Discussion

• Do you know what an Ice Age is?
• Ice Age - a period in time when there was a
  long-term reduction in the temperature of the
  Earths surface and atmosphere, resulting in an
  expansion of ice sheets and glaciers.
• How do you think Scotland has been affected by
  the ice?

• U-shaped Valley
• Corrie
• Corrie Loch

U-shaped Valley

The formation of a U-shaped Valley

• The U-shaped valley begins as a V-shaped valley
  carved by a river.
• When a glacier flows through this V-shaped valley
  the power of ice scrapes away at the surface
  widening, deepening and steepening the valley.

Corrie and Corrie Loch

• A circular hollow in the side of a mountain

13
Formation of Corrie

• Snow Gathers in a hollow in the mountainside.
• Overtime this snow compacts into ice to form a
  glacier.
• Under gravity the glacier starts to move down the
  mountainside, due to the shape of the hollow it
  curves.
• As it does this it steepens the back of the
  hollow and deepens the base creating a larger
  hollow in the mountainside.
• The shape almost resembles an armchair steep
  back with two arm rests!

• When the glacier has melted, the hollow which is
  left fills with water.
• This is called a corrie loch or tarn.

Activity

• Collect the Glaciation features sheet.
• Copy the diagrams into your jotter.
• Select the correct labels to ANNOTATE your
  diagrams. Write the labels beside the diagram and
  draw an arrow to the part of the diagram it is
  referring to.
• If you finish before the rest of the class, start
  the extension questions on Page 10.

Drawing and annotating diagrams is an important
geographic skill.
