Sure! Here are examples for both erosion and weathering caused by water:
**Erosion Example:** A river flowing through a valley can erode the riverbanks over time, carrying away soil and rock material. As the water moves, it removes sediments and shapes the landscape, creating features such as river canyons or meanders.
**Weathering Example:** The presence of water can lead to the weathering of rocks through a process called hydrolysis. For example, when rainwater, which is slightly acidic due to dissolved carbon dioxide, seeps into cracks in granite, it can chemically alter the feldspar minerals in the rock, breaking them down into clay minerals over time.
These processes illustrate how water plays a crucial role in shaping the Earth's surface through both erosion and weathering.
