Lights and Southern Lights, occur in the parts of the thermosphere that correspond to layers of the ionosphere.

One of the main components of Earth’s interdependent physical systems is the atmosphere. An atmosphere is made of the layers of gases surrounding a planet or other celestial body. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.

Importance of atmosphere

The atmosphere plays a very important role in making the planet livable. It protects the life on Earth from the dangerous rays of Sun . Atmosphere traps heat, and make the planet a comfortable place to live. Atmosphere is considered to be vital in maintaining the water cycle. It helps to facilitate the clouds formation that remains suspended till they are pour down as snow, hail or rain due to heaviness. Besides these, there are several more benefits of atmosphere. Let us know more about it in detail.

About the atmosphere

The atmosphere on Earth is either transparent or reflective, on the basis of the wavelength of the rays to which it is exposed. Due to which, the atmosphere gets little amount of direct heat via solar radiation.

This solar energy either reflects into space or passes through the atmosphere without absorption of its energy. Most of the energy is reflected via chemical compounds, and clouds like the ozone layer. Only 54% of the total energy of sun succeed to pass through the atmosphere to finally reach the planet’s surface.

Benefits of atmosphere

Protects from the harmful rays of sun: Atmosphere acts as a shield that protects the planet from the harmful ultra violet rays of the sun and cosmic rays. These radiations cause destruction to eyes and skin of whoever gets exposed to it. The ozone layer in the atmosphere is responsible for saving the planet from the destructive rays of the sun. This layer reflects the ultra violet rays of the run so that it doesn’t reach the earth surface.

Thick sheets of molecular gases present in the atmosphere have the ability to absorb gamma rays, x-rays, and cosmic rays, thereby preventing such energetic particles to strike living things and cause genetic damage and mutations. A solar flare can increase the damage output of the atmosphere and the sun that helps in blocking a lot of the harmful effects.

Maintains constant temperature: The congenial temperature is very important for the life to be present on the Earth. Atmosphere helps in maintaining constant temperature on the earth to support the life of people. It also safeguards the planet from small sized meteors. The Earth’s atmosphere comprises of nitrogen oxide and a few more gases that helps in supporting the life of people on the earth.

On Earth, molecules present in the atmosphere soaks the energy of the sun. In this way, it spreads the warmness across the entire planet. These molecules trap reflected sun’s energy from the surface. In this way, it prevents the planet from becoming severely cold.

Aids in combustion: Atmosphere helps in facilitating combustion. The oxygen present in the atmosphere is responsible to accomplish the task. If there had been no atmosphere, then combustion would have not been possible.

Saves the life on Earth from getting endangered: Without the defensive layer of gases that forms up the atmosphere on Earth, the stringent state of the solar system would have left made the planet as a lifeless and barren land like the moon. The atmosphere on Earth safeguards the population by absorbing dangerous solar rays and thereby providing the much-needed warmth to the inhabitants.

Along with it, the Earth’s atmosphere is composed of the carbon dioxide, and oxygen which is needed by the living beings to survive. By trapping the sun’s energy, it keeps a lot of destructive elements of space at bay.

Physical Protection: The solar system is full of small particles and debris that remains there after creation of planets or crashes in the asteroid belt. When these particles come in contact with the Earth’s atmosphere, then the resultant friction destroys them before they result in any destruction.

Water and Weather: The atmosphere serves as a medium for the displacement of water. Water vapor evaporates out of the ocean, condenses and falls as rain. This provides moisture to dry zones of the continent. The atmosphere on Earth has 12,900 cu. km. worth of water. In the absence of atmosphere, all the water would have evaporated away into space, leaving behind the frozen planet.

The Greenhouse Effect: The atmosphere on Earth comprise of several chemicals. A majority of the infrared rays released by the warm water surface can’t makes its way into the space. In place of it, the radiation gets absorbed or reflected by compounds called as greenhouse gasses.

Absorption of the infrared rays by chemical compounds heats up the temperature of the atmosphere. This energy reflects in the direction of the earth. It warms the Earth’s surface and causes it to emit more infrared rays. This cycle maintains a warmer and livable atmosphere on the Earth.

Without such physical protection provided by the atmosphere, the Earth’s surface would appear like that of the moon. Thus, atmosphere makes the life possible on Earth.

Write A Brief Paragraph On Earth planet In English For Students

The earth revolves around the sun in a special circle called the orbital. Earth is the home not only of man but also of millions of other living beings, the only place in the universe where life exists.

Life on this surface began about a billion years ago. The ozone layer came into being in order for organisms to thrive. Along with the Earth’s magnetic field is the second layer of ozone that blocks the sun’s harmful radiation.

Earth is the only planet in the solar system where life exists .The outer surface of the earth is made up of mountains, sand and clay.

Mountains are essential for maintaining the balance of the earth’s surface. If we look at the earth from space, we will see big white marks.

These are water-filled clouds that are always present in the Earth’s atmosphere. The number of clouds that have affected the Earth’s atmosphere has decreased over the last few years. The earth has only one moon.

