Explanation:

The dashed circle indicates the process of infiltration because the water of precipitation goes inside the soil. Infiltration is the process in which water enters the soil through small opening present on the earth surface. When the clouds are formed, precipitation occurs in the form of rainfall and snowfall. Condensation is a process in which water vapors change into liquid when the environment has low temperature or cool so condensation occurs on the windows of Erica.
