plate tectonics - Coggle Diagram
plate tectonics
4 layers
inner core
outer core
mantle
cust
ocianic
heavier
denser
continental
lighter less dense
convection currents
5000 degrrs core heats up the magma causin git to rise
magma spreads out creating friction with the plate
plates move apart
different types of bounders
constructive
plates pull apart forming a shield volcano
destructive
plates move together and oceanic crust sub ducts in to mantle and makes magma and forms a composite cone volcano
conservative
we don't get volcano's as 2 tectonic planes are moving next to each other at diffident speeds and they get snagged on one another and cause earthquakes
