Download Earth*s Layers

 6-70 km thick
 Very light; only 1% of Earth’s total mass
 Made up of rock
 Two types of crust
 Oceanic
 All of the ocean floors
 Continental
 Includes all continents and islands
 Thickest layer of Earth
 2900km thick
 64% of Earth’s mass
 Made of hot rock that is less dense than the
core
 870-4400 degrees Celsius
 Composed of liquid iron and nickel
 2300km thick
 Temperature and pressure here are lower
than in the inner core; that is why this layer is
a liquid
 4400-6100 degrees Celsius
 Solid layer of nickel and iron
 High temperature and pressure
 2400km in diameter
 7000-8000 degrees Celsius
 Earth’s crust and the top of the mantle
 Under the lithosphere
 Softer and hotter rock is located here
