WebIt can literally wash away soil and carve away rock bit by bit, which scientists describe through two separate processes. When water breaks rocks apart, it's called weathering. And when water carries away surface soil, sediments, and that broken down rock it's called erosion. Erosion by water starts with rain. WebAdditional causes of physical weathering include the freezing and expansion of water in rock cracks, and tree roots that dig into rocks that can split them apart. Chemical weathering occurs when the breakdown of rock results from chemical change in the rock, or the when the rock is dissolved away.
