"WebMost weathering occurs on exposed surfaces of rocks and minerals. The more surface area a rock has, the more quickly it will weather. When a block is cut into smaller pieces, it has more surface area. So, therefore, the smaller pieces of a rock will weather faster than a large block of rock 3.

WebNutrients can occur naturally because of weathering and erosion of rocks and soils and breakdown of organic material (Hem, 1985; USGS, 2000), but also from anthropogenic activities, including point and nonpoint sources. Examples of point-source inputs include discharge from industrial sources and effluent from municipal wastewater treatment plants. WebPhysical weathering, sometimes called mechanical weathering, includes all the processes which break rocks apart without changing their chemical composition. Following are examples of physical weathering processes. Rock Abrasion Rock abrasion occurs when rocks collide with one another or rub against one another.
