Rocks and Rock Cycling

Which of the following leads most directly to the production of igneous rock?

• formation of magma
• cementation of rocks
• weathering of rocks
• deposition of sediment

Which is the best way to complete this model of the rock cycle?

• crystallization
• solidification
• heat and pressure
• melting

What is a step in the process of a rock changing from sedimentary to igneous?

• weathering
• deposition
• erosion
• melting

Which of the following can occur after a rock is weathered?

• it forms metamorphic rocks
• it melts and forms igneous rock
• the sediment can form magma
• it gets compacted and forms sedimentary rock

When rocks are buried below the surface, pressure combined with heat causing which type of rock to form?

• metamorphic
• igneous
• sedimentary

The cementing of small pieces of rock or shell causes this type of rock to form

• igneous
• sedimentary
• metamorphic

Evan examines a diagram of the rock cycle in his science textbook. He wonders how he can connect what he has learned about matter and energy to the rock cycle. Which statement explains what happens to material as it moves through the stages of the rock cycle?

• new matter is being created all of the time
• the same matter is recycled over and over
• eventually the broken down matter disappears
• old matter is destroyed and new matter takes its place

The process by which igneous rocks are formed

• heat and pressure
• compaction and cementation
• melting, cooling and crystallizing
• weathering and erosion

This process changes rocks to magma

• melting
• weathering and erosion
• cooling and crystallizing
• heat and pressure

This process takes sediments and changes them to sedimentary rock

• weathering and erosion
• heat and pressure
• compacting and cementing
• melting
