Answer 2

continuous masses of ice over large areas of land

sheets or caps

Question 3

snow

Answer 3

frozen precipitation, often collecting in a thin layer on the ground.

Question 4

glacier

Answer 4

slow moving mass of ice formed by accumulation and compaction of snow over many years

Question 5

formation of glaciers

Answer 5

more snowfall than melt over years
mass of ice formed on land
movement or flow

Question 6

plastic flow

Answer 6

cold base
bottom frozen to bedrock.
higher velocity on top

basal slip

Answer 7

warm base

pressure melts ice at base, moving glacier equally

lunar day= 2 high, 2 low tides 24h 50m

Question 26

coastal straightening

Answer 26

water comes in heading towards headlands and gets pushed into bays and deposits
-seastacks get left, or arches and caves

terraces- land rises due to uplift

Question 28

depositional

Answer 28

beaches
sand spits- barrier islands
coastal dunes
