a) a
b) b
c) c
d) d
e) a and d
Part 2-:

Part 4-:
The image shows an illustration of Antarctica. What is likely to be happening around the south pole?
a) this polar, continental ice sheet is actively flowing, moving rocks and sediments with it.
b) this temperate, alpine ice sheet is frozen solid to the rock beneath, resulting in very little movement and erosion.
c) this temperate continental ice sheet is relatively colder and less erosive in the middle than around its edges.
d) this polar, continental ice sheet is frozen solid to the rock beneath, resulting in very little movement and erosion.
e) none of the above are descriptive of the glacier at the South Pole.
Explanation / Answer
1 answer - erosion is more at C and transportation is at b.
Answer 2 - b
The rounded pebbles indicate that the rock is a conglomerate
Answer 3 - b and c are correct
U shaped valleys are always indicative of a glacier while v shaped valleys are indicative of rivers
