7. The rocks and
continents of
the world belong
to the Earth's
crust. Beneath
that crust is
the Earth's
mantle. The
mantle is the
thick layer of
hot, solid rock
between the
crust and the
molten iron
core.

8. The inner core of the Earth, its
innermost hottest part . It is
believed to have a temperature similar
to the Sun's surface. It is believed
that this inner core is a solid ball of
mostly iron, and nickel.

outer core is made up of
super-heated liquid molten
lava. This lava is believed
to be mostly iron, and
nickel.
