PROPERTIES OF ROCK, GEOLOGICAL HISTORIES OF ROCKS AND FORMATION

Which of the following is NOT one of the three types of rock?

• Metamorphic

• Magma

• Sedimentary

• Igneous

Answer explanation

The types of rock: igneous, metamorphic and sedimentary

Which of the following processes produces metamorphic rocks?

• Rapid burial

• Gradual cooling

• Regular deposition

• Extreme pressure

Answer explanation

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

In order to be classified as metamorphic, a rock must–

• have been completely melted.

• change with heat and pressure.

• be made of small bits of larger rock.

• have formed very quickly.

Answer explanation

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

What is one of the most common processes that turns sediments into sedimentary rocks

• Organisms in the soil breaking down organic matter into useful chemicals

• Minerals within rock layers growing into large crystals over time

• Layers made of bits of broken rock pressing down on other layers

• Magma cooling under the surface of Earth, crystallizing to form rock

A rock deep within the Earth experiences extreme temperature and pressure. After a long period of time it becomes which rock?

• Magma

• Igneous

• Metamorphic

• Sedimentary

What are the 3 major types of rocks?

• Igneous, Metamorphic, Sedimentary
• Metamorphic, Igneous, Cementation
• Brown, Red, Gray
• Streak, Hardness, Breakage

What is hardness?

• The tendency of a mineral to split easily along flat surfaces.

• A measure of how easily a mineral can be scratched.

• The way a mineral shines, or reflects light.
