Question 1
Abrasion and plucking generally involve what part of a glacier?
Question 2
What is the difference between abrasion and plucking? a) Abrasion occurs when glaciers advance, while plucking occurs when glaciers retreat. b) Abrasion produces glacial erratics, while plucking produces striations. c) Abrasion involves wearing away bedrock through friction, while plucking involves wearing away bedrock through removal of rock fragments. d) Abrasion is caused by ice erosion, while plucking is caused by meltwater erosion.
Question 3
Answer to question 1
Abrasion and plucking occur at the bottom of a glacier when a glacier moves across the land’s surface by picking up everything in its path, including small pebbles to large boulders of rock. This may then cause these rocks to become frozen within the surface, which then continually move across the land leaving behind a jagged landscape.
Answer to question 2
abrasion is a type of erosiin where fine grains are removed by friction form the surface and plucking involves removal of large material from the bedrock.
So the correct option is (C).i. e. Abrasion involves wearing away bedrock through friction, while plucking involves wearing away bedrock through removal of rock fragments
Answer to question 3
Q33) ans: A) Abrasion occurs on the upflow side of a mound or hill that is scoured , while plucking occurs on the downflow side.
The abrasion action on upflow side due to high friction.
