Question

Describe how a glacier affected the surrounding land in this valley. As the glacier moved slowly through the mountain valley, it acted like a giant! the sides of the valley through a process called the glacier; of the surrounding rocks. This is when the rocks were broken down into smaller pieces. The glacier also scraped and ground down The weight and movement of the ice caused which is when those broken pieces of rock were carried away by the moving ice. As over time, it left behind all the rocks, gravel, and dirt it had gathered up. This is known as :: boulder :: deposition :: bulldozer :: erosion 00 to create new landforms like moraines and outwash plains in the valley. This process shaped the valley into the broad, U-shaped form that you can see in the picture, which is typical of valleys that were once filled with glaciers.​

Answer 1

Glaciers transform valleys through erosion, acting like bulldozers as they move, and transport materials like rocks and gravel. These materials are eventually deposited, creating new landforms like moraines and outwash plains, and leading to the characteristic U-shaped valleys.

Step-by-step explanation:

As a glacier moves through a valley, it acts as a bulldozer, reshaping the land through a process called erosion. Glaciers erode the sides of the valley, breaking down rocks into smaller fragments and scraping the earth beneath them. This powerful action causes weathering of the surrounding rocks, where they are broken down into sediments such as rocks, gravel, and dirt.

The weight and movement of the ice lead to transportation of these fragments, which are then carried away by the moving glacier. This is a critical aspect of the glacier's role in shaping the landscape. Over time, as the glacier retreats, it leaves behind these materials through a process called deposition, resulting in the creation of new landforms such as moraines and outwash plains. The valley, once occupied by the glacier, becomes recognizable by its broad, U-shaped form, indicative of past glacial activity.
