The Rock Cycle

What can happen to igneous rocks through weathering and erosion?

• They can be broken down into smaller pieces creating sediment
• They become harder and more resistant
• They turn into metamorphic rocks
• They disappear completely

How are extrusive igneous rocks formed?

• Through erosion
• By compaction
• On the surface of the Earth when lava cools quickly

• Beneath the Earth's surface

How are metamorphic rocks different from sedimentary rocks?

• Sedimentary rocks are formed through melting
• Metamorphic rocks are always black in color
• Metamorphic rocks are softer than sedimentary rocks
• Metamorphic rocks are formed through heat and pressure, while sedimentary rocks are formed through compaction and cementation

Why is understanding the rock cycle important for scientists?

• It helps in space exploration
• It helps interpret the history of our planet and predict future geological events
• It is not important for scientific research
• It is just a theoretical concept

What is the process that changes the texture of rocks through extreme heat and pressure?

• Erosion
• Melting
• Metamorphism
• Deposition

How are sedimentary rocks formed?

• By melting and solidifying
• By compacting and cementing layers of sediment
• By exposure to extreme cold temperatures
• Through volcanic eruptions

What happens to rocks that are broken down through weathering and erosion?

• They become harder
• The cycle begins again
• They turn into liquid
• They disappear completely

What process can transform sedimentary rocks into metamorphic rocks?

• Melting
• Deposition - compaction and cementation

• Erosion
• Metamorphism - heat and pressure

How are igneous rocks formed?

• By compacting layers of sediment
• Through the process of erosion
• By exposure to extreme heat from the sun
• When molten rock cools and solidifies
