The wаter, оr hydrоlоgic, cycle describes the pilgrimаge of wаter as water molecules make their way from the Earth's surface to the atmosphere and back again, in some cases to below the surface. Studies have revealed that _______ —the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water (lakes, rivers, streams) provides nearly 90% of the moisture in our atmosphere. Most of the remaining 10% found in the atmosphere is released by plants through _______ . Plants take in water through their roots, then release it through small pores on the underside of their leaves. In addition, a very small portion of water vapor enters the atmosphere through _______ , the process by which water changes directly from a solid (ice or snow) to a gas.
