Understanding the Rock Cycle

Which process involves the breaking down of rocks into smaller pieces?

• Cementation

• Melting

• Compaction

• Weathering

What sequence of processes leads to the formation of sedimentary rocks?

• Uplift, melting, solidifying

• Heat, pressure, uplift

• Weathering, erosion, deposition, compaction, cementation

• Melting, cooling, solidifying

What role does pressure play in the rock cycle?

• It is only involved in the formation of sedimentary rocks

• It helps in the melting of rocks

• It contributes to the formation of metamorphic rocks

• It decreases the temperature of magma

What type of rock is formed directly from magma?

• Mineral

• Sedimentary

• Metamorphic

• Igneous

Which type of igneous rock forms beneath the Earth's surface?

• Extrusive

• Intrusive

• Sedimentary

• Metamorphic

What does the term 'lithification' refer to in the rock cycle?

• Transformation under heat

• Compaction and cementation of sediments

• Formation of crystals

• Melting of rocks

Which rock type is formed by the cooling and solidification of lava on Earth's surface?

• Extrusive igneous

• Sedimentary

• Intrusive igneous

• Metamorphic

How can a metamorphic rock transform back into an igneous rock?

• Through deposition

• By undergoing lithification

• By melting due to intense heat

• Through erosion and sedimentation

How many different types of rocks are there?

• 1

• 2

• 3

What is the primary characteristic that distinguishes sedimentary rocks from other types of rocks?

• They are formed from magma

• They are formed from the accumulation of sediments

• They are formed under high pressure and temperature
