Answer :
Final answer:
Abrasion and plucking generally involve the basal, sliding zone of a glacier.
Explanation:
Abrasion and plucking generally involve the basal, sliding zone of a glacier.
Abrasion occurs when rocks and debris carried by the glacier's ice grind against the underlying bedrock, wearing it away. Plucking, on the other hand, happens when the glacier's ice freezes onto the bedrock and pulls it away as the glacier moves.
Both processes primarily occur in the basal, sliding zone where the glacier gets in contact with the bedrock.

What is a glacier?
A glacier is a large mass of ice that is formed from compacted snow that has accumulated over many years. These ice formations are found in areas with temperatures that are consistently below freezing, such as in the polar regions or high mountain ranges. Glaciers can move slowly over time due to gravity and their own weight, carving out valleys and shaping the landscape as they go. They are important indicators of climate change, as changes in temperature and precipitation can cause glaciers to retreat or melt at an accelerated rate. Glaciers are also significant sources of fresh water, with many rivers and lakes being fed by their meltwater.
