Question
Which of the following will tend to increase the rate of chemical weathering of minerals in a rock?Group of answer choicesDecrease in rainfallIncrease in temperatureAll answers are correctIncrease in freeze-thaw cycles
Solution
C. All answers are correct
All the options provided can increase the rate of chemical weathering of minerals in a rock.
-
Decrease in rainfall: This is incorrect. An increase in rainfall would actually increase the rate of chemical weathering as water is often a necessary component of many chemical weathering processes.
-
Increase in temperature: Higher temperatures can increase the rate of chemical reactions, including those involved in the chemical weathering of rocks.
-
Increase in freeze-thaw cycles: While this is more related to physical weathering, it can also increase the rate of chemical weathering. The freeze-thaw process can create cracks in rocks, increasing their surface area and making them more susceptible to chemical weathering.
So, the correct answer should be an increase in rainfall and temperature, and an increase in freeze-thaw cycles.
