Which statement accurately describes outwash deposits?
Show answer & explanation
Correct answer: B
Explanation
Correct Answer:
Sorted, rounded sediments from meltwater streams
Explanation:
Outwash deposits are formed by meltwater streams flowing away from a glacier. These streams carry sediments and deposit them in layers according to size and weight. As a result, the sediments are well-sorted and rounded due to continuous transport and water action.
Key Points:
Outwash deposits are formed by glacial meltwater
They contain sorted and stratified sediments
Particles are usually rounded due to water transport
They are commonly found in outwash plains (sandur)
Additional Facts:
Outwash plains are formed in front of glaciers
They differ from till deposits, which are unsorted
Sand and gravel are common components of outwash deposits
Important Questions:
Q1: How are outwash deposits formed?
Answer: By meltwater streams carrying and depositing sediments
Q2: What is the nature of sediments in outwash deposits?
Answer: Sorted and rounded
Q3: What is the difference between till and outwash?
Answer: Till is unsorted, outwash is sorted
