Rock Cycle

Granite is a coarse or medium-grained rock that is rich in quartz and feldspar. It is formed when bodies of magma cool and harden deep below the earth. What type of rock is granite?

• sedimentary

• intrusive igneous

• extrusive igneous

• metamorphic

Molten hot magma that cools very slowly can cause ______________ in igneous rock.

• the formation of large crystals

• glass-like formations

• settling of precious metals

• mineral layering

Which is an example of a chemical change that occurs as part of the rock cycle?

• sedimentary rocks are worn away by water erosion

• sedimentary rocks are turned into metamorphic rocks by heat and pressure

• lava cools and condenses on the Earth's surface

• igneous rocks are cracked and broken into smaller pieces by weathering

What causes sedimentary rock to change into metamorphic rock?

• weathering and erosion

• melting

• heat and pressure

• cooling

How does wind cause weathering?

• Wind can blow sand and create new landforms.

• Wind can not cause the weathering of rocks.

• Wind picks up sand or dry soil and carries it from one place to another.

• Blowing sand can wear away a rock's surface and break it down.

Igneous rock is formed by the cooling and solidification of molten Earth materials. Igneous rock forms when magma or lava cools. If underground pockets of magma _________________ and solidify, ________________ igneous rock is formed, such as granite.

• cools quickly, intrusive

• cools quickly, extrusive

• cools slowly, intrusive

• cools slowly, extrusive

Which statement about metamorphic rock is true?

• It can be created from sedimentary rock.

• It is created from magma.

• It forms through crystallization.

• It is created through lithification.

Which set of characteristics best describes igneous rock?

• least abundant type of rock, made of other rocks, made mostly of minerals

• largest type of rock, made of organic matter, hardest type of rock

• most abundant type in Earth's crust, made of magma/lava, contains no fossils

• found on all continents, contains wavy bands of stripes, contains fossils

Shale is formed from clay, silt or mud particles that have been compacted together by pressure. What type of rock is shale?

• extrusive igneous

• sedimentary

• metamorphic

• intrusive igneous

Which set of characteristics best describes sedimentary rock?

• often contains layers, forms near sources of water, contains fossils

• most abundant type in Earth's crust, made of magma/lava, contains no fossils

• least abundant type of rock, made of other rocks, made mostly of minerals

• largest type of rock, made of organic matter, hardest type of rock
