Detailed explanation-1: -Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering.
Detailed explanation-2: -Wind, water, ice and human activities are some of the causes of erosion. Weathering is caused due to atmospheric factors like air pressure. Erosion and weathering together degrade soil and wear away shorelines and cliffs.
Detailed explanation-3: -Erosion is one that most everyone is familiar with. This is the removal of sediment such as sand, silt or gravel, by wind or water. Weathering is the breaking down of rock material by things like heating and cooling, frost or crystal wedging, or chemicals, like acid in rain.
Detailed explanation-4: -Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth’s surface breaks down rocks into small and smaller pieces. These smaller pieces of rock (such as sand, silt, or mud) can be deposited as sediments that, after hardening, or lithifying, become sedimentary rocks.
