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.
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.
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.
Which types of eruptions produce pahoehoe lava?
Pahoehoe lava is typically produced during effusive, non-explosive eruptions that have low viscosity and high temperatures. These types of eruptions are commonly associated with shield volcanoes, where the lava flows smoothly and forms a ropey or wrinkled surface as it cools.
What are the differences between the pahoehoe and AA?
Aa is slower, cooler, and has less sillica than pahoehoe. Pahoehoe is faster and moves quickly, and phoehoe has more silica, and is also darker than Aa
What is called hot fast-moving lava is called?
mafic
WhAT Magma type most often forms at hot spots?
Pahoehoe lava
Hot fast moving lava?
Hot, fast-moving lava is typically associated with Hawaiian-style eruptions, which feature low viscosity lava that can flow rapidly down slopes. This type of lava is usually characterized by its high temperature and ability to travel great distances in a short amount of time, posing a significant hazard to surrounding areas. It's crucial for residents near active volcanoes to stay informed about lava flow risks and heed evacuation orders to ensure their safety.
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.
Where is a thick and sticky lava found?
Thick and sticky lava, known as pahoehoe lava, is typically found in Hawaii and other hot spot volcanic regions. Pahoehoe lava has a smooth, rope-like texture due to its high viscosity and low gas content, which causes it to flow slowly and form characteristic swirls and folds as it cools.
What types of debris comes out of volcanoes?
Volcanic materials are divided into two main groups: Pyroclastic materials and lava flow materials.
