Tectonic Plate Theory

A major geological event that occurs when continental plates of equal density converge, resulting in mountain chains

• mountain building

• earthquakes

• fault lines

• spreading ridges

This occurs when two tectonic plates move away from each other

• San Andreas Fault

• spreading ridges

• convergent boundary

• divergent boundary

These are formed from new crustal material

at diverging oceanic plate boundaries

• mountains

• spreading ridges

• transform boundary

• ocean trenches

This occurs when two tectonic plates slide past each other (the San Andreas Fault in California is a famous example)

• Pacific Plate

• convergent boundary

• fault line

• transform boundary

A major geological event that occurs when plates shift suddenly and release stored energy; frequent occurrences along all types of plate boundaries

• earthquake

• tidal wave

• volcanic eruption

• meteor

Density of plates is:

• easily breakable

• constantly shifting

• the amount of matter in a given space or volume

• thinner in ocean crust

An area of oceanic crust covered by seawater and surrounded by areas of continental crust is called

• crustal rock material

• transform boundary

• divergent boundary

• ocean basin

Oceanic crust is

• thick and porous

• sandy and thin

• thin and dense

• thick and dense

Continental crust is

• thin and sandy

• dense and thin

• thick and less dense

• rough and dense
