Jun 25, 2024 · Earth’s atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space.
- Exosphere. This is the outermost layer of the atmosphere. It extends from about 375 miles (600 km) to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.
- Thermosphere. Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere, known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the Earth.
- Mesosphere. This layer extends from around 31 miles (50 km) above the Earth's surface to 53 miles (85 km). The gases that comprise this layer continue to become denser as one descends.
- Stratosphere. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). This layer holds 19 percent of the atmosphere's gases but very little water vapor.

This is the first and the lowest layer of Earth’s atmosphere. All life on this planet is affected by the changes that happen in this layer, as all the weather changes take place in the troposphere. It starts from the ground (or sea level) of our planet and expands up to 10 km up in the sky. This is when we talk about the levels of oxygen, the one l...
If we start from the top of the troposphere and go further into the sky, we reach the layer known as the stratosphere. This layer goes up around 50 km above the Earth’s ground. In this layer, the temperature rises as you go further up, and it has something to do with the ozone layer that is found inside the stratosphere. The ozone layer serves a vi...
As the name suggests, we are halfway up our atmosphere layers when we reach this part. The mesospheregoes up to 85 km above the surface of our planet, and the temperatures here behave as they do in the troposphere. In essence, the higher you go, the colder it gets. The air in this layer is absolutely not friendly for us, as it would be impossible t...
The layer that is located between 500 and 1000 km above the Earth’s level is known as the thermosphere. You have guessed it, high temperatures are the name of the game here. This layer is under constant attack from the X-rays and UV radiationcoming from the Sun and the space around us. Because of this, the temperatures in this layer can even reach ...
Unlike other layers, which are mostly distinguishable from one another, it is hard to say how far the exosphereis from the surface of the planet. Somewhere it is around 100,000 km, but it can expand up to 190,000 km above sea level. The air here is extremely thin, and the conditions here are more similar to the ones we find when we leave the Earth’...
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.
May 3, 2022 · The atmosphere is the layer of gases that surround Earth. The five layers of the atmosphere, in order from the ground up, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere extends to roughly 100 km or 62 miles.
Oct 2, 2019 · Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
