Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one “hotspot” in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. picked by AutumnLotus 12 months ago

What would it take to jam a planet's tectonics? It seems that a huge rise in atmospheric temperatures would do the trick, causing continents to grind to a halt, mountains to stop growing and earthquakes to cease. On Earth, the motion of magma in the mantle pushes continental plates around on the surface, but if the magma became too hot and runny it would lose the grip needed to do this. picked by AutumnLotus 8 months ago

Could we hack geology? Could we use plate tectonics to re-direct whole island chains, color rocks, print cities out of magma, and build mountains where mountains have no right to be? Here are the Entropist's top five ways to change the surface of the earth. picked by tahafcuk 10 months ago

Oldoinyo Lengai, or 'Mountain of God' is located in Tanzania and is unique amongst volcanoes on Earth: its low-temperature natrocarbonatite lavas will often form eerie, surreal pinnacles and features that quickly turn to powder.
