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.

How fast does a volcano erupt?
Volcanoes do erupt fast at 50 mph, And Volcanoes could melt people down.
What is it called when a fast moving stream slows down and deposits sediment?
It is called deposition. It occurs as friction or gravity overcomes the force of the moving water.
Why does rain look like it isn't moving from far away?
There is som much coming down at a time and it is moving fast so it looks like on big cloud.
What happens during volcano eruptions?
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 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.
Why is it windy at night after a hot day?
the sun has just gone down and the clouds are moving in

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.
How does the clouds pour rains?
We say that "it is pouring" when there is the type of rain that has big drops and is coming down fast and for a period of time. The usual process of raining is taking place and there are not any puddles up in the clouds.
What is it called when a fast moving stream slows down and deposits sediment?
It is called deposition. It occurs as friction or gravity overcomes the force of the moving water.
Why doesn't a stream meander in mountains?
A stream flowing down a mountain is moving to fast to form meanders.
What damage did the clouds of ash do when the Eyjafjallajökull Volcano do this spring when it erupt?
The smoke when up in the air obviously and planes to Europe and to America were shut down. Many people were stuck in Europe or America
How can you use integers to represent the velocity and the speed of an object?
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
When a wrecking ball hits a wall it is not moving fast How can it have enough momentum to knock down a wall?
Momentum is a function of both mass and speed. The wrecking ball isn't moving very fast, but it is extremely heavy; that is where its momentum comes from.
Why does rain look like it isn't moving from far away?
There is som much coming down at a time and it is moving fast so it looks like on big cloud.
