What are Fast moving clouds of hot gas and ash that move down the side of a volcano?
That large, Heavy cloud is composed of fast-moving currents of hot gas and rock, which travel away from the volcano at speeds generally as great as 700 km/h (450 mi/h). The gas can reach temperatures of about 1,000 degree celcius(1,830 degrees fahrenheit). The flows normally hug the ground and travel downhill. most commonly known as a Pyroclastic flow.
A Pyroclastic surge is a fluidized mass of turbulent gas and rock fragments which is ejected during some volcanic eruptions. It is similar to a pyroclastic flow but contains a much higher proportion of gas to rock, which makes it more turbulent and allows it to rise over ridges and hills rather than always travel downhill as pyroclastic flows do.

What are three ways volcanoes are destructive?
Volcanic eruptions can cause widespread destruction through lava flows, which can destroy anything in their path. Ash clouds can disrupt air travel and pose health hazards to people and animals. Pyroclastic flows, fast-moving clouds of hot gas, ash, and rock can devastate areas near the volcano.
Is Nevado Del Ruiz explosive or non explosive?
Nevado Del Ruiz is considered an explosive volcano due to its history of generating explosive eruptions. Its eruptions are known to produce pyroclastic flows, which are fast-moving mixtures of hot gases, rock fragments, and ash that can travel at high speeds down the volcano's slopes.
What is wetter lahars or pyroclastic flows?
Lahars are wet. They are mudflows that result from volcanic ash mixing with water. Pyroclastic flows are superheated clouds of ash and gas that move down the slopes of a volcano. They are too hot to be wet.
What best why you see horizontal stripes in photographs of Jupiter and Saturn?
Horizontal stripes on Jupiter and Saturn are caused by fast-moving jet streams in their atmospheres. These bands of clouds are created by the planet's rapid rotation and heat distribution mechanisms, leading to alternating belts of lighter and darker cloud formations.
Does Mount Etna create pyroclastic flow?
Yes, Mount Etna is capable of generating pyroclastic flows. This volcano, located in Italy, has had historical eruptions that produced intense pyroclastic flows, which are fast-moving mixtures of hot gas, ash, and rocks that can travel down the slopes of the volcano at high speeds, posing a significant hazard to nearby areas.
What is a fast moving wave of rock and ash that rushes down the side of a volcano?
Pyroclastic Flow
Why do explosive volcanoes have a pyroclastic flow?
When a volcano erupts explosively, it releases clouds of hot ash, gas, and pumice. In many cases these clouds, or portions of them, are too dense to rise and instead race down the slopes of the volcano.
What are three ways volcanoes are destructive?
Volcanic eruptions can cause widespread destruction through lava flows, which can destroy anything in their path. Ash clouds can disrupt air travel and pose health hazards to people and animals. Pyroclastic flows, fast-moving clouds of hot gas, ash, and rock can devastate areas near the volcano.
Why is it windy at night after a hot day?
the sun has just gone down and the clouds are moving in
Is Nevado Del Ruiz explosive or non explosive?
Nevado Del Ruiz is considered an explosive volcano due to its history of generating explosive eruptions. Its eruptions are known to produce pyroclastic flows, which are fast-moving mixtures of hot gases, rock fragments, and ash that can travel at high speeds down the volcano's slopes.
What is a pyroclastic flow and how fast can they move?
A pyroclastic flow is a fast-moving mixture of hot gases, ash, and volcanic rock fragments that move down the slopes of a volcano during an eruption. They can reach speeds of up to 700 km/h (430 mph) or more, making them extremely dangerous to anything in their path.
How can you tell that Mount Fuji is a composite volcano rather than a shield volcano?
The volcano is very wide it means that it has mafic magma. The composite volcanoes have mafic magma in them. When the volcano erupts the lava flows down really fast, but hardens really slowly causing the volcano to widen its width size.
What is wetter lahars or pyroclastic flows?
Lahars are wet. They are mudflows that result from volcanic ash mixing with water. Pyroclastic flows are superheated clouds of ash and gas that move down the slopes of a volcano. They are too hot to be wet.

Why don't clouds fall back down to the ground?
Clouds do not fall back down to the ground because they are made up of tiny water droplets or ice crystals that are lighter than the air around them. These droplets and crystals are constantly moving and being carried by air currents, which keeps the clouds suspended in the sky.
What is a cloud of pumice hot ash and gas called?
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.
Why doesn't a stream meander in mountains?
A stream flowing down a mountain is moving to fast to form meanders.
