Types of Rocks

Rocks are broken up into three major groups:

• magma, metamorphic, and minerals

• igneous, metamorphic, and sedimentary

• sedimentary, sand, and igneous

• sand, mud and silt

Rocks that come out of volcanoes form the greater part of the Earth's crust. These rocks are:

• igneous rocks

• basalt

• metamorphic rocks

• granite

Which of the following is NOT one of the three types of rocks?

• Igneous

• Sedimentary

• Magma

• Metamorphic

Metamorphic rock forms as a result of:

• heat and pressure

• cooling of magma

• compaction of sediments

• melting of rock

Lava that cool so quickly that crystals do not have time to form will lead to igneous rocks with a:

• porphyritic texture

• coarse-grained texture

• glassy texture

• fine-grained

Which of the following represents the correct order of the processes responsible for the formation of sedimentary rocks?

• Erosion, weathering, compaction, cementation, deposition

• Compaction, cementation, deposition, weathering, erosion

• Deposition, cementation, compaction, erosion, weathering

• Weathering, erosion, deposition, compaction, cementation
