10. FORMATION OF EARLY EARTH

11. EARTH’S STRUCTURE

12. CRUST TYPES Old thinking – these slabs of crust were static, unmoving and unchanging

13. CRUST IN MOTION New thinking – these slabs of crust were in motion

14. EARLY EVIDENCE OF CONTINENTAL DRIFT

15. CONTINENTAL DRIFT THEORY Theory originally failed because no one could propose HOW IT WORKED

16. SONAR (1950s) MAP OF BASINS

17. MID-OCEAN RIDGE SYSTEM Under water volcanoes and new crust forming Largest geologic feature on the planet

18. CONTINENTAL DRIFT THEORY Theory accepted because CONVECTION was proposed as the MECHANISM of PLATE TECTONICS http://www.absorblearning.com/media/attachment.action?quick=12p&att=2775
