Hence, the difference between lava and magma pertains to their location. Origin of the Term The term magma is derived from an ancient Greek word meaning ‘’ thick unguent ” which is used to refer to viscous substances such as ointments or lubricants. When magma cools inside the Earth, it has large minerals, because it cools slowly. However, deaths and injuries have been reported because they moved near the flow or their escape path was cut off or rarely because the lava flow moves too fast. The formation of magma and lava results from rock superheating to a point where it becomes viscous. The difference between lava and magma is that lava is the hot mixture of gases and molten rocks that come out of the volcano whereas magma is the molten rock material deep inside earth’s crust. Casualties of lavas are rare because flows are typically slow enough to give time for people and animals to move away although this depends on the viscosity of particular lava. Magma's temperatures range between 700 to 1600 degrees Celsius. Lava occurs above the Earth’s surface, and magma below. Plates can either move at the transform, divergent, or convergent boundaries.
