Boundary Types
Describe the movement of Divergent Plates
Dividing, separating, drifting apart.
The current that pushes hot magma to the surface and allows the cooler magma to sink.
Convection current.
What plate boundary forms MOUNTAINS?
convergent
What is the theory of Continental Drift?
The continents are moving apart slowly.
Warm up time is....
Convergent plates are moving in what way?
Subduction is when
old crust is destroyed by the magma
Slip plate boundaries cause this natural disaster.
____________
Earthquakes
How does the continent puzzle support this theory?
The continents look like they fit together, like a puzzle would.
We should come to school with our devices... and if not what happens?
CHARGED... or you borrow a charger with an email home.
Slip plates are doing what?
sliding against each other.
TRUE or FALSE
The hotter the magma, the less dense it becomes.false

How is the new crust formed?
The magma that pushes through the Mid-ocean ridge hardens as it comes in contact with the water.
Volcanoes are formed through ___________.
Convergence.
Western Antarctica and South America share a chain of this earth feature. Bonus if you remember the name of them.
Andes Mountains
Miss Allen's biggest pet peeve is ____________. what should we do instead?
Talking over each other. We should raise our hands and wait for our turn instead.
