A cloud of pumice, hot ash, and gas is called a pyroclastic flow. It is a fast-moving mixture of volcanic debris that can travel down the slopes of a volcano at high speeds, posing a significant danger to anything in its path.
A swift-moving cloud of pumice and ash is commonly known as a volcanic ash plume, which forms during explosive volcanic eruptions. This cloud consists of tiny rock fragments, volcanic glass, and gas that are ejected into the atmosphere, often rising to significant heights. The rapid movement of the cloud is driven by the force of the eruption and prevailing winds, posing hazards to air travel, human health, and the environment. These clouds can spread over large distances, affecting air quality and climate.
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
A large cloud of gas and dust in space is called a nebula. These nebulae are often the birthplaces of stars and planets, with various types such as emission, reflection, and dark nebulae.
An interstellar cloud made of gas, dust, and plasma in a galaxy.
The visible cloud of dust and gas in space is called a nebula. Nebulas are often regions where new stars are forming, and they can vary in size, shape, and color.
No, pumice is a naturally occurring volcanic rock that forms when lava with high water and gas content is ejected from a volcano. Fly ash, on the other hand, is a byproduct of coal combustion in power plants.
The cloud of ash, gas, and rock fragments that is produced during a volcanic eruption is called a volcanic plume or eruption cloud.
The ash rises because it is in a cloud of hot gas. This cloud is then carried by the wind.
Scientific studies estimate that the ash and pomice cloud of the initial eruption was 15 to 30 kilometres high and that there were six eruptions. The cloud of the first eruption hit Pompeii and when it fell a surge of gas and rock fragments hit Herculaneum on the other side of the volcano
A superheated incandescent cloud of gas and ash that swiftly travel down the volcano like an avalanche (also known as "the glowing cloud"). Scientifically, they are called pyroclastic flows or pyroclastic density currents.

Volcanoes can erupt ash, gas, and pumice in addition to or instead of lava.
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
Things that can be erupted include volcanic ash, pumice, solid rock fragments, and gas.
The ground-hugging avalanche consisting of ash, pumice rocks, and volcanic gas is called a "pyroclastic flow." It is a fast-moving, high-temperature mixture of volcanic ash, rock fragments, and gas that flows rapidly down the sides of a volcano during an eruption. Pyroclastic flows can be extremely dangerous and destructive.
An ash and gas cloud is a plume of ash particles and various gases emitted during volcanic eruptions. The ash consists of pulverized rock and volcanic glass, while the gases include water vapor, carbon dioxide, sulfur dioxide, and other compounds. These clouds can travel long distances and pose hazards to aviation, climate, and human health.
The closest match to this is a pyroclastic flow, but it isn't exactly lava: it is a cloud of hot ash, rock, and gas.
