100
The most dense crust between Oceanic and Continental.
What is Oceanic crust?
100
The fossils of a plant have been found in rocks on South America, Africa, India, Australia and Antarctica.
What is fossil evidence of Continental drift.
100
In water warmer water moves to the top and cooler water moves to the bottom.
What is Convection?
100
Molten rock stuck underground.
What is Magma?
100
The type of seismic wave that usually arrives first.
What is the P wave?
200
The liquid like layer that flows.
What is the Asthenosphere?
200
Sound being sent from a ship to the ocean floor that bounces off the ocean floor helping to find the distance to the sea floor.
What is Sonar?
200
Places where the Oceanic crust goes under either oceanic or continental crust.

Three recording stations are needed for this.
What is to find the epicenter?
300
Split up into the Lithosphere, Asthenosphere and Upper/Lower mantle.
What is the Mantle?
300
Reasoning behind the ages of rocks being the same at the same distance on each side from the mid ocean ridge.
What is sea floor spreading?
300
Where Oceanic crust moves away from Mid Oceanic Ridges.
What is Sea floor spreading?
300
Rocks that cool slowly after they reach the surface.
What is course rocks?

What is he could not explain how the continents moved?
400
Where high temperature plumes of magma rise to the surface.
What is Mantle plumes?
400
Rocks with two cooling periods.
What is porphyritic rocks?
400
Wave that moves across the surface like ripples on water.
What is L wave?
500
The thicker type of crust that is made of Granites and less dense rocks.
What is Continental crust?
500
The reasoning of why the Appellation mountains and the Caledonian mountains would seem continuous if North America and Europe were next to each other.
What is Rock evidence of Continental drift?
500
The feature that mantle plumes can create.
What is Volcanos?
