Q

Map symbols

A

An image or letters used on maps to show a specific feature

18
Q

Erosion

A

Wearing away and removal of material

19
Q

Sea level rise

A

Increased sea levels. With climate change, sea levels are rising

20
Q

Thermal expansion

A

Change of water volume with heat.

21
Q

Freeze thaw weathering

A

Water gets into cracks in the rocks freezes and expands

22
Q

Tarn

A

Deep lake at the base of a corrie filled with water

23
Q

Basal sliding

A

Glacier moving over the bed with melt water acting as a lubricant

24
Q

Abrasion

A

Rocks in the glacier scrape over the land and wear it away

25
Q

Corrie? Where on the mountain?

A

A deep arm chair shaped hollow found in the side of a mountain, The north face

26
Q

Abraded Man

A

Old Harry

27
Q

Locations of cold environments usually depend on either latitude, altitude, or continentality.
Are cold environments usually found in high latitudes or low latitudes?

A

High latitudes

28
Q

Locations of cold environments usually depend on either latitude, altitude, or continentality.
Are cold environments usually found in high altitudes or low altitudes?

A

High altitudes

29
Q

There is a cold environment on eve ry continent.
(TRUE/False)

A

True

30
Q

Glaciers are a system with inputs, processes and outputs.
It is called…

A

A Glacial budget

31
Q

Where there are inputs into the glacial budget

A

Accumulation

32
Q

Where there are outputs from the glacial budget

A

Ablation

33
Q

What might happen in the zone of ablation

A

Melting due to temperature rise

34
Q

Shape of a glacial valley

A

U shaped valleys with steep sides, a wide valley floor. It flows in a straight shape.

35
Q

We can see glacial features on OS maps.
How could you see steep land on an OS map?

A

The contour lines are close together

36
Q

To find a grid reference you follow what rule.

A

Along the corridor, up the stair

37
Q

Where is the majo ity (69%) of the world’s fresh water held

A

In ice

38
Q

What is the percentage of the fresh water held in ice?

A

69%

39
Q

Ice is melting faster than ever. What ice melt is going to add more to the rising sealevels?

A

Glacier Ice

40
Q

Read Filippo’s example of a summary the fo mation of a corrie in 3 key steps.

A

Snow builds up in a hollow on the side of the mountain and forms a glacier.

The glacier erodes downwards using processes such as abrasion (using rocks to scrape and erode), plucking (breaking off chunks of rock from the mountain) and freeze-thaw (when meltwater gets into cracks, freezes and expands to weaken the rock).

The glacier then eventually melts leaving behind an armchair-shaped corrie with a steep back wall and a tarn in the middle.

41
Q

Name 4 Cold Environments

A

Arctic Antartica Kilamanjaro, Russia, Iceland, Greenland and more
