Unit 5 Rock Cycle Study Guide

Igneous rocks can be which of the following? (Choose 3)

• intrusive

• extrusive

• formed from magma

• contain fossils

• change when pressure is applied

Which type of rock is formed at location C?

• Igneous

• Metamorphic

• Fossils

• Sedimentary

Igneous rocks are formed from ___________.

• Magma

• Sediment

• Ash

• Heat and Pressure

What would be the best description for how the canyon in the picture was created?

• weathering and erosion

• lava flowing

• heat and pressure

• no one knows

A volcanic rock formation is exposed to wind, rain, freezing and thawing over millions of years. The sediments from these form new rocks with multiple layers. Which formation of rock has occurred?

• metamorphic rock to igneous rock

• metamorphic rock to sedimentary rock

• sedimentary rock to metamorphic

• igneous rock to sedimentary rock

Which of the following scenarios could explain how volcanic and sedimentary rock can become metamorphic rock?

• A volcanic eruption sends lava down the side of a mountain into the ocean

• One tectonic plate is forced under another creating new rock

• Water erodes these rock forms depositing the sediment into the ocean

• Hot magma cools under ground very slowly.

Shale is formed when many layers of silt and clay are compacted. If shale is put under intense heat and pressure slate is created.Which type of change occurs when shale turns to slate?

• igneous rock to sedimentary rock

• metamorphic rock into sedimentary rock

• sedimentary rock into igneous rock

• sedimentary rock to metamorphic rock

A rock cycle diagram is shown below. What process is occurring at B?

• Erosion is occurring

• Weathering is occurring

• Heat and pressure are being applied

• Magma is forming deep inside the Earth

Kayla was able to determine that three out of the four rocks shown below are igneous. Which three rocks should Kayla choose as igneous?

• A

• B

• C

• D

How are metamorphic and igneous rocks similar?

• Heat and pressure turn them into sedimentary rocks

• Heat and pressure turn them into igneous rocks

• Weathering and erosion turn them into sedimentary rocks

• Weathering and erosion turn them into metamorphic rocks
