Plate Tectonics and Geological Features

The video tutorial on plate tectonics covers the types of plate boundaries, geologic features resulting from plate movements, and evidence of crustal movement. It explains divergent, convergent, and transform boundaries, highlighting examples like the Mid-Atlantic Ridge, Andes Mountains, and San Andreas Fault. The tutorial also discusses subduction zones, trenches, hotspots, and mid-ocean ridges, emphasizing the processes of sea floor spreading and volcanic formation.

What are the three types of plate boundaries?

• Divergent, Convergent, Transform

• Convergent, Subduction, Transform

• Divergent, Subduction, Transform

• Convergent, Divergent, Subduction

What is the lithosphere composed of?

• Only oceanic crust

• Only continental crust

• Both oceanic and continental crust

• Neither oceanic nor continental crust

Which geological feature is formed at divergent boundaries?

• Trenches

• Mid-ocean ridges

• Volcanic arcs

• Mountain ranges

What happens when oceanic and continental plates converge?

• The oceanic plate slides over the continental plate

• The continental plate slides over the oceanic plate

• Both plates remain stationary

• The oceanic plate is subducted under the continental plate

Which of the following is an example of a transform boundary?

• Andes Mountains

• Himalayan Mountains

• San Andreas Fault

• Mid-Atlantic Ridge

What is a hotspot?

• A zone of subduction

• A zone where plates are moving apart

• A zone of rising magma

• A zone where plates are colliding

Where can hotspots be found?

• Iceland, Hawaii, Galapagos

• Japan, Indonesia, Andes

• Himalayas, Andes, San Andreas

• Mid-Atlantic Ridge, Iceland, Japan

What process occurs at mid-ocean ridges?

• Volcanic eruption

• Mountain formation

• Sea-floor spreading

• Subduction

How can scientists date the creation of ocean floor?

• By measuring the depth of the ocean

• By analyzing the type of rock

• By examining the distance from the mid-ocean ridge

• By studying the temperature of the ocean

What is the relationship between ridges and trenches?

• Ridges create new ocean floor, trenches destroy old ocean floor

• Ridges and trenches are unrelated

• Trenches create new ocean floor, ridges destroy old ocean floor

• Ridges are formed by subduction, trenches by divergence
