the mantle
what layer of the earth is made of liquid iron and nickel
outer core
what is the densest layer of the earth
inner core
What is it called when magma rises and then cools and sinks
convection
what is the inner core made out of
solid iron and nickel
where does convection happen
mantle
what causes tectonic plates to move
convection currents
what is the order of the layers least dense to most dense
crust, mantle, outer core, inner core
what is it called when the denser plate goes under the less dense plate
subduction
