GEOLOGY

Detailed explanation-1: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-2: -Mechanical weathering-occurs when physical forces break rock into smaller and smaller pieces without changing the rock’s mineral composition.

Detailed explanation-3: -1. Weathering is a term which describes the general process by which rocks are broken down at the Earth’s surface into such things as sediments, clays, soils and substances that are dissolved in water. 2. The process of weathering typically begins when the earth’s crust is uplifted by tectonic forces.

Detailed explanation-4: -Chemical weathering weakens rocks making them more prone to breaking physically, while mechanical weathering increases the surface area of the sediment, which increases the surface area that is exposed to chemical weathering.
