Which of the following statements is true? the lower the number of living organisms in an area, the higher the rate of weathering will be. rocks rich in calcium, potassium, and sodium, weather into fertile soil. raindrops and snowflakes are too light to cause erosion. wind erosion removes the least fertile part of soil.

The lower the number of living organisms in an area, the higher the rate of weathering will be.

Weathering is a process in which the rocks gets broken down into smaller parts and sediments. Weathering brings a physical and chemical change in the weathered material distinct from parent rock.

The lower the number of living organisms in an area, the higher the rate of weathering will be because living organisms use rocks as a substratum to survive. Plants and animals occupies the surface of rocks, for their growth and utilize them as habitat. Therefore, will prevent weathering of rocks. Lack of colonization of living species will directly expose the rocks to physical (wind and water) and chemical (acids, alkalies and gases) agents. This will increase the rate of weathering.  

looks like the answer is     c     to me!
