 * 1) The large landmass where all of the continents formed one land was called Pangaea.
 * 2) Initially, Pangaea split into 2 pieces of land called Laurasia and Gondwana.
 * 3) Mid-ocean ridges are underwater mountain chains that run through the Earth's Ocean Basins.
 * 4) Sea floor spreading is the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.
 * 5) A convergent boundary is where 2 tectonic plates collide.
 * 6) A divergent boundary is where 2 tectonic plates divide or separate.
 * 7) A transform boundary is where 2 tectonic plates slide past each other horizontally.
 * 8) A subduction boundary is where one tectonic plate slides under the other tectonic plate.
 * 9) Convection currents cause the oceanic lithosphere to move sideways.
 * 10) Compression is a type of stress that occurs when an object is squeezed.
 * 11) Tension is a type of stress that occurs when forces act to stretch an object.
 * 12) There are 3 types of faults: normal, reverse, and strike-slip.
 * 13) There are 3 basic types of mountains: Folded mountains, Fault-Block and Volcanic.
 * 14) An example of folded mountains would be the Appalachian Mountains.
 * 15) An example of fault-block mountains would be the Tetons in Wyoming.
 * 16) The edge of the Pacific plate is where a lot of valcanoes exist. Because of this, it is often referred to as the Ring of Fire.
