Answer:
There could be a number of causes for a well to contain less and less water every year. A decline in the water table brought on by excessive use or drought circumstances, cracks or leaks in the well casing or pipes, or modifications to the local geological formations that affect the flow of water into the well are a few potential causes. It would be better to seek the advice of a specialist or well-informed person to evaluate the particular issue and pinpoint the root problem.
B. Ice movement and deposition of eroded material
C. Accelerated river erosion
D. Global warming
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.
