d.
all of the above.
d ?

The answer is D all of the above

Answer;

D. all the above

Water may enter the atmosphere through all the above processes;

Liquid water evaporates from lakes when heated by the sun. Frozen water sublimates from ice and snow. Liquid water is lost from tree leaves during evapo-transpiration.Explanation;Water may enter the atmosphere through the processes of transpiration, evaporation, excretion and also sublimation.Evaporation occurs when heat from the sun makes water from the surfaces of water bodies such as seas, lakes and oceans evaporate and changes from liquid form to gaseous form water vapor in the atmosphere.Transpiration is the process by which plants loose water to the atmosphere in form of water vapor through the stomata found in the leafs of the plants. This is also a process through which water enters the atmosphere.Sublimation is also another process that facilitates the water to enter the atmosphere through change of water from solid form, snow or ice to water vapor in the atmosphere.
