Question

what is atmosphere ? name the different layers of the earth

Answer 1

Layers of the atmosphere
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere. The different layers of the atmosphere
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.

The red line on the figure below shows how temperature varies with height (the temperature scale is given along the bottom of the diagram). The scale on the right shows the pressure. For example, at a height of 50 km, the pressure is only about one thousandth of the pressure at the ground.

Answer 2

• The blanket of air around the earth is called atmosphere.

• The atmosphere is comprised of layers based on temperature.
• These layers are the troposphere, stratosphere, mesosphere and thermosphere.
