Question

Essay about difference layers of the earth

Answer 1

Answer:

1.Troposphere

2.Stratosphere

3.Mesosphere

4.Thermosphere

5.Exosphere

Explanation:

1.Troposphere:This is the lowest layer of atmosphere which is the closest to the surface of earth.Since water vapour and dust particles are present in this layer,all weather occurs within this layer.Air is warmest at the bottom of the troposphere and higher up it gets colder.There is a boundary between the top of the troposphere and stratosphere called tropopause.

2.Stratosphere:The second layer of the atmosphete is stratosphere.The boundary between stratosphere and mesosphere is called stratopause.Ozone,which is abundant in the stratosphere,heats this layer as it absorbs energy from incoming ultraviolet radiation from the sun.

3.Mesosphere:Mesosphere is the layer after stratosphere.In mesosphere with higher altitudes the temperature becomes colder.The mesosphere has the coldest temperature in the atmosphere,dipping as low as-120 °celsius(-184°Fahrenheit,or 153 kelvin).Most meteors from space burn up in this layer because of air resistance and friction.

4.Thermosphere:This layer is directly above the mesosphere.Temperature slowly increases in the lower thermospherevand then begins to level off.

5.Exosphere:The exosphere is the uppermost layer ,where the atmosphere thins out and merges with interplanetary space.It is located directly above the thermosphere.This layer has very scattered gases and the gravitational pull of earth is minimum in this layer.
