Rock Cycle & Age of Earth

If a sedimentary rock is exposed to intense heat and pressure but does not melt, it can become which type of rock over time

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

• Magma

If an Igneous rock experiences weathering and erosion, it can be broken down into sediment. Which type of rock is formed by the compaction and cementation of sediment?

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

• Magma

Granite forms when liquid magma slowly cools within Earth's crust. If the granite is exposed to intense heat and pressure, it can change to gneiss. Which type of change takes place when granite turns into gneiss?

• Sedimentary rock changes to igneous rock.

• Igneous rock changes to metamorphic rock

• Metamorphic rock changes to sedimentary rock

• Igneous rock changes to sedimentary rock

Which of the following examples is most likely to be classified as a sedimentary rock?

• Sandstone, which forms from sand and sand-sized grains of mineral, rock, or organic material that have been compacted and cemented together

• Gneiss, which forms when other rocks are exposed to intense heat and pressure underground at convergent plate boundaries

• Granite, which forms from the slow crystallization of magma below Earth's surface

• Obsidian, which forms when molten rock material cools so quickly that atoms are unable to arrange themselves into a crystalline structure.

_____________ Rock forms as a result of exposure to intense heat and pressure

• Sedimentary

• Metamorphic

• Igneous

• Quartzite

___________ Rock forms as a result of molten rock (lava or magma) cooling and becoming solid.

• Sedimentary

• Metamorphic

• Igneous

• Feldspar

• Basalt and granite are both igneous rocks.

• Basalt and granite are both sedimentary rocks.

• Basalt and granite are both metamorphic rocks.

• Basalt is metamorphic and granite is an igneous rocks.

___________ Rock forms as a result of layers of sediment becoming compacted and cemented.

• Sedimentary

• Metamorphic

• Labradorite

• Igneous
