# How far above the earth is the thermosphere?

## How far above the earth is the thermosphere?

Thermosphere. Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere. This layer is known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the earth.

How many km is each layer of the atmosphere?

Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles) Troposphere: 0 to 12 km (0 to 7 miles)

### How many kilometers above the Earth is air?

The clouds you see in the sky, the wind that is moving the trees or the flag in your school yard, even the sunshine you feel on your face—these are all a result of Earth’s atmosphere. Earth’s atmosphere stretches from the surface of the planet up to as far as 10,000 kilometers (6,214 miles) above.

Does the thermosphere start at 320 kilometers above sea level?

It starts at 320 km above sea level. 36. Why is the thermosphere so hot? Energy from the sun strikes the thermosphere first and nitrogen and oxygen convert the energy to heat.

## What can be found in the thermosphere?

In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air. Much of the X-ray and UV radiation from the Sun is absorbed in the thermosphere.

What is the altitude of exosphere?

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.

### Is between 80 and 110 km above the Earth’s surface?

thermosphere
The thermosphere contains an appreciable concentration of elemental sodium located in a 10-kilometre (6.2 mi) thick band that occurs at the edge of the mesosphere, 80 to 100 kilometres (50 to 62 mi) above Earth’s surface.

Do we live in thermosphere?

Humans live in the lowest layer called the troposphere. It is also the layer where all weather conditions occur. The layers above it are called the stratosphere, the mesosphere, and the thermosphere.
