Part 1 Multiple choice questions 1) Which one of the following is NOT true of glaciers? A) They originate on land. B) They exist only in the Northern Hemisphere C) They show evidence of flow (either in the present or in the recent past) D) They form from the recrystallization of snow 2) When a valley glacier leaves the mountains and enters the relative flat lands below, i may spread out to form A) an ice cap B) a piedmont glacier C) an ice shelf D) a lateral moraine 3) If accumulation exceeds ablation in a glacial budget, which of the following will happen? A) The terminus will move downhill (“advance”) B) The terminus will shift uphill (“retreat”). C) The glacier will begin to flow uphill. D) The glacier will melt away due to climate change. 4) Under typical conditions, glaciers flow A) at a rate between 2 meters (6.5 feet) and 800 meters (2600 feet) per year B) throughout the entire glacial ice mass C) at a rate between 1.6 to 8 kilometers per hour (1 and 5 miles per hour) D) only when the snow is falling 5) In an area of alpine glaciation, sinuous, sharp-edged ridges called pyramid-like peaks called A) tarns; cirques B) cirques; arêtes C) arêtes; horns D) horns; hanging valleys and sharp, are common features. 6) How is desert different from steppe? A) Steppe is more humid than desert. B) Desert is more humid than steppe. C) Desert occurs at subtropical latitudes, but not at mid-latitudes in continental interiors D) Steppe occurs at subtropical latitudes, but not at mid-latitudes in continental interiors.
1) B, they existed only in northern hemisphere
This statement is false. Because we find so many glaciers in
southern hemisphere. For example Antarctic glaciers.
2) B, a piedmont glacier
3) A, the terminus will move downhill (advance)
5) C, arete and horns
Arete is the sharp Ridge.
6) A, steppe is more humid than desert
Under less rainfall steppe can be converted to desert and under
high rainfall desert can be converted to steppe.
