1. Wind Causes Weathering and Erosion Wind causes weathering by blowing bits of material against cliffs and large rocks. This wears and breaks the rock down into sand and dust. Wind also erodes sand and dust.
2. Weather on Earth is caused by heat from the sun and movement of the air. ... The sun's heat warms the air in this layer to different temperature levels in different places. Warm air rises, and cold air then rushes in underneath to replace it.
3. Animals can also contribute to weathering. Animals can walk on rock or disturb it, causing landslides that scrape or smooth rock surfaces. Burrowing animals such as badgers and moles can break up rock underground or bring it to the surface, where it is exposed to other weathering forces.
4. There is overwhelming evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean, and land surface to ...
5. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. When water freezes, it expands.
