Heat always flows from a warmers area to a
colder area

movement using radio signals

Heat with in Earth’s interior is transferred
primarily by convection

Lithosphere pieces
that move around on
top of the

The theory that
Earth’s lithosphere is
divided into moving
tectonic plates
Process of moving
layers of rock by
heating and cooling
