On fault lines all over the world.
Where do earthquakes occur?
200
A boundary that is moving away from each plate.

By continents drifting apart.

Alfred Wegener
Who proposed the idea of pangea and continental drift?
400
2 trips
How many trips did he take to Greenland for his research?
400
The less dense plate goes under the more dense plate.
How is a subduction zone made?
400
transform boundary
What type of boundary do earthquakes occur on?
400
On the edge of continental plates.
Where are plate boundaries?
400
same type of rock on both sides of the atlantic ocean.
what was the evidence for the theory?
500
Greenland
Where did he die?
500
A boundary where plates slide against each other.
What is a transform boundary.
500
Volcanos erupting, land slides, meteor impacts
What are other ways earthquakes are caused?
500
volcanos.
What can convergent boundaries form?
500
Fossils, and continents fit together like puzzle pieces.
