Rock Cycle

What type of rock is created through the compaction and cementation of rock pieces?

• Igneous

• Sedimentary

• Metamorphic

Answer explanation

Sedimentary rocks are also where we find fossils.

Which process has to happen before other rocks can turn into sedimentary rocks?

• deposition

• melting

• compaction

• weathering

• erosion

Answer explanation

Weathering breaks down rock material but erosion and deposition also play a part in creating sedimentary rocks.

Geologists have classified rocks into three major groups of rocks which are:

• inorganic

• igneous

• chemical

• sedimentary

• metamorphic

Any rock that forms from another rock as a result of changes in heat or pressure (or both) is a:

• chemical rock

• igneous rock

• sedimentary rock

• metamorphic rock

Answer explanation

The base word morph means to change.

The process by which metamorphic rock changes to igneous rock begins with

• melting

• erosion

• deposition

• crystallization

Answer explanation

Igneous rock is formed through the cooling of magma.

Which type of rock is created by the cooling of magma either below or on top of Earth's crust?

• sedimentary

• inorganic

• igneous

• metamorphic

Answer explanation

Igneous rock that forms under Earth's crust is called intrusive. When it forms on top of Earth's crust it's called extrusive.

This rock started as molten magma. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

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

• Sedimentary
• Igneous
• Metamorphic
