Question

when can rainwater be an effective agent of weathering​

Answer 1

Explanation:

Erosion is a form of mechanical or physical weathering that occurs when the movement of a force like rain water or flood waters wear down the surface of rocks and carry the worn away parts to other areas. Erosion also occurs with forces like wind, glacier movement, or the action of high tides or waves along coastlines.

Answer 2

Answer:

When rocks, land formations and minerals begin to break down and dissolve, it’s called weathering. After crumbling, the process of erosion transports these broken bits away by wind or rain. Agents responsible for weathering include ice, salts, water, wind and plants and animals. Road salt and acids represent a form of chemical weathering, as these substances contribute to the wearing away of rocks and minerals as well.
