(1) Which is an example of erosion?

Imagine a river flowing over rocks and soil, gradually wearing them down over time—this is erosion in action! The moving water picks up tiny particles, transporting them downstream and reshaping the landscape. It's like nature's own sculptor, chipping away at the earth’s surface, creating valleys and canyons that tell the story of the land's past. Erosion isn't just a natural phenomenon; it also impacts our day-to-day lives! For example, farmers need to be wary of soil erosion, as it can remove the nutrient-rich top layer of soil essential for crops. On a larger scale, controlling erosion is crucial for maintaining water quality in nearby ecosystems and preventing sediment buildup in rivers and lakes.
