Convergent
In this type of boundary, plates are moving towards each other.
Convergent plate boundaries
What direction do the plates move in divergent boundries?
Away from each other
What direction are the plates moving in Transform boundries?
Past each other
Who came up with the idea of continental drifting?
Alfred Wegner
Name the chemical layers of the earth
Crust, mantle, and core
What land form is created when oceanic crust + oceanic crust meet?
What is an example of divergent boundary's? (In the water)
Mid Atlantic ridge
What do transform boundary's cause?
Earthquakes and faults
How long ago did Pangea exist?
245 million years ago
Name the physical layers of the earth
Lithosphere, Asthenosphere, Mesosphere, Outercore, Innercore
What is an example of continent and continent crust colliding?
Andes Mouintains
What is an example of divergent boundary's? (out of the water)
Rift valley
What is an example of transform boundary's?
San Andres fault
Why did the people who thought the continents drifted use parts of Africa, India and, South America as proof of Pangea?
Because there was proof that there used to be glaciers there at some point, which means that when Pangea existed they would've been closer to the South Pole.
The crust
When one crust goes under another how do you know which one will go under?
The more dense crust will go under the other crust
Divergent plate boundaries create this:
Rifts
What is the direction of movement?
Slide
What was the main reason people didn't believe the person who came up with continental drifting at first?
At the time there was no proof of what was making the continents moved.
Who created the idea of continental drifting?
Alfred Wegner
What land form is created when continental crust and continental crust collide?
Mountains are created
Yes
Pop Question! What elements is the innercore made of?
Iron and nickle
What were the pieces of land called after it broke off from Pangea?
Laurasia and Gondwana
What causes the tectonic plates to move?
The magma in the mantle moving causes the tectonic plates to move.
