Question

Quizplus · Accepted Answer

Glacial ice forms when snow is retained for many years and is compacted into ice by the weight of overlying snow. As more snow accumulates on top of the existing snow, the pressure compresses the lower layers into ice. Over time, the ice becomes more dense and hard, and eventually forms a glacier. This process is known as firnification.
