Weathering

Question 1

erosion

Answer 1

wearing away and breakdown of the land by wind water or ice

Question 2

slumping

Answer 2

soil becomes saturated and slides downhill in stages . creates uneven land with steps

Question 3

mudslide

Answer 3

soil becomes saturated and slides downhill in a single movement

Question 4

freeze thaw

Answer 4

water gets into cracks in the rock, freezes overnight and expands causing rock to crumble

biological weathering

Answer 5

breakdown of rock by plants or animals

Question 6

physical weathering

Answer 6

breakdown of rock my non-chemical processes

Question 7

chemical weathering

Answer 7

breakdown of rock by acid that involves a chemical reaction between elements

Answer 20

weathering

Question 21

example of biological weathering + explanation

Answer 21

burrowing animals and plant roots. burrowing animals/plants attack rocks and weaken their structures, like a rabbit burrowing into a crack in a rock.

Question 22

example of physical weathering +explanation

Answer 22

exfoliation. flaking of outer surface of rocks due to repeated cycles expansion and contraction because of hot and cold environment

Question 23

example of chemical weathering + explanation

Answer 23

solution. dissolving of rock due to the presence of acid
