Question

s are of interest to glaciologišts and climatologists because 1) ELA is an indicator of a glacier's ong term mass balance and therefore its health and 2) ELAs are like thermometers they go up systematically when it warms and down when it cools (precipitation can also have an effect, but for simplicity we consider temperature here). For the Canadian Rockies, for example, the last ice age catesed a-7 reduction in annual average temperature, and moved the ELA down approximately 1000 m. Paleo-ELAs (old ELAs inferred from landforms) are used as a tool for determining temperatures of past ice ages. 6) Terrace Mountain is approximately 6 km due south of the Saskatchewan Glacier. Of the glacier- related landforms discussed in class lectures, what is Terrace Mountain most likely to be? (1 pt) a) a tarn; b) an outwash plain; c) a horn; d) a drumlin 7) Given your answer in # area? (1 pt) what does the presence of Terrace Mountain tell you about glacier ice in the a) nothing; b) ice thickness was once less; c) ice thickness was once greater; d) the glacier ice 8) Immediately north of Terrace Mountain, there is presently a small glacier. Of the types of alpine here is cold-based glaciers described in class, which is it? (1 pt) a) a valley glacier; b a cirque glacier; c) a niche glacier; d) a piedmont glacier

Explanation / Answer

6 D Drumlin is an oval shaped hill,largely composed of glacial drift,which are formed beneath a glacier.

7 C it represents that once there was a greater thickness of ice in the glacier.

8 C Niche glaciers are small,occupies small gullies and hollows on north facing slopes.
