LEARN ABOUT THE LAYERS OF THE ATMOSPHERE

THE LAYERS OF THE ATMOSPHERE

The Earth is surrounded by layers of gases called the atmosphere, which is held in place by gravity. The atmosphere becomes thinner the greater the distance from Earth, with no clear boundary between the atmosphere and outer space.

Nitrogen gas makes up about three-fourths of the atmosphere. Other main gasses are oxygen, argon, and carbon dioxide.

Earth’s atmosphere has 5 main layers. The layers of the atmosphere in order from the lowest to the highest are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each area has different temperature changes, chemical compositions, movement, and density. Read on to find out how they differ from each and what the purpose of each layer is.

Troposphere

The troposphere is the atmospheric layer closest to the planet and contains 75% of the mass of the total atmosphere. It ranges from the Earth’s surface to an altitude of about 10–15 km or 4-12 miles. It also contains 99% of the water vapor and is where the weather occurs. You will notice the temperature in the troposphere decreases as the altitude increases.

The top of the troposphere is called the tropopause.

Stratosphere

Next is the stratosphere, which occurs at 4 to 31 miles or 10 to 50 km. The lower layers of the stratosphere are colder and the upper layers become hotter. It contains warm, dry air and little water vapor, which means it usually has no clouds.

The stratosphere is made up of mainly nitrogen and oxygen. But it also has a layer known as the ozone layer, which contains a high concentration of ozone. This is able to absorb most of the Sun’s ultraviolet radiation.  The ozone keeps most of the sun’s harmful radiation from reaching the earth.

The stratopause separates the stratosphere from the mesosphere. It is also considered the top of the stratosphere. Commercial airplanes generally fly in the lower stratosphere because there is less turbulence making for a more enjoyable ride!

Mesosphere

The mesosphere is the third layer of the atmosphere. It extends from about 50 to 85 km or 31 to 53 miles above the Earth. It is the coldest layer of the atmosphere. In fact, the coldest temperatures in the earth atmosphere are found at the top of this layer. The mesosphere is also where most meteors, and space junk, burn up before they can crash to the ground.

Thermosphere

The thermosphere is the fourth layer of the earth’s atmosphere. It is very hot as it absorbs radiation from the sun. The temperature increase is due to the absorption of solar radiation and ultraviolet radiation from the sun. The thermosphere puts on the auroras, amazing light displays in Earth’s sky caused by colliding particles in the top of the thermosphere. The thermosphere is also where satellites orbit the Earth. Even though the word “thermo” means heat, if you were hanging out in this layer, you would be pretty chilly because there aren’t enough molecules to transfer the heat to you! Because there aren’t enough molecules, it’s also hard for sound waves to travel as well. 

The ionosphere, although not shown is included in the Thermosphere. This region is full of electrically charged particles called ions and is where most auroras appear such as the Aurora Borealis or Northern Lights, and Southern Lights.

Exosphere

The exosphere is the most outer layer of the Earth’s atmosphere. This layer starts at 500 kilometers above the Earth’s surface and goes to about 10000 KM. It is mainly made up of light gases such as hydrogen, carbon dioxide, and helium. These gases are very spread out with a lot of space in between. They are light enough to escape Earth’s gravitational force and move into space.
