Answer:
The process of weathering wears away rock formations. When rocks are chipped away or shattered, such as when water seeps into a fissure and freezes, expanding and fracturing the rock apart, mechanical weathering occurs. When the chemical makeup of a rock or mineral is altered, chemical weathering can occur. Rainwater combining with limestone, for example, causes chemical weathering. Erosion, on the other hand, happens when small fragments of rock or sand are blown around or become entangled in river currents and scraped against other rocks (leading to mechanical weathering).
