The breaking down or disinigrating of substances such as rocks and minerals by physical, chemical, or biological processes is called-
A.Erosion
B.Weathering*****
C.Climate
D.Deposition
Correct
The correct answer is B. Weathering.
To arrive at this answer, we need to understand the definitions of the terms in the given options.
A. Erosion: Erosion refers to the process of moving and transporting weathered materials (such as rocks, soil, and sediments) by external agents like water, wind, or ice.
B. Weathering: Weathering is the process of breaking down or disintegrating rocks and minerals into smaller fragments by physical, chemical, or biological means. It occurs due to various factors like temperature changes, wind, water, ice, organisms, and chemical reactions.
C. Climate: Climate refers to the long-term atmospheric conditions of a specific region, including factors like temperature, precipitation patterns, wind patterns, and sunlight.
D. Deposition: Deposition refers to the process of depositing or laying down sediments, soil, or other materials that have been eroded and transported by wind, water, or ice.
Considering these definitions, the most accurate answer is B. Weathering, as it specifically describes the breakdown of substances like rocks and minerals by physical, chemical, or biological processes.
