Lava flow.
Hot magma outside a volcano is called lava. Lava is molten rock that flows out of a volcano during an eruption.
A river of lava is called a lava flow. It is a mass of flowing molten rock that moves downhill from a volcano during an eruption.
If it reaches the surface, it is magma or lava. If it merely intrudes into rocks already formed, it is intrusive. Such as sills and dikes.
when the hot lava cools deep inside the earth, it is called intrusive igneous rocks. when the hot lava cools on the surface of the earth, it is called extrusive igneous rocks.

lava
Hot lava comes from effusive eruptions, where magma is relatively low in silica and flows easily out of the volcano. This type of eruption typically results in slow-moving lava flows that can cover large areas.
