A volcano or volcanic vent is an opening in the earth's surface that allows melted rock (lava) to flow out.
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.
The asthenosphere can flow like a plastic because it is composed of partially melted rock that has a high temperature and pressure. This partial melting allows the rock to deform and flow slowly over long periods of time, similar to how plastic can be molded and shaped under the right conditions.
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.
Water is not a major component of melted rock. The heat has turned any water into steam.

Pumice is a solid material; it is not melted although it used to be melted rock when it was originally formed by a volcano.
partly melted rock material
A volcano or volcanic vent is an opening in the earth's surface that allows melted rock (lava) to flow out.
When rock is melted into liquid form, it is called magma. Magma is generated beneath the Earth's surface and can eventually cool and solidify to form igneous rocks.

The asthenosphere consists of partially-melted, ductile rock that is composed mainly of silicate minerals such as olivine and pyroxene. It also contains small amounts of water and other volatiles which contribute to its plasticity and ability to flow.
The asthenosphere is not a type of rock, but rather a layer in the Earth's mantle. It consists of partially melted rock that behaves as a plastic-like material, allowing tectonic plates to move on top of it.
no, if it is melted, it is igneous
magma is less dense than the surrounding rock, so it is forced upward to the earth's surface
