Unit 3 Study Guide

What determines whether a rock is sedimentary, metamorphic, or igneous?

• where it's found

• where it's formed

• how it's formed

• when it's formed

How long does it take for rock formations to transform?

• days

• months

• years

• millions of years

How can sedimentary rock transform into igneous rock?

• it is not possible

• by melting into magma, then cooling

• by weathering and eroding, then being deposited

• by being exposed to heat and pressure

How is rock weathered into sediment?

• wind and rain breaks it into small pieces

• the sun causes the rock to dry out and crumble

• only earthquakes and tsunamis that are strong enough break the rocks apart

• rays from the sun blast the rock apart

What kind of energy causes sediment to form?

• energy from Earth's core

• energy from the Sun

• energy from boiling water

• energy from wind

How can igneous rock transform into sedimentary rock?

• by melting into magma, then cooling

• by being blasted apart by the Sun's rays, then being compacted and cemented together

• by being weathered into sediment, then cemented and compacted together

• by being exposed to heat and pressure

How is metamorphic rock formed?

• it is made from magma that cooled

• it broke into sediment and then compacted

• it was heated and put under pressure

• it is dug out of the bottom of Earth's crust

Which process is needed to form sedimentary rock from sediment?

• weathering and erosion

• heat and pressure

• compacting and cementation

• melting and cooling

Which process is needed to form metamorphic rock?

• weathering and erosion

• heat and pressure

• compacting and cementation

• melting and cooling

Which process is needed to form igneous rock?

• weathering and erosion

• heat and pressure

• compacting and cementation

• melting and cooling
