Restless Earth - The Earth
- Crust
- Upper Mantle
- Lower Mantle
- Outer Core
- Inner Core
- Solid iron-nickel alloy due
to the immense pressure
- Hot as the surface of the sun
- Slowly growing as outer core cools
- Filled with low viscosity magma
which rises up into the mantle
- Convection currents here pull the
plates apart
- Still solid
rock but
in the
transition
stage
- Thin in comparison to
diameter of the Earth
- Continental and oceanic
plates move around the
Earth
- Oceanic plates are lighter but over 30km thick
- Continental plates are denser but only 5km thick
- Lithosphere
- Asthenosphere
- Mesosphere
- Viscous magma layer between
the asthenosphere and the
outer core
- Very viscous layer that sits
below the lithosphere
- Includes the crust and the
top-most part of the upper mantle
