Intro to Continental Drift and Tyes of boundaries

When two tectonic plates slide past each other.

• transform boundaries
• divergent boundaries
• convergent boundaries

What type of currents help move the tectonic plates?

• convection
• conduction
• thermal

Huge pieces of crust/lithosphere that slowly move on the mantle and are rigid and solid.

• crustal moving plates
• tectonic plates
• convergent plates

Which plate boundary consists of plates moving toward each other?

• transform
• convergent
• divergent

When one plate goes under the other, it is called:

example: oceanic crust under continental crust

• divergent
• subduction
• transform

When two plates move away from each other-

• convergent boundaries
• divergent boundaries
• transform boundaries

Continental crust is best described as:

• thick and less dense
• thin and less dense
• thick and most dense

Oceanic crust is thinner and more dense than continental crust.

• True
• False

Pangea is described as:

• the 7 continents today.
• Africa and South America
• how the earths plates were once one land mass.

An ocean basin/floor is formed when:

• two plates pull apart.
• one plate goes under the other.
• two plates come together.
