Rain dislodges soil particles, leading to mechanical weathering. As water accumulates, it moves soil and rock particles, causing erosion. Fast-moving water erodes more than slow water, creating landscapes like meandering rivers and Oxbow lakes. Water also causes chemical weathering, dissolving rocks and minerals, forming caves and cliffs.
