Question

Short notes on layers of atmosphere:

troposphere ?
stratosphere ?
mesosphere and thermosphere ?
Lonosphere ?

Answer 1

TROPOSPHERE

the troposphere is the lowest layer of Earth's atmosphere and is also there nearly all weather condition take place.....Atop picture of a sphere is the tropuasewhich is important between troposphere and stratosphere.

STRATOSPHERE

the stratosphere is one of the layer of the atmosphere of the planet Earth. It distance from about 8 km above the poles (18 km above the equator) show about 50 km...... This makes is stratosphere very temperature gradient is caused by the Ozone layer which absorb some UV radiation from sunlight.

MESOSPHERE and THERMOSPHERE

the misosphere is directly above the stratosphere and below the thermosphere. It extends from above 50 to 85 Km (31 to 53 miles) above our increases with height throughout the mesosphere.
the thermosphereis the layer of the earth atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere ultraviolet radiation causes photoionization / photodissociation of molecules creating ions in the ionosphere.
