Work in progress

We have so many entries on Chemistry and Physics, yet the Geology ones are few and far between. So I think I'll be ambitious and fill in a few gaps.

The driving force

• Structure of the Earth (mantle circulation - need this to explain plumes)
• Plate tectonics (link to A884469 - Plate Tectonics)
• Spreading ridges and subduction zones

Locations

Spreading ridges

• Examples - Mid Atlantic Ridge...
• Find a speed of spreading?
• Mechanism of eruption
• Depth of crust
• MORB
• Discovery - matching up Africa and South America

Subduction zones

Oceanic hotspots

Continental hotspots

• Yellowstone!

Famous eruptions

Volcanoes on other planets

Useful links/information

• Earth
• Earthquakes (this needs updating, too...)
• Yellowstone! And supervolcanoes!¹
• Plate tectonics²
• Tambora eruption
• The rock cycle

Hmm, this may actually work better as a Uni project than as a single entry. This would be hard to split up into five entries, though... Three seems more sensible, which wouldn't be enough.
