Question

What a Geologist Sees The photograph below shows large boulders scattered across polished bedrock in eastern Canada. Which of the following is the most likely explanation for the presence of these boulders? Choose one: A. They are pieces of resistant rock left behind by weathering. B. They were deposited during a flood. C. They were deposited by glaciers.

Answer 1

Option C => They were deposited by glaciers.

Step-by-step explanation:

Whenever we have a polished bedrock it is very important to know that the landscape can be found in places that are full of or has glacials. It is a process or phenomenon known as Glacial polish that causes large boulder in the area(even after the glaciers has melted). Therefore, option (C) is the correct Option in the question above.

Note that, the term " Glacial polish'' simply means the process in which the surface of bed rocks are grinded by graons and many or several pieces of rock.
