Earth's Interior
Scientists who studies forces that make and shape earth.
Geologists
The place where two plates move apart.
Divergent boundary.
Three types of stress that act upon rocks changing shape or volume.
Shearing, tension, compression.
Name given to magma once it reaches the surface.
Lava.
Destructive.
Two things that increase by degree the deeper into the earth one measures.
The name Wegener gave the super continent, which means "all lands."
Pangaea
A break in Earth's crust where slabs of crust move past each other.
Fault
Major volcanic belt located in the Pacific Ocean.
Ring of Fire.

Three types of heat transfer.
Convection, conduction, and radiation.

Strike-slip, normal, reverse, thrust.
The long tube in the ground that connects the magma chamber to Earth's surface.
Pipe.
The measure of how much mass there is in the volume of a substance.
Density.
Originator of the theory of the Continental Drift.
Wegener
Process where new material is continually being added to the ocean floor.
Sea floor spreading.
The names and descriptions of two types of folds.
Anticline: domelike
Syncline: basinlike
The more of this material in magma, the thicker it is.
Silica.
Method that rates the size of seismic waves.
Richter scale.
Longest chain of mountains in the world.
Mid-ocean ridge
Deep underwater canyons that the ocean floor plunges into.
Deep ocean trenches.
Name and description of each of the 3 types of seismic waves.
P: Primary
S: Secondary
L: Surface
Type of volcano that forms when lava flows alternate with explosive eruptions.
Composite
Three stages of activity that describe volcanoes.
Active, dormant, extinct.
