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
