how is the atmosphere heated
Answers
Answer:
Explanation:
The atmospheric air is actually mostly heated at the ground surface, because on average the net radiation there is positive. This means that when we consider all types of radiation that incide at the ground surface (solar, short-wave radiation plus atmospheric long-wave radiation) and subtract all types of radiation that leave the ground surface (reflected short-wave radiation plus terrestrial long-wave radiation), on average we get a positive number; when accounting for all radiation energy at the surface, there is excess energy. Note by the way that all of these forms of radiation ultimately are due to the sun. The sun's radiation that reaches the surface of the earth is trapped by the greenhouse gas.

Plz MarK ME.
the air resting over the earth,s surface
gets directly heated by solar radiation when it contacts hot surface of the earth.
This heat is farther transmitted to the upper layers and the atmosphere gets heated.
