from the atmosphere to Earth's surface?
A.Infiltration
B.Precipitation
C.Transpiration
D.Sublimation - Correct Answer -B.Precipitation
Precipitation is the process by which atmospheric water falls to Earth's surface in
the form of rain, hail, sleet, or snow. Because atmospheric water returns to Earth's
surface primarily through the process of precipitation, it is an important part of the
water cycle. Infiltration is the process by which water on Earth's surface enters the
subsurface soil and rock. Transpiration is the process by which water evaporates
from plant leaves and enters the atmosphere. Sublimation is the process by which a
