The document summarizes key aspects of Earth's structure and systems: 1) It describes Earth's position in the solar system and its internal anatomy. 2) It discusses Earth's orbital changes, axial tilt variations, and their effects on climate and the distribution of daylight. 3) It outlines global wind circulation patterns, ocean currents, and how they redistribute heat and influence weather and climate.

- 19. What drives plate motions • Forces that drive plate motion – Slab-pull • Cold, dense slabs of subducted oceanic lithosphere pull the plate towards the subduction zone – Ridge-push • The higher elevation of spreading centers result in oceanic lithosphere wanting to move “downhill”, away from the ridge • Far less important than slab-pull – Mantle drag and plate resistance • Can act to increase or decrease plate motion
- 20. Mantle convection provides the primary drive for plate tectonics
- 22. What drives plate motions • Models of plate-mantle convection • Any model must be consistent with observed physical and chemical properties of the mantle • Horizontal movement of plates causes mantle upwelling • Models – Layering at 660 km – Explains why basalts erupted at mid-ocean ridges are different (more evolved, relatively shallow source) compared to those erupted at hot-spots (more primitive, deeper source). – We know that subducting slabs descend beneath 660 km
- 23. What drives plate motions • Whole-mantle convection – Would mix the entire mantle in the space of a few hundred million years, removing heterogeneities
- 24. What drives plate motions • Deep-layer model – “Lava lamp model” – Two layers swell and shrink in a complex fashion in response to heat from the Earth’s interior
