Freshwater Resources: Main Ideas

Where is Earth’s usable fresh water found?

(pg. 204-205)

a) Ice sheets and glaciers

Quick Check (pg. 205)

-Critical Thinking: What are some other bodies

of water that people can use as a source of

water?

a) Stream, rivers, lakes, reservoir and water table

2) What is a watershed? (pg. 206-207)

a) Where the underground water feeds a specific river or lake

Quick Check (pg. 207)

-Critical Thinking: How could changes made

to land far away from a river affect its

flow?

a) The water in the water table could dry up which would affect the amount of water in a river or lake far away.
