Final answer:
Water is the most powerful agent of erosion, reshaping the Earth's surface through processes like river carving and wave erosion.
Step-by-step explanation:
The most powerful agent of erosion is water. Water can erode land and reshape the Earth's surface through processes such as rivers carving out valleys, waves eroding coastlines, and rainwater wearing away rocks over time. As water flows, it picks up sediment and carries it downstream, gradually wearing away the landscape. For example, the Grand Canyon in the United States was formed by the erosive power of the Colorado River.
