CRUST:CRUST:This is the thin, rocky

layer we think ofas the Earth´s surface

The crust comprises thecontinents and ocean

basins.

The crust has a variablethickness, being

35-70 Km in the continentsand 5-10 Km thick in

the ocean basins

MANTLE:MANTLE:This layer has semi-molten

rocks (partly melted). It actually flows

around the outer core,moving slowly

The mantle is about2900 Km thick andis separated into

the upper and lowermantle

THE OUTER CORE:THE OUTER CORE:The outer core is 2300 Kmthick. Here, the metals aremelted into a very hot liquid

THE INNER CORE:THE INNER CORE:The center of the Earth is

a solid ball about 6000 milesbelow the surface

exist

This hot liquid formsa layer that moves

around the inner core

The inner core is a solid ball made ofmostly two metals:two metals:

Iron and nickel

The lithosphereis divided into smallerpieces called tectonic

plates

Aluminum, Silicon and Oxygen

are common elementshere
