How do fossils present evidence for continental drift?
What is similar species are found in fossils in different continents
100
What was Pangaea?
a giant supercontinent made up of the current continent 200 million years ago
100
What is the ring of fire
A zone of frequent earthquakes and volcano eruptions
100
What is a plate in geographical terms?
A large, rigid slab of solid rock
100
Where do convergent boundaries occur?
between oceanic and continental boundaries, oceanic and oceanic boundaries, and continental and continental boundaries
200
Who First proposed the theory of continental Drift?
Alfred Wegener
200

What Evidence do we have that the continents once fit together?

Mountain features and fossils of animals and plants. 

200
Where is the ring of fire located in the united states
on the west coast (California)
200
How to the plates move?
Through the mantels convection currents
200
Where do divergent boundaries exist?
where plates are spreading apart and new crust is formed
300
What is the theory of plate tectonics?
Parts of the Earth's crust slowly drift atop a liquid core.
300
How did Pangaea turn into the continents that we have today
Continental Drift
300
Which part of the united states has the most earthquakes according to the ring of fire
the West coast
300

What layer do the convection currents move in?

The mantle

300

What are the 3 types of plate boundaries?

Divergent, convergent, and Transform, 

400
How is Pangea evidence for continental drift?
Continents fit together like puzzle pieces
400
Where did Africa and North America Connect in Pangaea?
On the southwest coast of Africa
400
The ring of fire results in what?
earthquakes and volcano eruptions
400
The convection currents in the mantel also move what?
The tectonic plates
400
What type of boundary exists at the mid atlantic ridge?
Divergent boundary
500
How does distinctive rock strata support continental drift theory?
Geological structures of the rocks on different continents are identical to each other.
500

Why did pangea break apart?

Plate tectonics allow for colliding and drifting of earths plates. 

500
How does the ring of fire relate to Plate tectonics?
The ring of fire is located at the boundaries of plates
