Earth`s Layers
Continental Drift Theory
Plates and Boundaries
Plates and Boundaries continued...
100
These are the 4 zones that Earth is broken into.
What are the crust, the mantle, the inner core, and the outer core?
100
The theory that all continents are pieces of Pangea that have drifted apart.
What is the continental drift theory?
100
Various sizes of crust and mantle and move around the atmosphere very slowly. These are the cause of earthquakes and volcanoes.
What are tectonic plates?
100
This happens when plates collide and an ocean trench causes the lithosphere to be subducted.
What is a convergent boundary?
200
In this layer, weather happens.
What is the Atmosphere?
200
This scientist proposed the continental drift theory.
Who is Alfred Wegener?
200
These are where earthquakes and volcanoes happen.
What are plate boundaries?
200
This is a type of convergent plate boundary happens when dancer oceanic slab sinks into the athenosphere.
What is Oceanic-Continental?
300
We live on this layer.
What happens on the crust?
300
This theory was created by Alfred Wgener.
What is The Continental Drift Theory?
300
This is when two plates move apart. Also A hit book series.
What are Divergent plate boundaries?
300
A thin layer, broken up into plates. It covers the Earth.
What is the crust?
400
This is the hottest layer, but it is solid metal.
What is the inner core?
400
Pangea existed in this many years ago.
What is 250 million years ?
400
This is what a Divergent plate boundary does.
What causes two plate to come apart and mantle to come up to create seafloor
400
This is when two OCEANIC slabs collide and one goes underneath the other.
What is oceanic oceanic?
500
This extends about half-way to the core. It is a solid, but acts as a liquid.
What is the mantle?
500
The Continental Drift Theory did not explain this.
What is how the continents moved?
500
Names three major plates.
What are the North American plate the South American plate the Eurasian plate the Indo Australian plate the African plate or the Antarctica plate?
500
This is way too plates collide and one goes under.
What is subduction?
