Continental Drift
These same evidences were found on multiple continents including Antarctica.
Fossils
This layer in the earth is a liquid.
Outer Core
These two occurrences help us see the outline of the plates.
Volcanoes and Earthquakes
This is the stage of a large star after the Red Giant stage.
Supernova
This is the instrument that was used to see the ocean floor in the 1940s
Sonar
This person started the idea of continental drift.
Alfred Wegener
This layer is plastic like layer that can flow.
Asthenosphere
This is about how fast plates move.
Fingernail growth
This is the lifespan of a star the size of our sun.
10 billion years
This is what happens near mid ocean ridges when the magnetic poles shift.
Magnetic striping
Alfred Wegener found this piece of evidence that looked like it was coming out of the ocean onto land. It didn't make much sense to him without the land all being together.
Glaciers
This layer is stony and brittle
Lithosphere
This is what is under Hawaii and helped form it.
Mantle plume
This is the final stage of our sun.
White dwarf
This is what happens to the iron particles in a rock when it cools.
It aligns towards the magnetic poles
This piece of evidence matched up the western united states with northern Africa and Europe.
Mountain Ranges
These are the 2 reasons the inner earth is so hot.
Radioactive decay, heat from formation
The oldest oceanic crust is near this.
This is the process through which the planets in our solar system formed.
Accretion
These are the evidences that Alfred Wegener presented to other scientists.
Mountain Ranges, Fossils, Glaciers, Continents pieced together
This process moves the plates.
Convection in the mantle
This type of plate boundary forms a mid ocean ridge.
Divergent
This is the name of the theory for star and solar system formation.
