Worked Solution & Example Answer:Feature of glacial erosion Name one feature of glacial erosion and with the aid of a diagram, explain how it was formed - Junior Cycle Geography - Question A - 2008
Step 1
Feature of glacial erosion
Answer
One feature of glacial erosion is the formation of a U-shaped valley. This occurs when a glacier moves through a valley, eroding the walls and floor, which results in a distinctive U-shape.
Diagram
A labeled diagram should illustrate a typical U-shaped valley, showing the glacial movement and the resultant valley shapes.
Explanation
The glacier's weight and movement cause plucking and abrasion, leading to the valley's gradual widening and deepening as it travels.
Step 2
Feature of glacial deposition
Answer
A notable feature of glacial deposition is moraine. Moraines are accumulations of debris deposited by glaciers as they melt and retreat. They can be found along the edges or at the terminus of a glacier.
Diagram
Include a labeled diagram of a moraine showing its location relative to the glacier.
Explanation
As glaciers advance, they pick up rocks and soil, which are then deposited in piles as the glacier retreats, forming moraines.
