Mass or stream of molten rock that flows on the earth's surface under the influence of gravity; also, the solidified product of such a stream

A lava flow can be described as an outpouring of molten rock onto the Earth's surface forming a river or sheet.

Lava flows are masses of molten (liquid) rock that pour onto the Earth's surface during an eruption. Moving lava and the resulting solidified deposit are referred to as lava flows.

Stream of lava flowing from a volcanic vent.

Lava that oozes, like syrup, from the top of a volcano, down its sides, and onto the ground. Lava flows are formed by volcanoes like those of the Hawaiian Islands that do not have violent, explosive eruptions.

Lava which is outpoured in a flow on the land from a vent or fissure. Examples of lava flows include aa and pahoehoe lavaflows.

An outpouring of lava onto the land surface from a vent or fissure. Also, a solidified tongue like or sheet-like body formed by outpouring lava.

A lava flow is moving mass of molten lava on the Earth's surface. The solidified lava deposit from a molten lava flow is also called a lava flow.

Sheets or mounds of lava that flow onto the ground surface or sea floor in molten form and then solidify.

The flow of lava from a volcanic crater of fissure.

Magma that flows out at the Earth's surface.

In computer programming jargon, lava flow is a problem in which computer code written under sub-optimal conditions, is put into production and added to while still in a developmental state.
