DI: Why do plates move?
Earth’s surface is broken up into 7 major tectonic plates.
plus some smaller (>5%)
These move about over time at about 2” per year.
How can they move?
The plates float on a gooey layer of the mantle that helps move them
The plates are are solid rock
Granite continents
basalt ocean floor
They float on the mantle because they are less dense.
The upper mantle is hot and soft magma - it flows slowly
like tooth paste
It slowly circulates - pushing the plates along with it.
The circulation is called convection.
Convection is the flow of a fluid as its density changes from heating and cooling.
Heating a fluid makes it less dense - so it rises.
Cooling a fluid makes it more dense - so it sinks.
Heating and cooling can cause a circulation current.
