The correct answer is:
B. One type of rock can be changed into another type of rock.
Explanation:
The rock cycle is a fundamental concept in geology that describes the processes through which rocks are formed, altered, destroyed, and reformed over time. It illustrates how different types of rocks can be transformed from one form to another through various geological processes. For example, sedimentary rocks can be transformed into metamorphic rocks through processes like heat and pressure, and metamorphic rocks can be further changed into igneous rocks through melting and solidification. This continuous cycle of rock formation, alteration, and transformation helps scientists understand the dynamic nature of Earth's geology and the interactions between different rock types.
