Which layer of Earth's atmosphere extends from the mesopause to the thermosphere?
- Troposphere. Temperature: 62°F (17°C) around the lowest point to -60°F (-51°C) near the top. The troposphere is the lowest layer of the atmosphere, and it is where we live.
- Stratosphere. Temperature: -60°F (-51°C) near the tropopause to 5°F (-15°C) near the next layer. Lies just above the troposphere, extending up to 31 miles (50 km) high.
- Mesosphere. Temperature: Ranges from 5°F (-15°C) to -148°F (-100°C) as one ascends up the layer. The mesosphere extends from just above the stratosphere to 53-62 miles (85-100 km) high.
- Thermosphere. Temperature: The temperatures in this layer depend on solar activity and can get as hot as 930°F (500°C) to 3,600°F (2,000°C) near the upper thermosphere.

Of all the atmosphere's layer's, the troposphere is the one we're most familiar with (whether you realize it or not) since we live at its bottom -- the Earth's surface. It hugs the Earth's surface and extends upward to about high. Troposphere means, ‘where the air turns over’. A very appropriate name, since it is the layer where our day-to-day weat...
The stratosphere is the next layer of the atmosphere. It extends anywhere from 4 to 12 miles (6 to 20 km) above Earth's surface up to 31 miles (50 km). This is the layer where most commercial airliners fly and weather balloons travel to. Here the air doesn’t flow up and down but flows parallel to the earth in very fast moving air streams. It's temp...
Starting roughly 31 miles (50 km) above Earth's surface and extending up to 53 miles (85 km) is the mesosphere. The mesosphere's top region is the coldest naturally occurring place on Earth. Its temperatures can dip below -220 °F (-143 °C, -130 K)!
After the mesosphere and mesopause come the thermosphere. Measured between 53 miles (85 km) and 375 miles (600 km) above the earth, it contains less than 0.01% of all air within the atmospheric envelope. Temperatures here reach upward to 3,600 °F (2,000 °C), but because the air is so thin and there are so few gas molecules to transfer the heat, the...
Some 6,200 miles (10,000 km) above the earth is the exosphere -- the atmosphere's outer edge. It is where weather satellitesorbit the earth.
The ionosphere isn't its own separate layer but is actually the name given to the atmosphere from about 37 miles (60 km) to 620 miles (1,000 km) high. (It includes the top-most parts of the mesosphere and all of the thermosphere and exosphere.) Gas atoms drift into space from here. It is called ionosphere because in this part of the atmosphere the ...
- 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.
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.
- Troposphere. 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.
- Stratosphere. 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.
- Mesosphere. As the name suggests, we are halfway up our atmosphere layers when we reach this part. The mesosphere goes up to 85 km above the surface of our planet, and the temperatures here behave as they do in the troposphere.
- Thermosphere. 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.
The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
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.
