Astudent compared the chemical composition of soil in a certain area with the bedrock beneath it. she found that the chemical compositions were different. which statement would best explain the difference in chemical composition? a. the area's rain and extreme temperatures caused the soil to develop. b. the rainwater washed iron oxide from the a horizon to the d horizon. c. the soil is all that is left of a different kind of rock that weathered away. d. the soil layers were mature because a large amount of time had passed

Option (A)

Explanation:

The factors namely the temperature and rainfall plays a very significant role in maintaining the quality of the soil. A comparatively warmer temperature along with abundance of rainfall helps the soil to gain nutrients and increases its fertility. But a cooler temperature with lesser amount of rainfall does not provide the necessary elements to the soil. As a result of which the soil loses its fertility. In nature, these two factors occurs simultaneously, that controls the chemical composition of the soil.

Thus, the correct answer is option (A).

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

the question isn't complete here so i can't right an answer '_'
