What type of water is found in lakes and rivers?

Back

Lakes and rivers contain fresh water, which is suitable for drinking and supporting life.

Front

What happens to salt in ocean water during evaporation?

Back

During evaporation, salt and other impurities are left behind, so the water that evaporates from the ocean does not contain salt.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the heat necessary for evaporation, driving the water cycle.
