What is the relationship of the three types of rocks in a rock cycle?
​

Answer 1

Answer:

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

Answer 2

Answer:

Rocks are formed, broken down, and reformed into different types of rocks. The rock cycle shows the relationships among the three major rock types: igneous, sedimentary, and metamorphic.

• Igneous rocks form when molten material cools and hardens.

• Sedimentary rocks form when loose sediments that were previously eroded from existing rocks are lithified.

• Metamorphic rocks form when pre-existing rocks are subjected to heat and pressure.
