The Rock Cycle

Which of the following processes can form a mineral

• cooling of melted rock

• changing heat and pressure

• erosion of sediments

• None of the above

What happens to the matter beneath Earth's surface?

• It cools to form igneous rock

• It becomes magma

• It becomes lava

• All of the above

Sedimentary rock can be identified by:

• The yellow color

• the hardness of the rock

• the layers within the rock

• the location where the rock was found

Cooling magma below ground and cooling lava above ground both form

• sedimentary rock

• metamorphic rock

• igneous rock

• none of the above

Time scale for the formation of igneous rock:

• minutes to hundreds of thousands of years

• many thousands or even millions of years

• tens of millions of years

• none of the above

Time scale for the formation of sedimentary rock

• minutes to hundreds of thousands of years

• many thousands or even millions of years

• tens of millions of years

• none of the above

Metamorphic rock changes into sedimentary rock by:

• melting and cooling

• heat and pressure

• erosion and deposition

• all of the above

Metamorphic rock changes into igneous rock by:

• deposition and cementation

• heat and pressure

• erosion and deposition

• melting and cooling

Based on how it is formed, coal is a sedimentary rock.

• True

• false

A sedimentary rock could become a metamorphic rock by heat and pressure.

• True

• False
