What is the altitude of the thermosphere layer?

600 kilometers
The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.

What is the upper part of the thermosphere?

Exosphere
The lower part of the Thermosphere, a layer of ionised air extending from the Mesopause to approximately 600km is also known as the Ionosphere, while the upper part of the Thermosphere is also known as the Exosphere.

What is the altitude of the top of the troposphere?

about 33,000 feet
The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer).

Why is thermosphere the hottest layer?

The thermosphere and the exosphere together form the upper atmosphere. Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere.

What is the altitude of thermosphere on Earth?

The thermosphere ranges in altitude from 90 km to 600+ km. It is a realm of meteors, auroras and satellites, which skim through the thermosphere as they circle Earth. It is also where solar radiation makes first contact with our planet.

Which is thicker the thermosphere or the atmosphere?

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.

Which is the third highest layer of the atmosphere?

The mesosphere (literally middle sphere) is the third highest layer in our atmosphere, occupying the region 50 km to 80 km above the surface of the Earth, above the troposphere and stratosphere, and below the thermosphere. It is separated from the stratosphere by the stratopause and from the thermosphere by the mesopause.

What is Earth’s upper atmosphere?

Upper Atmosphere. The Earth’s atmosphere has four primary layers: the troposphere, stratosphere, mesosphere, and thermosphere. These layers protect our planet by absorbing harmful radiation.
