Molten rock that has ben extruded from a subterranean reservour(magma chamber) onto the earth's surface. Many factors are involved in determining how forceful is ejected onto the surface, but the silica content seems to be a large determing factor. The higher the silica, the thicker the melt, which causes dissolved gases to become trapped inside crystal lattices within the melt, which means...KABOOM!!
Cascade volcanoes have a relatively high proportion of dissolved gases, which often makes their eruptions explosive

Lava is molten rock that originated from the mantle of a planet. Usually extracted through volcanos either on land or underneath water. Not to be confused with magma, which is molten rock that is still under the planets surface. Magma turns into lava after it erupts onto the surface. The core of Earth is often confused to be magma or rock, but most scientists believe it is iron or some other metal creating the magnetic poles.

1. (n) the hottest stuff on earth. seriously, liquid rock...are you kidding me? that shit's HOT...and liquid.
2. (n) type of material that spews forth from volcanoes at a moment's notice...or daily if you're kilauea.

hey guys, come over here and see this breakout where the pahoehoe lava is oozing.
lava is hot, and it rocks. (duh)

(n) Molten rock usually found in the earth's core or crust. Very fun to throw at people, if you can handle it!
