Plate Tectonics and Geological Features of Convergent Divergent and Transform Boundaries

The video explains three types of plate boundaries: convergent, divergent, and transform. Convergent boundaries involve plates moving towards each other, causing earthquakes, volcanoes, and trenches. Divergent boundaries occur when plates move apart, forming new crust and features like mid-ocean ridges. Transform boundaries involve plates sliding past each other, often causing earthquakes. Examples include the Nazca and South American plates, the Aleutian Islands, the Himalayan range, the mid-ocean ridge, the East African Rift Valley, and the San Andreas Fault.

What natural events are commonly associated with convergent plate boundaries?

• Earthquakes and volcanoes

• Hurricanes and tornadoes

• Floods and droughts

• Tsunamis and cyclones

Which type of convergent boundary involves the subduction of oceanic crust beneath continental crust?

• Transform

• Continental-continental

• Oceanic-continental

• Oceanic-oceanic

What geological feature is formed when oceanic lithosphere subducts beneath another oceanic lithosphere?

• Rift valleys

• Volcanic island arcs

• Mountain ranges

• Deep trenches

What happens when two continental plates collide?

• They cause seafloor spreading

• They form volcanic islands

• They create folded mountains

• One plate subducts under the other

What is the primary result of divergent plate boundaries?

• Formation of new crust

• Creation of deep trenches

• Formation of mountain ranges

• Destruction of crust

Which geological feature is a result of oceanic-oceanic divergent boundaries?

• Volcanic arcs

• Deep ocean trenches

• Mid-ocean ridges

• Folded mountains

What is an example of a continental-continental divergent boundary?

• The Aleutian Islands

• The San Andreas Fault

• The East African Rift Valley

• The Andes Mountains

What is a characteristic of transform boundaries?

• They result in subduction zones

• They cause earthquakes

• They create new crust

• They form volcanic mountains

Which fault is a well-known example of a transform boundary?

• The East African Rift

• The Himalayan Fault

• The San Andreas Fault

• The Mid-Atlantic Ridge

What is the main difference between convergent and divergent boundaries?

• Convergent boundaries involve plates moving apart, while divergent boundaries involve plates colliding.

• Convergent boundaries are associated with earthquakes, while divergent boundaries are not.

• Convergent boundaries create new crust, while divergent boundaries destroy it.

• Convergent boundaries involve plates colliding, while divergent boundaries involve plates moving apart.
