What is the name given to a large boulder transported and deposited by glaciers in areas with a different rock type? Shade one circle only - AQA - GCSE Geography - Question 5 - 2023 - Paper 1

Glaciers move material through a process known as entrainment, where the glacier's ice picks up and incorporates rocks and sediment from the landscape as it flows.

The six-figure grid reference for the part of the corrie marked X is B 602 642.

1. Ribbon lakes often form in glacial valleys that have been deepened by the carving action of glaciers. These lakes tend to be long and narrow, following the contour of the valley.

2. They may have steep sides due to the erosional processes of the glacier, which can lead to distinct geological features along the shorelines.

Corries form through a combination of processes:

1. Snow collects in a hollow on the mountainside, which eventually transforms into ice as it compacts over time.

2. The ice moves under pressure, primarily through rotational movement and induces erosion by plucking at the back wall and sides of the corrie, deepening the hollow.

3. As the glacier retreats, it leaves a characteristic bowl-shaped depression known as a corrie, often with a tarn (small lake) at its base.

In glaciated areas, development such as tourism (e.g., zip-wires, hiking trails) can significantly boost local economies by providing jobs and enhancing infrastructure. However, this development may conflict with conservation efforts designed to protect fragile ecosystems and landscapes.

For instance, increased foot traffic and construction can damage the natural environment, leading to soil erosion and loss of biodiversity. Additionally, noise and pollution from tourist activities may disrupt local wildlife habitats.

Thus, there is a constant balancing act between fostering economic growth and safeguarding environmental integrity, where careful planning and sustainable practices become crucial.
