Geological Features and Faults

The video tutorial covers Chapter 5 on earthquakes, focusing on different types of stress: tension, compression, and shearing. It explains how these stresses create geological features like mid-ocean ridges, Rift Valleys, and various types of faults, including normal, reverse, and strike-slip faults. The San Andreas Fault is highlighted as a prime example of a strike-slip fault. The tutorial also discusses oblique slip faults and geological features such as Horst and Graben. Finally, it covers geological folds, specifically syncline and anticline, with real-life examples and illustrations.

What type of stress is responsible for creating mid-ocean ridges?

• Shearing

• Tension

• Compression

• Bending

Which geological feature is typically formed by the subduction of an oceanic plate beneath a continental plate?

• Deep Ocean Trench

• Rift Valley

• Mid-ocean Ridge

• Plateau

In a normal fault, which direction does the hanging wall move?

• It remains stationary

• Sideways

• Downward

• Upward

What type of fault is the San Andreas Fault primarily considered?

• Strike-slip Fault

• Reverse Fault

• Normal Fault

• Oblique-slip Fault

Which type of fault involves horizontal movement along the fault line?

• Strike-slip Fault

• Reverse Fault

• Oblique-slip Fault

• Normal Fault

What is a Horst in geological terms?

• A type of volcanic mountain

• A valley formed by tension

• An uplifted block between two normal faults

• A fold in sedimentary layers

What type of stress leads to the formation of a Graben?

• Shearing

• Bending

• Tension

• Compression

Which geological feature is characterized by a downward fold?

• Anticline

• Horst

• Syncline

• Graben

What is the primary difference between a syncline and an anticline?

• Both are folds down

• Both are folds up

• Syncline is a fold down, anticline is a fold up

• Syncline is a fold up, anticline is a fold down

Which of the following is an example of a geological fold?

• Horst
