what kinds of interactions occur between the atmosphere and the hydrosphere?

Question

i'm doing a report for my earth science class and i would appreciate any sources or facts related to the question.

Answer 1

Hydrosphere affects atmospheric pressure.The explanation is given below.
When heated by solar radiation,the hydrosphere produces water vapour which enters the atmosphere.The water vapour mixed with air behavs like any other gas.It contributes its own pressure to the total pressure of the atmosphere.Hence the pressure of a sample of air containing water vapour is the sum of the partial pressures of the air and water vapour.
Further, the abundance of water vapour on a sea or water surface exercises a blanketing influence by absorbing the out-going radiation and reradiating some of it back to the water surface.This prevents the atmosphere from experiencing extreme climate conditions and keeps the variation of atmospheric temperatures within limits particularly in tropics.
