Exploring the Rock Cycle Quiz

What type of rock is formed from the cooling and solidification of magma or lava?

• Sedimentary

• Igneous

• Metamorphic

• Fossil

Which process is responsible for the formation of sedimentary rocks?

• Melting

• Cooling

• Compaction and cementation

• Evaporation

What is the main difference between sedimentary and metamorphic rocks?

• Sedimentary rocks form from magma, while metamorphic rocks form from sediments.

• Sedimentary rocks form from sediments, while metamorphic rocks form from existing rocks changed by heat and pressure.

• Both are formed by cooling lava.

• Both are formed by evaporation.

Which of the following best describes the process of metamorphism?

• Rocks breaking into smaller pieces

• Rocks melting into magma

• Rocks changing due to heat and pressure

• Rocks cooling from lava

Which stage of the rock cycle involves the breakdown of rocks into smaller pieces by wind, water, or ice?

• Melting

• Weathering

• Cementation

• Cooling

Explain how a sedimentary rock can become a metamorphic rock.

• By melting and cooling

• By being buried and subjected to heat and pressure

• By breaking into sediments

• By evaporating

A student finds a rock with visible layers and some fossil imprints. Using evidence, which type of rock is it most likely to be?

• Igneous

• Sedimentary

• Metamorphic

• Volcanic glass

Given the following scenario: Magma cools and forms granite. Over time, granite is broken down into sediments, which are compacted into sandstone. Later, sandstone is buried deep underground and exposed to heat and pressure, becoming quartzite. Which sequence correctly illustrates the rock cycle processes involved?

• Melting → Cooling → Weathering → Compaction → Heat and Pressure

• Cooling → Weathering and Erosion → Compaction and Cementation → Heat and Pressure

• Weathering → Melting → Cooling → Compaction

• Compaction → Melting → Cooling → Weathering
