Plate boundary that has two plates moving AWAY from each other 

What is a divergent boundary?

100

People did not believe Alfred Wegener's theory of Continental drift because he could not prove THIS

What is the way the plate tectonics are able to move?

100

This scientist discovered seafloor spreading

Who is Harry Hess?

100

Result of two Continental plates colliding 

What is the formation of a mountain?

100

The reason the oceanic plate will sink when colliding with a continental plate 

What is density?

(Which is more dense?????)

200

Plate boundary that has two plates moving TOWARDS each other 

What is a convergent boundary?

200

Africa is warm now, but it used to be covered in ice 

The shape of the continents match 

The same fossil can be found on multiple continents 

The same mountain ranges can be found on different continents

Alfred Wegener was responsible for coming up with this theory 

What is continental drift?

300

Responsible for the movement of plate tectonics and how seafloor spreading is possible

This event is caused by a release of energy 

What are Earthquakes?

400

Subduction zones occur at this type of plate boundary
