• Foliated and Non-foliated

• Clastic and Chemical

Which of the following is a characteristic of intrusive igneous rocks?

• They form on the Earth's surface.

• They have large crystals.

• They are formed from sediment.

• They are layered.

What is the primary process involved in the formation of sedimentary rock layers?

What type of rock is formed when existing rocks are subjected to heat and pressure?

• Igneous

• Sedimentary

• Metamorphic

• Volcanic

Which process is responsible for the transformation of rocks into metamorphic rocks?

• Cooling

• Weathering

• Heat and pressure
