Exploring Types of Faults

The video tutorial explains the concept of faults in the Earth's crust, which are breaks where slabs of crust slip past each other. It covers three types of faults: normal faults caused by tension, reverse faults caused by compression, and strike-slip faults caused by shearing. The video also discusses how these faults can lead to the formation of mountains and valleys. Additionally, it explains the concept of folds in the Earth's crust, which occur due to compression, and provides examples of folded mountains like the Himalayas and the Alps.

What is a fault in geological terms?

• A type of valley

• A type of mountain

• A break in the crust where slabs of crust slip past one another

What type of force causes a normal fault?

• Tension

• Shearing

• Compression

• Bending

At which type of plate boundary do normal faults typically occur?

• Convergent boundaries

• Subduction zones

• Divergent boundaries

• Transform boundaries
