Plate Tectonic Notes

the three types of movement

collide, move apart and slide past

the three boundraies

convergent, divergent and transform

plasticity

is the condition of a solid that allows it to flow like plastic putty.

Convection

is the movement by which hot material rises and cooler material sinks

oceanic

ocean floors

transform can cause

earthquakes and tsunami

continental

landmass

Can tectonic plates affect the US

yes, an example is in California the San andreas fault is cause by a transform boundary.

Are tectonic plates large or small?

both; there are 7 or 8 major plates and several minor plates.

lithosphere

made up of the Earth's Crust and the uppermost part of the mantle. It is cool and rigid.

Pangaea

means all the Earth (alfred wegener)

molten

melt or liquify

mantle is known as..

molten rock

divergent can cause

mountains, sea-floor spreading, volcanoes, midocean rides.

convergent can cause

mountains, volcanoes, subduction, earthquakes, and trenches.

convecton currents

move in circular motions
