- geological evidence for continental drift and plate tectonics:
- fit of the continents
- matching mountain chains
- glacial evidence
- biological evidence for continental drift and plate tectonics:
- fossil evidence
- palaeomagnetism and age of sea floor rocks also provides evidence for continental drift and plate tectonics
- structure of the earth:
- crust
- lithosphere
- asthenosphere
- mesosphere
- outer core
- inner core
- movement in the lithosphere and crust are caused by convection currents in the asthenosphere
