Question

Which one among the subsequent isn't the agents of weathering?
(A) Water
(B) Ice
(C) Soil
(D) Temperature

Answer 1

Hint: The Appalachians offer a superb example of weathering. Wind, rain, and erosion brought this towering range down from 30,000 feet to only over 6,600 feet high.

Complete Answer:
- When rocks, land formations, and minerals begin to interrupt down and dissolve, it’s called weathering. After crumbling, the method of abrasion transports these broken bits away by wind or rain. Agents liable for weathering include ice, salts, water, wind, and plants, and animals. Road salt and acids represent a sort of chemical weathering, as these substances contribute to the erosion of rocks and minerals also
- Erosion may be a sort of mechanical or physical weathering that happens when the movement of a force like rainwater or flood waters affect 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.
- Freeze and thawing present another sort of mechanical weathering. you'll observe this in cold regions that have below freezing temperature drops during the night, then warm-ups during the day. When water freezes on a road after a rain, becoming ice, it expands the affected surface. because the road thaws and repeatedly freezes during winter, the expanding process creates instability, leading to potholes.

Hence correct option is (A).

Note: Glaciers, winds, and rainwater are the agents of weathering which imply they're the forces that perform the breakdown of materials over the surface Soil is the material that is made because of the results of weathering hence it's not the agent of weathering and this is often the proper answer.
