Glacial Landscapes in the UK

Question 1

Relief of the land

Answer 1

Refers to the highest and lowest elevation points in an area. e.g. mountains and rivers are typically the highest elevation points

Question 2

Topography

Answer 2

The natural features of land, especially the shape of its surface.

Question 3

Altitude

Answer 3

Height above sea level, measured in metres or feet.

Question 4

Land use

Answer 4

The purpose or function of land for example pasture, grassland, retail.

Question 5

Lowland

Answer 5

Are close to or below 200m above sea level. One example is the Fens in East Anglia.

Question 6

Uplands

Answer 6

Are normally made up of mountains or high hills. Normally they are areas over 600m above sea level. Examples include the Cumbria mountains in the Lake District.

Question 7

Glacial erosion

Answer 7

The wearing away and removal of the land by flowing water, ice or wind.

Question 8

Plucking

Answer 8

Is where a glacier moves over an area of rock. Due to friction, the glacier melts and water seeps into cracks around the rocks below. The water freezes and the rock effectively becomes part of the glacier and is ripped out when the glacier continues to move forward.

Question 9

Abrasion

Answer 9

Is where rocks at the bottom of the glacier act like sandpaper - grinding over the bedrock. This can polish the rocks or create sharp grooves called striations.

Question 10

Bulldozing

Answer 10

When a glacier moves forward it can act like a giant earthmover, bulldozing piles of rock debris in front of it to create a high ridge called moraine. The furthest advance of a glacier is marked by a terminal moraine.

Question 11

Glacial Till

Answer 11

Sediment transported by ice.

Question 12

Moraine till

Answer 12

Sediment that is deposited

Question 13

Outwash

Answer 13

Sediment carried by meltwater. Is more rounded due to attrition by river erosion.

Question 14

Corrie

Answer 14

Corries are bowl shaped hollows with a steep back wall and ridges, forming an armchair shape around a hollow sometimes containing a small round lake called a tarn.

Question 15

Aretes

Answer 15

A freeze-thawed ridge that develops when 2 corries are side by side/back to back.

Question 16

Pyramidal Peaks

Answer 16

Are produced as the corries erode the mountain behind, the rest is weathered into a sharp point.
