Fast moving hot lava that has low viscosity is called?
Fast moving hot lava with low viscosity is called "pahoehoe." It has a smooth, ropy texture due to its high temperature and low resistance to flow.
What is the difference between tephra and pyroclastic flow?
Tephra refers to fragmented volcanic material ejected during an eruption, including ash, lapilli, and bombs. Pyroclastic flow is a fast-moving mixture of hot gas and volcanic particles that flows down the side of a volcano during an explosive eruption, capable of reaching speeds of hundreds of kilometers per hour and causing widespread destruction.
Is lava rock hot to the touch?
Yes, lava rock is hot to the touch because it retains heat from its formation through volcanic activity.
Hot liquid rock on the earth's surface is called?
The is called "lava", before it comes out on the surface it is called "magma".
Which type of rock is formed when hot lava cools?
Hot lava, when cooled and solidified, forms igneous rocks. Examples include basalt, granite, and obsidian.
What is called hot fast-moving lava is called?
mafic
Fast moving hot lava that has low viscosity is called?
Fast moving hot lava with low viscosity is called "pahoehoe." It has a smooth, ropy texture due to its high temperature and low resistance to flow.
What is the slow moving and hot moving lava called in Hawaiian?
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
Is block lava the same as pyroclastic flow?
No. Block lava is low-moving viscous lava, usually of andesitic or similar composition. A pyroclastic flow is a very fast-moving mixture of hot ash, rock and gas.
Is pahoehoe fast moving hot lava?
No. Pahoehoe is lava that forms a smooth, ropey surface. It may flow relatively quickly at times, but often flows very slowly.
What are the differences between pahoehoe and Aa what kind of eruption produces these types of lava-?
Pahoehoe is hot, fast-moving lava that has a low viscosity. AA lava has a cooler temperature and moves more slowly. Quiet eruptions are the type that produce these two types of lava.
When you are measuring temperature you are measuring the?
How fast molecules are moving. If they are moving fast its hot, but if they are moving slow it is cold
What ate the differences between pahoehoe and Aa what kind of eruption produces these types of lava?
Pahoehoe and AA lava are produced by quiet eruptions. This means that instead of a blast or explosion, the lava just flows out of the volcano. Pahoehoe lava is hot and flows quickly. AA lava is cooler in temperature and doesn't flow as quickly.
What kind of eruption is hot lava?
Hot lava comes from effusive eruptions, where magma is relatively low in silica and flows easily out of the volcano. This type of eruption typically results in slow-moving lava flows that can cover large areas.
When mount merapi erupts do they try and stop the lava flow?
No. Recent eruptions of Mount Merapi have produced pyroclastic flows instead of lava flows. Pyrolastic flows are fast-moving currents of hot ash, rock, and gas. There is no way of stopping or deflecting them.
What can you see when volcanoes erupt?
During a volcanic eruption, you can see ash, lava, and gases being expelled from the volcano's vent. Sometimes there are also pyroclastic flows, which are fast-moving currents of hot gas and rock. The eruption may also produce volcanic lightning, ash clouds, and lava fountains.
How fast can lava flows travel on steep slopes?
Lava is slow only, 10 mph at fastest but hot ash can go 200 mph.
