8S1 Geography Mid Year Revision

Question 1

What is plucking?

Answer 1

When the rotational slip rips some of the loose rock on the mountain, that is called plucking.

Question 2

What is freeze-thaw

Answer 2

Freeze-thaw is when water fills in the cracks of the mountain and during the night it freezes and expands by 9%

Question 3

What is an Arete?

Answer 3

An arete is the knife edged ridge in between two corries.

Question 4

What is a pyramidal peak?

Answer 4

A pyramidal peak is the top sharp point when three or more corries are next to each other.

Question 5

What is the name of the water at the bottom of a corre”

Answer 5

A tarn.

Question 6

What is the usual depth or a glacier.

Answer 6

30 metres of more.

Question 7

What is firn?

Answer 7

Snow that has not been compacted.

Question 8

What is morainne?

Answer 8

It is the deposited rock from the rotational slip at the end of a corrie.

Question 9

What does morainne act as?

Answer 9

It is there as a dam to stop the tarn from leaking.

Question 10

Name all of the cold environmensts in the world.

Answer 10

Himalayas K2 mountain which is located in asia above india. Logan mountain is on the west side of United states, cotaxi volcan which is in south america near the equator and kilamanjaro which is in africa.

Question 11

What is a cold environment?

Answer 11

An area that is permanently covered by ice. They are covered by glaciers, ice sheets and have frozen soil/rock.

Question 12

How do glaciers advamce?

Answer 12

If glaciers input is greaters than their output, glaciers advance.

Question 13

How do glaciers retreat?

Answer 13

If their input is less than their output they retreat.

Question 14

What is the accumulation zone?

Answer 14

The accumulation zone is where there are inputs into the glacial budget.

Question 15

What is the ablation zone?

Answer 15

The ablation zone is where there are outputs from the glacial budget.

Question 16

Explain how U shaped valleys are formed

Answer 16

A glacier forms in a V shaped valley and it moves through it and erodes the sides making it in the shape of a U

Question 17

How are V shapes valleys made?

Answer 17

When a valley is lead by a river and the river erodes the bottom of the valley and creates interlocking spurs.

Question 18

How do you see how steep a landscape is on an OS map?

Answer 18

You use contour line, the closer the lines are, the steeper the landscape is.

Question 19

What is the sentence that you use to find a 4 or 6 figure reference?

Answer 19

Along the stairs and up the corridor.

Question 20

Where is most of the fresh water on earth and water percentage is it in?

Answer 20

69 percent of the fresh water on earth is in ice.

Question 21

Explain the first step if how a corrie is made.

Answer 21

First snow accumulates in a north-east facing hollow. The firn is compacted into ice and is turned into a glacier. Once the glaciers reaches a depth of 30 metres, it begins to have a rotational slip.

Question 22

Explain the second step of how a corrie is made.

Answer 22

Water fills in the cracks of the mountain, during the night the water freezes into ice expanding by 9%, loosening the lose cracks. The rotational current of the glacier plucks the lose rocks dragging it with the current. The current uses the rocks to abrade the mountain down. While the glacier is rotating, extra pieces of rock is brought to the end of the mountain which is called morainne.

Question 23

Explain the last step of how a corrie is formed.

Answer 23

The corrie is formed into a shape of an armchair shape with a steep back wall. The glacier melts and the left over water in the corrie is called a tarn. The morainne at the end acts as a dam.

Question 24

What is a misfit river.

Answer 24

A misfit river is a river that’s too small to have eroded the valley.

Question 25

What is latitude?

Answer 25

Latitude is how north or how south something is on the globe.

Question 26

What is altitude?

Answer 26

Altitude is the distance above sea level.

Question 27

How does latitude and altitude affect cold environments?

Answer 27

The further away the cold environment is from the equator the colder it would be. And the higher the altitude is (the further away it is from sea level) it makes it colder.

Question 28

What is scree

Answer 28

Any material that has broken off the glacier from freeze thaw weathering.
