Geological Processes and Mountain Formation

The video covers mountain building, focusing on the role of plate tectonics at convergent boundaries. It explains the formation of mountain belts, contrasting active and passive continental margins. The video discusses stress types affecting rocks, leading to deformation, and details different faults and joints. It concludes with an overview of mountain types, including folded, dome, and fault block mountains.

What is the primary geological process responsible for the formation of the Himalayas?

• Passive continental margins

• Transform plate boundaries

• Divergent plate boundaries

• Convergent plate boundaries

Which type of continental margin is associated with significant volcanic activity?

• Transform boundaries

• Compression

• Torsion

Which type of fault is characterized by the hanging wall moving downward relative to the footwall?

• Reverse fault

• Strike-slip fault

• Normal fault

• Thrust fault

What is an anticline in geological terms?

• An upfold in rock layers

• A downfold in rock layers

• A type of mountain

• A type of fault

Which type of fault is associated with horizontal movement along the fault plane?

• Thrust fault
