Complete Question:
Which of the following is a process that changes the composition of rocks from one material to another?
Group of answer choices.
A. Erosion
B. Deposition
C. Physical weathering
D. Chemical weathering
Answer:
D. Chemical weathering
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. <u>Physical weathering</u>: it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. <u>Chemical weathering</u>: it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
This ultimately implies that, chemical weathering refers to a process that changes the composition of rocks from one material to another. Some of the by products of chemical weathering are clay minerals, quartz, feldspar, muscovite, etc.
