Compare the information from the two graphs. Choose True or False for each sentence:

There is less salt water where Alice lives compared to the amount of salt water where Diego lives.

• True

• False

Alice has more total fresh water where she lives, but Diego has more fresh water that is actually available to use (for drinking and washing his hands).

Why is that?

*Select all that apply.

• The freshwater where Alice lives is mostly frozen.

• There is mostly saltwater where Alice lives.

• Frozen water isn't available for drinking, so there is less to drink.

• Alice just needs to learn to thaw the water.

Alice has more total fresh water where she lives, but Diego has more fresh water that is actually available to use (for drinking and washing his hands). Why is that?

• Because much of Alice's fresh water is frozen or hard to access, while Diego's is more accessible.

• Because Diego lives near the ocean and can use salt water.

• Because Alice uses more water for farming than Diego does.

• Because Diego has more rainfall than Alice.
