Which of the following describes ice changing the Earth's surface by erosion?

• Water freezes in the cracks of rock causing bigger cracks to form.

• A mound of rock is left as glacier ice melts and the glacier retreats.

• Sediment frozen in the ice of a glacier moves as the glacier moves.

• Heavy ice presses down on sediment causing the formation of sedimentary rock.
