Question
What is till and how is it formed during glacial processes?
Answer
Till is a type of sediment that is directly deposited by glaciers. It consists of a mixture of clay, silt, sand, and larger rocks that are transported and left behind as the glacier advances and retreats.
Explanation
This question tests the understanding of sediment deposition by glaciers, specifically focusing on the characteristics and formation of till. It requires students to explain the process of glacial movement and its impact on the landscape.
Common mistake
Common Misunderstanding of Glacial Deposition
Students often confuse till and outwash, thinking they are the same type of sediment deposited by glaciers.
Clarify that till is unsorted sediment deposited directly by glacial ice, while outwash is sorted sediment carried away by meltwater from the glacier.
