Question

what is a glacier? how could a massive chunk of ice carve out valleys and create lakes? explain what glaciation means and identify an example of a lake that was formed by glacial processes.

Explanation:

A glacier is a large, slow - moving mass of ice formed from compacted snow over many years. As a glacier moves, its immense weight and pressure can carve out valleys through abrasion and plucking (picking up rocks and debris). Glaciation refers to the process of glacier formation, movement, and the resulting geological changes. An example of a lake formed by glacial processes is Lake Tahoe. Glaciers carved out the basin, and when the ice melted, water filled the depression to form the lake.

Answer:

A glacier is a large mass of ice. Glaciers can carve valleys due to their weight and movement. Glaciation is the process related to glaciers. Lake Tahoe is an example of a glacial - formed lake.
