Types of Moraine
Geography: AQA GCSE, topic 3.4.5
Types of Moraine
Moraines are landforms that are left behind after a glacier melts. They are made of till and their position determines which of the four types a particular landform is:
Lateral moraine
- When an extended mound of till is deposited at the edge of a glacier, a lateral moraine is created.
- A lateral moraine is made up of material from the valley walls.
Medial moraine
- When an extended ridge of till is deposited in the middle of a valley, we call it a medial moraine.
- Medial moraines are formed where 2 glaciers join.
Ground moraine
- When till is carried underneath a glacier, a ground moraine is formed.
- Ground moraines are deposited across the valley floor.
Terminal moraine
- Made of till that was transported at the front of the glacier.
- Deposited at the glacier's snout.
