How does weathering contribute to the shaping of landscapes and the cycling of Earth's materials? (100 words)

Weathering, both physical and chemical, contributes to landscape shaping by breaking down rocks at Earth's surface into smaller pieces. This process creates soil, cliffs, and other landforms. Physical weathering, like freeze-thaw and exfoliation, fractures rocks, while chemical weathering, like oxidation and hydrolysis, alters their composition. The weathered material is transported by erosion, shaping the landscape further. Additionally, weathering plays a crucial role in the Earth's material cycle. It releases essential nutrients stored in rocks, making them available for use by organisms. Over time, these materials are cycled back into the Earth's crust through sedimentation, completing the cycle.
