two difference between thermosphere and exosphere
(pointwise)
Answers
Explanation:
thermosphere
● The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere.
●Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere.
●At these high altitudes, the residual atmospheric gases sort into strata according to molecular mass (see turbosphere).
● Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation.
exosphere
●atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is too low for them to behave as a gas by colliding with each other.
● In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere is the uppermost layer, where the atmosphere thins out and merges with interplanetary space.
● It is located directly above the thermosphere.
● Very little is known about it due to lack of research.
is that troposphere is the lower levels of the atmosphere extending from the earth's surface up to the tropopause it is characterized by convective air movements and a large vertical temperature change whileexosphere is the uppermost layer of a planet's atmosphere.
