Answer 2

Answer:

One type of rock has changed to another type under the certain conditions in the “cyclic manner” called rock cycle.

Explanation:

• Under certain conditions, one type of rock cyclically changes to another type and form new kind of rock at the end of each step. This conversion is called the "rock cycle”.
• Mostly three kinds of rocks are present on the earth crust they are Sedimentary, Igneous and Metamorphic.
• Molten magma cools and solidifies in order to formed igneous rocks which break down to form “sedimentary rocks”.
• When exposed to sun and pressure, sedimentary and igneous rocks form metamorphic rocks and metamorphic rocks under high heat and pressure to form molten magma.
