Rock Transformation Processes

The video explains the rock cycle, detailing how rocks transform between igneous, sedimentary, and metamorphic forms. It covers the processes of weathering, erosion, compaction, cementation, heat, pressure, melting, cooling, and crystallization. The video also discusses the reverse processes and recycling of rocks within the cycle.

What process is responsible for turning igneous rocks into sediments?

• Compaction and cementation

• Melting

• Weathering and erosion

• Heat and pressure

How do sediments become sedimentary rocks?

• Via compaction and cementation

• Undergoing heat and pressure

• By cooling and crystallizing

• Through melting

What is required to transform a sedimentary rock into a metamorphic rock?

• Weathering and erosion

• Heat and pressure

• Melting

• Cooling and crystallization

What must happen to a metamorphic rock to form magma?

• It must undergo compaction

• It must be cemented

• It must be weathered and eroded

• It must melt

What process turns magma into igneous rock?

• Cooling and crystallization

• Weathering

• Erosion

• Compaction

How can an igneous rock become a metamorphic rock?

• By melting

• By compaction and cementation

• Through weathering and erosion

• Undergoing heat and pressure

What is the first step in transforming a metamorphic rock into sediments?

• Melting

• Weathering and erosion

• Cooling and crystallization

• Compaction

What must happen to a sedimentary rock to form magma?

• It must be cemented

• It must undergo compaction

• It must melt

• It must be weathered and eroded

How can a metamorphic rock transform into another metamorphic rock?

• By melting

• By cooling and crystallization

• Through weathering and erosion

• Undergoing additional heat and pressure

What process allows a sedimentary rock to become another sedimentary rock?

• Cooling and crystallization

• Heat and pressure

• Weathering and erosion followed by compaction

• Melting