The northern hemisphere is more populated, while the southern hemisphere is less populated due to the greater number of oceans and less land, for a number of reasons (such as less knowledge of those areas in the past). The both North Pole and the South have six months of day and six months of night. Normal day and night duration is 24 hours.

History of Earth:

Scientific research has shown that the age of the earth is 4.54 billion years. Initially, the earth was in a molten state, but over time, water began to accumulate in the earth’s atmosphere and its surface cooled to form a crust. Shortly afterwards, the moon was formed.

Scientists believe that a body the size of Mars ,whose mass was one tenth of the Earth’s mass, collided with the Earth and as a result of this collision the moon came into being.

Essential elements of earth

The Earth’s atmosphere contains 78.08% nitrogen (N², dry air), 20.95% oxygen (O2), 0.930% argon, 0.039% carbon dioxide, water (climate change). The total surface area of ​​the earth is about 510,072,000 km2, of which 148,940,000 km2 or 29.2% is land and 361,132,000 km2 or 70.8% is water. In terms of area, about 71% of the earth’s surface is covered by saltwater seas, and the remaining 29% includes continents, islands and freshwater lakes.

Water is the beginning of life and water is essential for all forms of life, which do not currently exist on the surface of any planet in our solar system other than our earth.

Affect of human activities on Earth

The human population of the earth has exceeded 7.6 billion. And man is always engaged in wars over it. Due to overpopulation and human activities, the problems on earth that play an important role in life are disappearing. If this continues , there will be a time when resources will run out and there will be no life on earth.

Earth and resources of earth make life of human with all creations possible on it. If we somehow happened to envision our lives without these assets , that would not be conceivable. We should not do anything that somehow affects it and its resources and plant as many plants as possible on the ground because plants are very important to us.

Short Paragraph On Topic The Earth

Earth is the third planet from the sun and the only one that is seen from Earth’s surface. Earth is the only planet known to support life. It is home to a wide variety of animals, plants, and microorganisms, as well as human beings.

The atmosphere protects life on Earth by filtering out harmful solar radiation. The movement of tectonic plates beneath the surface of Earth creates the ocean basins, continents, and other geological features that are essential for the production of food and shelter. Without plate movement, life could not exist.

There are several types of soil on Earth: rocky soil includes rocks such as granite and basalt; loam soil is made up of loamy material such as sand and clay; clay soil has a lot of clay in it; silty soil has a lot of silt in it; heavy clay soils have a lot of clay in them; no matter what type of soil you find on Earth, the composition of each type can be very different.

Earth is made up of four layers; inner core, outer core, mantle and crust. The part of the Earth that is in the form of land is called crust. It includes oceans, rocks and mountains.

It is Earth’s thin, cold and rocky layer as compared to what lies beneath it. We live on this crust. It is made up of silicon, iron, calcium potassium and magnesium.

Mantle is Earth’s thickest layer and approximately 3000km in depth. It lies below the crust and surrounds the core. Since the temperature in this part is very high so the mineral matter is still in molten condition.

The outer core lies above the inner core. It is made from iron and nickel but it is a liquid layer which is responsible for Earth’s magnetic field.

This magnetic field acts as a protective shield around the Earth. The inner core also contains nickel and iron. It is too hot, around 5000 degree Celsius which is similar to the surface of sun.

Composition of Earth

The atmosphere of Earth is composed of 78% nitrogen, 21% oxygen and trace amounts of other gases. This atmosphere gets thinner when the distance from surface increases. Almost 75 percent of Earth is covered with water, 97% of which is saline in nature and just 3% is actually clean.

We use this 3% clean water for our basic needs. There are many natural resources on Earth like stone, sand, natural gases, metals oil and coal.

Rotation of Earth

Earth takes 365 days to complete its round around sun. It also rotates around its own axis and completes its rotation in 24 hours. In this rotation, we experience day when the earth faces sun and we experience night when it gets away from sun.

This visualization shows the CO2 being added to Earth's atmosphere over the course of the year 2021, split into four major contributors: fossil fuels in orange, burning biomass in red, land ecosystems in green, and the ocean in blue. The dots on the surface also show how atmospheric carbon dioxide is also being absorbed by land ecosystems in green and the ocean in blue. Though the land and oceans are each carbon sinks in a global sense, individual locations can be sources at different times.

This visualization shows the CO2 being added to Earth's atmosphere over the course of the year 2021, split into four major contributors: fossil fuels in orange, burning biomass in red, land ecosystems in green, and the ocean in blue. The dots on the surface also show how atmospheric carbon dioxide is also being absorbed by land ecosystems in green and the ocean in blue. Though the land and oceans are each carbon sinks in a global sense, individual locations can be sources at different times.

Carbon dioxide (CO2) is the most prevalent greenhouse gas driving global climate change. However, its increase in the atmosphere would be even more rapid without land and ocean carbon sinks, which collectively absorb about half of human emissions every year. Advanced computer modeling techniques in NASA's Global Modeling and Assimilation Office allow us to disentangle the influences of sources and sinks and to better understand where carbon is coming from and going to. This is equirectangular imagery intended for projection on NOAA Science-on-a-Sphere globe.

This visualization only shows the fossil fuel component of CO2 being added to Earth's atmosphere over the course of the year 2021.
