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

27
Locations of cold environments usually depend on either latitude, altitude, or continentality. Are cold environments usually found in high latitudes or low latitudes?
High latitudes
28
Locations of cold environments usually depend on either latitude, altitude, or continentality. Are cold environments usually found in high altitudes or low altitudes?
High altitudes
29
There is a cold environment on every continent. (TRUE/False)
True
30
Glaciers are a system with inputs, processes and outputs. It is called...
A Glacial budget
31
Where there are inputs into the glacial budget
Accumulation
32
Where there are outputs from the glacial budget
Ablation
33
What might happen in the zone of ablation
Melting due to temperature rise
34
Shape of a glacial valley
U shaped valleys with steep sides, a wide valley floor. It flows in a straight shape.
35
We can see glacial features on OS maps. How could you see steep land on an OS map?
The contour lines are close together
36
To find a grid reference you follow what rule.
Along the corridor, up the stair
37
Where is the majoity (69%) of the world's fresh water held
In ice
38
What is the percentage of the fresh water held in ice?
69%
39
Ice is melting faster than ever. What ice melt is going to add more to the rising sealevels?
Glacier Ice
40
Read Filippo's example of a summary the fomation of a corrie in 3 key steps.
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.
