100
This is the name of the proposed "supercontinent" where all the earth's continents were once joined together.
What is Pangaea?
100
Seafloor Spreading occurs at what type of plate boundary?
What is a divergent boundary?
100

This is the outermost layer of the Earth.

What is the crust?

100
This type of plate boundary involves two plates moving apart from one another.
What is a divergent boundary?
100
These features are produced on earth when two continents collide.
What are mountains?
200
This is the meteorologist who first proposed the Theory of Continental Drift
Who is Alfred Wegener?
200
These features form as new crust rises to the surface during seafloor spreading
What are mid-ocean ridges?
200

This is where convection currents take place.

What is the mantle?

200
This type of plate boundary involves two plates moving toward each other.
What is a convergent boundary?
200

These features are produced on the coasts of continents where oceanic crust moves underneath the continent.

What are volcanoes?

300
This is how many years ago earth's "supercontinent" began to split apart.
What is 200-250 million years ago?
300
This ocean is currently growing in size due to seafloor spreading.
What is the Atlantic Ocean?
300

These are the two plates that collided to form Mt. Everest.

What is the India and Eurasian Plates?

300
This type of plate boundary involves one plate sliding past another plate.
What is a transform boundary?
300
These natural disasters occur when a sudden movement occurs along transform boundaries.
What are earthquakes?
400

What are the two pieces of evidence that supports the Theory of Continental Drift.

What are similar shapes of landforms, fossil evidence, glaciers, coal deposits, and seafloor spreading?

400

This is where the newer crust can be found.

Where is closer to the plate boundary?

400

This is where the the heat comes from to create convection currents.

What is the core?

400
This is the term for one plate being forced underneath another plate.
What is Subduction?
400

This is the name of landform where there are cracks in the crust due to a transform boundary earthquake.

What is a fault?

500

What was the name of the female scientist who discovered seafloor spreading?

Who is Marie Tharp?

500

This is the other piece of evidence of seafloor spreading.

What is changes in the Earth's magnetic fields?

500

These are the two types of crust found on earth.

What is continental crust and oceanic crust?

500
This is the term for the fracture created when one plate suddenly slides past another plate.
What is a fault?
500

These two features form in the ocean when one oceanic plate is forced below another oceanic plate

What are trenches and volcanic islands?
