Climate change

Question 1

Long term causes of climate change

Answer 1

Milankovitch cycles
Tectonic plate (ocean currents)

Question 2

Milankovitch cycles

Answer 2

100,000 year orbit
41,000 year tilt
21,000 year wobble

Question 3

Short term causes of climate change

Answer 3

Volcanic emissions (sulfur dioxide)
Variation in solar output

Question 4

What are polar glacial environments

Answer 4

Found in high latitudes e.g Artic
They have low precip and extreme cold temp

Question 5

What are Alpine glacial environments

Answer 5

Found at high altitudes in mountain ranges e.g Alps
They have high levels of precip, wide temp range

Question 6

What is a glacier

Answer 6

Slow moving bodies of ice in valleys

Question 7

What is a peri glacial environment

Answer 7

Doesn’t feature glaciers, usually found next to a glacier characterised with permafrost with varying seasonal temperatures

Question 8

Characteristics of a polar glacier

Answer 8

Polar environments e.g Antartica
Cold based glacier
Frozen to bedrock with melting only occurring at surface in summer

Question 9

Characteristics of temperate glacier

Answer 9

Alpine environments e.g Alps
Warm based glacier
Ice temp usually close to 0
More melting
