What caused most of the current landscape features of the Alps region?A. Tectonic plate movement

B. Ice movement and deposition of eroded material

C. Accelerated river erosion

D. Global warming

Answers

The correct answer is - B. Ice movement and deposition of eroded material.

During the last Ice Age, that finished around 10,000 years ago, the Alps were covered in snow and ice, and lots of glaciers. The movement of the numerous glaciers was the main factor behind the formation of the Alpine landscape features that we see nowadays. The glaciers made numerous valleys, cirques, U-shaped valleys, aretes, pyramidal peaks, truncated spurs. As the Ice age ended, all of these landscape features were revealed once most of the glaciers were gone, and we got the landscape that we see on the Alps in the present.

Most of the current landscape features of the Alps region was caused by ice movement and deposition of eroded material. The answer to your question is B. I hope this is the answer that you are looking for and it comes to your help.
