the crust
Outer layer

5-100 km thick

2 types of crust

Oceanic (very dense, made of basalt)

Continental (less dense, made of granite)

The Crust
the mantle
Middle layer

Very thick layer

The Mantle
the core
The Core
  • Made mostly of iron
  • 1/3 of the earth’s mass
  • Very hot
physical structure of the earth 5 layers
Physical Structure of the Earth(5 Layers)
  • Lithosphere - rigid outer layer (crust)
  • Asthenosphere - solid rock that flows slowly (like hot asphalt)
  • Mesosphere - middle layer
  • Outer Core - liquid layer
  • Inner Core - solid, very dense
tectonic plates
Tectonic Plates
  • Earth’s crust is broken into about 19 pieces
  • These plates move on top of the asthenosphere
