Question

1. which of the following best describes how glaciers changed the landscape?

a. they bulldozed and scraped the land as they moved
b. they buried the land under sand
c. they melted mountains into rivers
d. they pushed the ocean inland

Explanation:

To determine the best description of how glaciers change the landscape, we analyze each option:

• Option A: Glaciers are massive masses of ice that move slowly. As they move, they erode the land by plucking (pulling rocks) and abrasion (scraping the land with rocks embedded in the ice), similar to a bulldozer scraping the land. This is consistent with glacial erosion processes.
• Option B: Burying land under sand is a process related to wind deposition (desert or beach processes), not glacial action.
• Option C: Glaciers do not melt mountains into rivers. Mountains are eroded by glaciers, and glacial meltwater can form rivers, but the process of melting mountains is not accurate.
• Option D: Pushing the ocean inland is not a typical glacial process. Glacial isostatic adjustment (after glaciers melt) can affect sea levels, but glaciers themselves do not push the ocean inland.

Answer:

A. They bulldozed and scraped the land as they moved
