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 processes such as basal sliding, where the glacier slides over the underlying rock and carries debris along with it.

The correct grid reference for part X is B 602 642.

1. Ribbon lakes are typically long and narrow, formed in a U-shaped valley that has been deepened by glacial activity.

2. They often have steep sides and can be characterized by their depth, which results from the erosional processes of glaciers.

Corries form through several key processes of glacial erosion. Initially, snow accumulates in a hollow, where it is compacted into ice. As the glacier moves, it undergoes rotational movement, deepening the hollow through a combination of abrasion and plucking of the bedrock. Over time, this process creates a steep-walled bowl-shaped depression known as a corrie. Meltwater can further enhance erosion by freezing and thawing at the ice's base, increasing rock loosening and removal.

In glaciated areas, development such as tourism and infrastructure can conflict with conservation efforts. For instance, while tourism generates income and creates jobs, it may lead to habitat disruption and increased pollution. On the other hand, conservation focuses on preserving natural landscapes and ecosystems, which can be at odds with the demands for land use, such as for housing or recreational facilities. Balancing these interests requires careful planning and consideration of the environmental impacts associated with development.
