Question

1. many areas of the world that do not have adequate fresh water have become inhabitable because

a. rainfall patterns have changed.

b. water management projects have diverted water in the area.

c. icebergs have been towed in to provide fresh water.

d. people have practiced water conservation.

1. fresh water is a limited resource because *

a. most water is polluted.

b. most surface water contains salt.

c. it is controlled by powerful governments.

d. dams have limited the flow of fresh water.

1. which of the following is one way a person can conserve water?

a. take a long bath instead of a shower

b. wash laundry in small, partial loads

c. use a low - flow shower head to take short showers.

d. water the lawn daily and at mid - day

Explanation:

For question 12: Water management projects diverting water can lead to areas lacking sufficient fresh - water and becoming uninhabitable. Rainfall pattern changes (a) are more of a natural climate - related factor not directly related to human - caused lack of fresh - water in the context of the question. Towing icebergs (c) is not a common or widespread practice that would make areas uninhabitable. Water conservation (d) would help in water availability, not make areas uninhabitable.
For question 13: Most surface water is in the oceans (salt - water). Pollution (a) is a problem but not the main reason for it being a limited resource. Government control (c) is a social - political factor, not a natural - resource - based reason. Dams (d) are more about water management rather than the fundamental reason for it being a limited resource.
For question 14: Using a low - flow shower head and taking short showers reduces water usage. Taking a long bath (a) uses more water than a shower. Washing small partial loads (b) wastes water as full loads are more water - efficient. Watering the lawn daily at mid - day (d) is wasteful as it leads to more evaporation.

Answer:

1. b. water management projects have diverted water in the area.
2. b. most surface water contains salt.
3. c. use a low - flow shower head to take short showers.
