Rock Cycle

According to the diagram, how does a sedimentary rock become a metamorphic rock?

• Weathering and Erosion

• Heat and Pressure

• Compaction and Cementation

• Melting

Identify the rock type: A volcano erupts and sends lava shooting into the air. This lava cools to form a(n) _____.

• Igneous        

• Sedimentary

• Metamorphic

• Mineral

According to the diagram, how does magma become an igneous rock?     

• Melting

• Cooling

• Heat and Pressure

• Compaction and Cementation

When pieces of older rocks, plants, and other loose material gets pressed or cemented together, a _____ rock forms.

• Igneous

    

• Sedimentary

• Metamorphic

• Mineral

Sedimentary rocks are made up of

• large rocks.  

• hard rocks.

• mostly igneous rocks

• small particles of sediment.

When molten (melted) rock cools and becomes a solid, a _____ rock forms.

• Igneous         

• Sedimentary

• Metamorphic

• Mineral

When heat or pressure causes one rock to change into a new type of rock, we call these rocks _____.

• Igneous     

• Sedimentary

• Metamorphic

• Mineral

Thinking about sedimentary rock, the oldest layers are found

• on the top most layer

• in the middle of other layers

• all layers are the same age

• towards the bottom

The breaking down of rock is caused by

• weathering

• erosion

• deposition

• sediment

Weathering breaks it….Erosion takes it…..Deposition

• Crushes it

• Moves it

• Drops it

• Rocks it
