Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle

What is plate tectonic theory?
What causes tectonic plates move?
Plates at our planet's surface
move because of the intense
heat in the Earth's core that
causes molten rock in the
mantle layer to move. It
moves in a pattern called a
convection cell that forms
when warm material rises,
cools, and eventually sink
down. As the cooled material
sinks down, it is warmed and
rises again
Heat is produced in
the core that produces
convection in the
mantle. This convection
causes the plate to
move around.
