1. The technicalities of how liquid water forms into ice are determined by water's ability to create which one of the following?
a. octagonal networks
b. surface tension
c. hydrogen bonds
d. heat of fusion
2. Assume that around Mount Kilimanjaro in Kenya, the ground temperature is about 30° C (88° F). Also assume a moist adiabatic lapse rate of 6° C/km. At what altitude would you expect to find ice on Mount Kilimanjaro?
a. 8 km
b. 5 km
c. 4 km
d. 6 km (By the way, Mount Kilimanjaro is high enough.)
3. Layers of melting and freezing can clearly be seen in which type of precipitation?
4. Mountain glaciers erode valleys into what shape?
a. staircase shape
d. square shape
5. Sea ice around Antarctica and in the Arctic Ocean affects which two processes?
a. latent heat of freezing and adiabatic lapse rate
b. thermohaline circulation and solar absorption
c. adiabatic lapse rate and solar absorption
d. thermohaline circulation and latent heat of freezing
6. Finish the calculation in the text. About how much would sea level rise if Greenland and Antarctica melted?
a. 90 meters
b. 10 meters
c. 20 meters
d. 70 meters
7. Greenland and Antarctica are examples of what type of ice formation?
a. sea ice
b. ice flows
c. ice sheets
d. dry ice
8. Long Island, New York State, is an example of which one of the following?
a. an esker
b. a drumlin
c. a holdar
d. a moraine
9. Which one of the following is true about sea level during the last ice age?
a. Sea level was lower and the O-18 to O-16 ratio of the ocean water was lower.
b. Sea level was higher and the O-18 to O-16 ratio of the ocean water was lower.
c. Sea level was lower and the O-18 to O-16 ratio of the ocean water was higher.
d. Sea level was higher and the O-18 to O-16 ratio of the ocean water was higher.
10. If sea level was 150 meters below today's level during the maximum of the last ice age, say, 20,000 years ago, then how much of Earth's water was locked up in ice? You'll have to use your calculation from question 6 because that gives you the sea level rise if Greenland and Antarctica melted. Recall that they together have 2.2% of the world's water. To answer the question of how much of the world's water was locked up in ice during the last ice age, include today's 2.2% for Greenland and Antarctica, and add to it the percent necessary to lower sea level by 150 meters. What's the total water locked up in ice during the last ice age?
1. c. hydrogen bonds
2. b. 5 km
3. d. hail
4. b. U-shape
5. b. thermohaline circulation and solar absorption
6. a. 90 meters
7. c. ice sheets
8. d. moraine
9. c. Sea level was lower and the O-18 to O-16 ratio of the ocean water was higher.
10. b. 5.9%
