Earth’s Water & the Hydrosphere
This term refers to all of Earth’s water, including oceans, lakes, groundwater, and water vapor.
Hydrosphere
This source provides the energy that powers the water cycle.
The Sun
Which process forms clouds?
Condensation
Water is known as the __________ solvent.

What is it called when water molecules stick to each other?
Cohesion
Name one place water can be found on Earth besides oceans.
Rivers, lakes, glaciers, groundwater, atmosphere (any one)
Water changing from liquid to gas requires an input of this.
Energy (heat)
How is transpiration different from evaporation?
