Boundaries
What are the 3 boundaries?
Transform boundary, Converge boundary, and Divergent boundary
Is continental drift a fact or a theory?
Who made up the theory of Pangea?
Alfred Wegner
How many layers to the Earth do we have ?
4. Inner core, outer core, mantle, crust
What is the theory of plate tectonics?
The theory is that the Earth's outer shell is divided into several plates that glide over the mantle; the plate's act like a hard and rigid shell compared to the Earth's mantle.
What happens in a divergent boundary? Give me an example.
The plates push away from each other.
Ridges.
Would Pangea be an example of continental drift?
Yes, because it shows that the continents have drifted over the years.
What type of continent was Pangea described as?
A supercontinent
What layer of the Earth, other then the crust, is solid?
How do the plates move?
The magma in the crust is moving in circular motion, making the plates move
What happens in a convergent boundary? Give me an example.
The plates move toward each other and collide.
Mountains.
What is the definition of continental drift?
The movement of Earth's continents across the earth's surface though geological time.
What was Europe and Asia called on Pangea?
Eurasia
Asthenosphere
An inch
What happens in a transform boundary? Give me an example.
The plates slide right past each other.
Earthquake
What is the theory of continental drift?
Why did Pangea break up?
A result of the movement of the Earth's tectonic plates and mantle convection.
Where does the mantle lie in the layers of the Earth?
In the middle of the layers of the Earth.
An example of plate tectonics.
Sea-floor spreading, mid-ocean ridge.
