Question 1

Biological weathering

Answer 1

Animals and plants can wear away rocks. Rabbits can burrow into a cracked in a rock, making it bigger and splitting the rocks

Question 2

Chemical weathering

Answer 2

Rain water is slightly acidic because carbon dioxide from the air dissolves in it. Minerals in the rocks may react with the rainwater, causing the rock to be weakened.

Question 3

Physical (freeze thaw)

Answer 3

Precipitation becomes trapped in the cracks or joints in the rocks. Temperature drops and water expands by 9-10% putting pressure on rocks. Ice melts when temperature rises. When this process repeatedly occurs, rocks weakens.

Question 4

Post glacial river process (lowland)

Answer 4

River erodes (vertically) creating misfit steams and deposits alluvium (fertile deposits)

Question 5

Post glacial river process (upland)

Answer 5

When climate gets colder (glacial period)chalk freezes turning impermeable. Water will run of surface eroding the valley

Question 6

Slope process (lowland)

Answer 6

Rockfalls/landslides. Rocks and debris side down

Question 7

Slope process (upland)

Answer 7

Dip slope is the lower outer slope
