When melted rock reaches Earth's surface, it is called lava. Lava can flow out of volcanoes during an eruption, cooling and solidifying to form igneous rock.
A volcano or volcanic vent is an opening in the earth's surface that allows melted rock (lava) to flow out.
Large cracks in a lava flow where melted rock can ooze out are known as fissures. Fissures can result from the pressure buildup of magma beneath the surface, causing it to find weak points in the Earth's crust to escape from. These openings can lead to the formation of lava flows and volcanic eruptions.
The lava is melted rock called magma when it is underground, then it is exposed and is then called lava. The volcano erupts, and it hardens into igneous rock. If the igneous rock heats up again, it is lava once more!
Melted rock that flows out of the Earth's surface is called lava. Lava is molten rock that erupts from a volcano or fissure and is typically hot enough to flow downhill before cooling and solidifying.
Partially melted snow is........ partially melted snow!
The melted rock coming from a volcano is called lava.
Lava.
Melted rock is that hasn't surfaced is "Magma".If the melted rock already has surfaced, it is called "Lava".
Lava
Magma(or lava if it is already above or out of the volcano
