Exploring The Rock Cycle

What defines a cycle in the context of the rock cycle?

• A one-time geological event

• A human-made process

• An unpredictable natural event

• A process that repeats indefinitely

What is the first step in forming igneous rocks?

• Application of pressure

• Erosion of rock material

• Compaction of sediments

• Melting rock into magma

Which rock type can be formed by the cooling and solidification of magma?

• Sedimentary

• All rock types

• Igneous

• Metamorphic

What follows the deposition and burial of sediments in sedimentary rock formation?

• Melting into magma

• Compaction and cementation

• Subduction

• Crystallization

What is the role of erosion in the rock cycle?

• It compacts sediments into rock

• It heats the rocks

• It solidifies magma

• It breaks down rocks into smaller particles

Which process can transform a metamorphic rock into an igneous rock?

• Erosion

• Compaction

• Melting

• Weathering

What is required for the formation of metamorphic rocks?

• Deposition of sediments

• Intense heat and pressure

• Solidification of magma

• Erosion and weathering

How do igneous rocks transform into metamorphic rocks?

• By undergoing intense heat and pressure

• By melting into magma

• Through deposition and burial

• Through uplift and erosion

What happens to metamorphic rocks during more intense stages of metamorphism?

• They break down into sediments

• They melt into magma

• They transform into sedimentary rocks

• They undergo further changes in structure

How can sedimentary rocks transform back into sedimentary rocks?

• All of the above

• By uplift, weathering, erosion, and cementation

• By undergoing heat and pressure

• Through melting and solidification
