True
The process of water vapor cooling and changing back into liquid water is called ______.
Condensation
Which process in the hydrological cycle involves liquid water falling to the ground?
Precipitation
Multiple choice: Which of the following is NOT a component of the hydrological cycle?
A) Evaporation
B) Photosynthesis
C) Precipitation
D) Infiltration

What is infiltration?
Infiltration is the process by which water on the ground surface enters the soil.
True or False: Runoff occurs when water flows over the land surface and returns to bodies of water.
True
What do plants contribute to the water cycle?

What is groundwater recharge?
Groundwater recharge is the process by which water infiltrates the ground and replenishes aquifers.
True or False: Snowmelt can contribute to runoff in the spring.
True
What is the term for the water cycle’s process of returning water to the atmosphere?
Evaporation
Water that is stored in glaciers and ice caps is called ______.
Cryospheric water
What happens during the process of condensation?
Water vapor cools and transforms into liquid water droplets.
