What's the difference between lava and magma?

Lava


Definition:

  • (n.) The melted rock ejected by a volcano from its top or fissured sides. It flows out in streams sometimes miles in length. It also issues from fissures in the earth's surface, and forms beds covering many square miles, as in the Northwestern United States.

Magma


Definition:
