Understanding the Rock Cycle

The video explains the rock cycle, detailing how igneous, metamorphic, and sedimentary rocks are interconnected through processes like weathering, erosion, compaction, cementation, and heat and pressure transformations. It highlights the cyclical nature of rock formation and transformation, emphasizing that rocks can change forms over millions of years. The video also provides resources for further learning.

What are the three main types of rocks involved in the rock cycle?

• Igneous, Sedimentary, and Metamorphic

• Igneous, Sedimentary, and Fossil

• Sedimentary, Mineral, and Igneous

• Metamorphic, Fossil, and Mineral

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

• Cementation

• Melting

• Compaction

• Weathering

How are sediments transported in the rock cycle?

• By earthquakes

• By animal activity

• By volcanic eruptions

• By wind or water

What is the process called when sediments are pressed together to form sedimentary rock?

• Compaction

• Weathering

• Melting

• Erosion

Under what conditions can sedimentary rock transform into metamorphic rock?

• Low pressure and high temperature

• Low pressure and low temperature

• High pressure and high temperature

• High pressure and low temperature

What can metamorphic rock turn into when it melts?

• Igneous rock

• Magma

• Sediment

• Fossil

What is the result when magma cools down?

• Metamorphic rock

• Mineral

• Sedimentary rock

• Igneous rock

What is a key characteristic of the rock cycle?

• It occurs over a few years

• It is a continuous cycle with many pathways

• It involves only sedimentary rocks

• It is a linear process

What is the term for the process where sediments are laid down in new locations?

• Cementation

• Weathering

• Erosion

• Deposition

Which type of rock can form both intrusive and extrusive varieties?

• Fossil

• Sedimentary

• Metamorphic

• Igneous
