_______the thin outer later of the Earth where we live.Variesin thickness from around 5km thick (in the ocean floor) to around 70km thick on land.
CRust

The 2nd layer of the Earth is called the M__________. The M______ is much thicker than the crust at almost 3000km deep. It's made up of slightly different silicate rocks with more magnesium and iron.
Mantle
601
The I____C___ is so deep within the earth that it's under immense pressure. So much pressure that, even though it is so hot, it is solid. The i___c____ is the hottest part of the Earth, and, at over 5000 degrees C, is about as hot as the surface of the sun.
Inner Core
601
The Earth's O---- C----- is made up of iron and nickel and is very hot (4400 to 5000+ degrees C). This is so hot that the iron and nickel metals are liquid! The outer core is very important to earth as it creates something called a magnetic field. The magnetic field the outer core creates goes way out in to space and makes a protective barrier around the earth that shields us from the sun's damaging solar wind.
