Rocks and Minerals Chapter 2 and Three

How are sedimentary rocks, such as shale and sandstone, formed?

• Particles are changed into liquids.

• Particles are melted together by magma.

• Particles are compressed into layers.

• Particles are heated by the Sun.

In order for sediments to become rock, the sediments are generally

• Liquified

• compacted

• returned to their origins.

• mixed with organic material.

Which of these substances is a mineral?

• Sandstone

• Quartz

• coal

• granite

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

• Heating and pressure

• melting and cooling

• compaction and cementation

• uplift and erosion

Which process forms both metamorphic and sedimentary rock?

• Recrystallization

• weathering

• heating

• compacting

Which processes change magma into igneous rock?

• weathering and erosion

• compaction and cementation

• heat and pressure

• cooling and crystallization

Minerals are made of one or more

• Minerals

• Elements

• Sediments

• rocks

One rock was formed from rapidly cooling lava and is smooth and glassy. The other rock was formed from slow-cooling magma, so has large crystals. Which rock property is represented by these characteristics?

• color

• texture

• fracture

• hardness

Which process causes sand grains to stick together to form sandstone?

• Cementation

• combustion

• erosion

• abrasion

Which type of rock is formed when particles are compacted and cemented together?

• igneous

• Sedimentary

• Metamorphic

• metallic
