Tectonic Plates and Geological Features

The video covers the final day of a series on plate tectonics, focusing on plate movement and activity. It reviews convergent boundaries, explaining the three types: oceanic-continental, oceanic-oceanic, and continental-continental. The role of mantle convection currents in driving plate tectonics is discussed, along with the differences between passive and active plate margins. The video concludes with a summary of key concepts and a call to action for students to complete their notes.

What is the primary force that drives the movement of tectonic plates?

• Magnetic fields

• Convection currents

• Gravity

• Wind

Which type of convergent boundary involves oceanic crust meeting continental crust?

• Ocean-to-ocean

• Ocean-to-continent

• Transform

• Continent-to-continent

What geological feature is formed when oceanic crust subducts beneath continental crust?

• Plateaus

• Mid-ocean ridges

• Volcanic mountains

• Rift valleys

Which mountain range was formed by the collision of the Indo-Australian and Eurasian plates?

• Rocky Mountains

• Himalayan Mountains

• Alps

• Andes Mountains

What happens when two continental plates collide?

• They create a mountain range

• They form a transform boundary

• One plate subducts under the other

• They form a volcanic island

How do convection currents in the mantle affect tectonic plates?

• They move plates like a conveyor belt

• They create new crust

• They have no effect

• They cause plates to sink

What is the main difference between passive and active margins?

• Passive margins are found at transform boundaries

• Active margins have more volcanic activity

• Active margins are found at divergent boundaries

• Passive margins have more earthquakes

Which coast of the United States is considered an active margin?

• West Coast

• None of the above

• Gulf Coast

• East Coast

Why are there fewer earthquakes on the East Coast of the United States?

• It is a passive margin

• It is an active margin

• It is located on a transform boundary

• It is located on a convergent boundary

What type of boundary is associated with the creation of new crust?

• Convergent

• Divergent

• Transform

• Passive
