Rocks on Earth are constantly changing due to natural processes. They are classified into three main types: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma or lava, sedimentary rocks form from compressed sediments, and metamorphic rocks form from existing rocks under heat and pressure. The rock cycle describes how these types transform into one another over time.

What is the primary reason rocks change their form on Earth?

• Due to artificial chemicals

• Because of natural processes

• Due to human activities

• They do not change form
