The outermost layer of the Earth.
Crust
The rigid outer part of the Earth, consisting of the crust and the upper mantle.
Lithosphere
It is below the lithosphere, relatively low resistance to plastic flow and convection is thought to occur.
Asthenosphere
The innermost part of the Earth which is a solid ball consisting of iron and nickel.
Inner Core
A fluid layer of the Earth, consisting of iron and nickel.
Outer Core
When two tectonic plates collide.
Convergent
When two tectonic plates pull away from eachother.
Divergent
When two tectonic plates slide past eachother.
Transform
When convergent plate boundaries collide causing one plate to go underneath the other.
Subduction
This type of land forms when convergent plates collide.
Mountains
This type of land can form underwater and on land when divergent plates pull apart.
Ridges
This occurs when transform boundaries slide against one another.
Earthquakes
This happens when two oceanic plates diverge.
Seafloor Spreading
A meteorologist and geologist that proposed the Continental Drift Theory.
Wegener
The study of the shapes and features of Earth's surface.
Topography
Shows 3D shapes and elevations of an area of land in 2D.
Topography Map
Lines that connect places on a topography map that are all at the same elevation.
Contour Line
A deep depression of the seafloor caused by the subduction of one plate under another.
Trench
A crack in the Earth's crust where rocks slide past one another.
Fault
The supercontinent that had once included all of the Earth's land mass.
Pangaea
