Detailed explanation-1: -Glacial erosion can physically change rocks in many ways, such as the following major ways: Ice can freeze in the cracks of rocks after rain, causing the ice to expand the cracks and lead to pieces of rock breaking off. Flow of glaciers “plucking” rocks up from the base of the flow.
Detailed explanation-2: -Glacial erosion is primarily driven by abrasion of the underlying rocks by rock fragments embedded within the ice. These rocks are pushed down onto the underlying surfaces by the ice, and because they are hard they can gouge and grind down the materials beneath the glacier.
Detailed explanation-3: -Glacier can also shape landscapes by depositing rocks and sediment. As the ice melts, it drops the rocks, sediment, and debris once contained within it. Ice at the glacier base may melt, depositing Glaciers can also move sediment from one place to another when it flows over sediment beds.
