I WONDER - What Is A Metamorphic Rock?

Metamorphic rocks undergo transformation due to heat, pressure, or chemical processes deep within the Earth. These conditions cause mineral crystals to rearrange, altering the rock's texture, color, and appearance.

What are metamorphic rocks primarily altered by?

• Wind and water

• Heat, pressure, or chemical processes

• Freezing and thawing

• Erosion and sedimentation

Where do the changes in metamorphic rocks typically occur?

• On the Earth's surface

• In the ocean

• Deep inside the Earth

• In the atmosphere

What happens to mineral crystals in rocks under high temperatures and pressures?

• They dissolve completely

• They rearrange themselves

• They expand and contract

• They remain unchanged

How does the rearrangement of mineral crystals affect the rock?

• It makes the rock lighter

• It changes the rock's texture, color, and appearance

• It causes the rock to melt

• It makes the rock magnetic

Which of the following is NOT a result of the changes in metamorphic rocks?

• Change in chemical composition

• Change in overall appearance

• Change in color

• Change in texture
