How do glacial processes shape the landscape?

Glacial processes are instrumental in shaping the landscape through a variety of mechanisms, primarily involving the movement and melting of glaciers. As glaciers advance, they exert immense pressure on the bedrock and erode the land beneath them. This results in the carving of distinctive features such as U-shaped valleys, fjords, and cirques. The erosion caused by glacial activity often leads to steep, rugged terrain, which contrasts with the smooth, rounded topography left behind by other forms of erosion, such as water.

Additionally, as glaciers melt, they leave behind unique landforms such as drumlins, moraines, and eskers, which are all formed from the debris that the glacier has transported and deposited. These processes not only alter the immediate landscape but also contribute to the ongoing evolution of geological features over time, highlighting the significant impact glaciers have on shaping terrains.

In contrast, the other answer choices do not accurately represent the processes involved in glaciation. While flat plains and plateaus can arise from other geological processes, they are not the primary outcomes of glacial activities. Desert formation is unrelated to glacial processes, as deserts are typically formed by arid conditions and lack of moisture. Lastly, stating that glacial processes have no significant impact diminishes
