Unit 4: Earth's Materials

Which processes must occur in order for an igneous rock to change into a metamorphic rock?

• heating and pressure

• compaction and cementation

• melting and cooling

• uplift and erosion

This rock started as molten magma deep under the Earth's crust. What type of rock is this?

• Sedimentary

• Intrusive Igneous

• Metamorphic

• Extrusive Igneous

This rock was another type of rock that was changed by heated and compression over time. What type of rock is this?

• Sedimentary

• Igneous

• Metamorphic

How does metamorphic rock change into sediments?

• Increase Heat and Pressure

• Exposure and Weathering

• Melting

• Compaction and Lithification

What are the 3 major types of rocks?

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

When weathering breaks rocks into pieces, what do we call those smaller pieces?

• texture
• weathering
• sediment
• erosion

This type of rock is formed from layers of sediment over Millions of years that are compacted due to pressure

• Metamorphic

• Igneous

• Sedimentary
