Zain · Answer 1

I find the best answer to be the following one:

B. Glaciers scraped across the surface and altered landscapes and the course of rivers.

The altered landscape can be described as: rather smooth landscape with characteristic rocks scattered though it.

The course of rivers is shaped because the rivers flow in the valleys through which the glaciers traveled.

While glacier-created landscape might support specific ecosystems, glaciers themselves did not create ecosystems, so I would keep to answer B.

Jocelynn Koch · Answer 2

In my opinion, the correct answer among the choices presented above is option B. Glaciers would impact the surface of the Earth by scraping across the surface and altering landscapes and the course of rivers. Also, glaciers has the possibility to raise sea levels.
