Unit 2 Lesson 5: The Cycling of Earth's Material

What is a rock?

• A type of gas

• A type of metal

• A natural, solid mixture of minerals

• A type of liquid

How do igneous rocks form?

• When molten rock cools and crystallizes

• By exposure to extreme temperatures

• By compaction and cementation

• From weathering and erosion

What are clastic sedimentary rocks made up of?

• Dissolved minerals in water

• Broken pieces of minerals and rock fragments

• Organic materials

• Crystals formed from water evaporation

What are chemical sedimentary rocks composed of?

• Crystals formed from water evaporation

• Broken pieces of minerals and rock fragments

• Dissolved minerals in water

• Organic materials
