Question

Name five layers of the atmosphere?

Answer 1

Atmosphere:

• The earth is surrounded by an invisible thick layer of air called the atmosphere.
• It extends to thousands of kilometers above the surface of the earth.
• It protects the earth’s surface from harmful radiation from the sun.
• Without the atmosphere, there could be no life on earth.
• The atmosphere is mainly composed of five layers: These are troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Troposphere:

• It is the nearest layer to the earth's surface.
• In this layer we can see clouds.
• All the weather changes occur in this layer.

Stratosphere:

• It is the second layer of the atmosphere.
• This layer consists of the ozone layer which protects us from harmful ultraviolet rays.

Mesosphere:

• It is the third layer of the atmosphere.
• Meters that enter the earth's atmosphere get burned in this layer and are seen as shooting stars.

Thermosphere:

• It is the fourth layer of the atmosphere.
• In this layer satellites orbit the earth.

Exosphere:

• It is the outermost layer of the atmosphere.
• The temperature of this layer is very low.
