What is the primary reason for the formation of many metamorphic rocks around the Earth's crust?

• The cooling of molten rock.

• The accumulation of sediments over time.

• Heat and pressure from the movement of tectonic plates.

• Erosion and weathering processes.

What causes an old rock to transform into a metamorphic rock?

• Exposure to water and wind.

• Extreme heat or pressure.

• Being broken down into sediments.

• Cooling from a molten state.

How are igneous rocks formed?

• From the compaction of sediments.

• When existing rocks are subjected to intense heat and pressure.

• When molten rock cools and hardens.

• Through the process of weathering and erosion.

Which of the following best describes the rock cycle?

• Rocks are permanently fixed in one form.

• Igneous rocks always turn into sedimentary rocks, which then turn into metamorphic rocks.

• Rocks can change from one type to another through processes like melting, cooling, pressure, and erosion.

• Only metamorphic rocks can transform into other types of rocks.
