WebThe term weathering refers to the destructive processes that change the character of rock at or near the Earth's surface. There are two main types of weathering: mechanical and … 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. ROCK COMPOSITION- Some minerals resist weathering.

5.2 Chemical Weathering – Physical Geology

WebThis is called weathering. Scientists categorize the processes that break down rock in two groups: physical and chemical weathering. Physical (also called mechanical) weathering happens when forces (pushes and pulls) repeatedly act on the rock. An example is wind repetitively gliding against a rock taking rock particles with it. WebSep 9, 2024 · There are multiple ways each type of weathering can occur and, therefore, both the rate that rock breaks down and how it breaks down vary dramatically depending on the area and environment. The most prevalent type of mechanical weathering is the collision, breaking, and grinding of rock by the movement of a fluid, either water or air.
