Rocks and the Rock Cycle: Summing Up

The video tutorial explores the characteristics of the three main rock groups: igneous, metamorphic, and sedimentary. It delves into what defines a rock and examines the processes of weathering and erosion. The tutorial also investigates the rock cycle, highlighting how rocks transform over time. Finally, it encourages viewers to reflect on the dynamic nature of rocks and consider the various ways they may have changed.

Which of the following is NOT one of the three main rock groups?

• Metamorphic

• Igneous

• Crystalline

• Sedimentary

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

• Crystallization

• Sedimentation

• Weathering

• Metamorphism

How do weathering and erosion contribute to the rock cycle?

• They break down rocks and transport sediments.

• They cause rocks to melt.

• They form new rocks directly.

• They transform rocks into magma.

What is the rock cycle?

• A way to measure the age of rocks.

• A method to classify rocks by color.

• A cycle that describes the transformation of rocks over time.

• A process of forming only igneous rocks.

Why might you view rocks differently after learning about the rock cycle?

• Because rocks are always the same.

• Because rocks are only found in mountains.

• Because rocks are constantly changing form.

• Because rocks are not part of the Earth's crust.
