A stratovolcano is a name given to a volcano that has grown by progressive stacking of eruptive products (e.g. lava flows and pyroclastic flows). The term composite volcano is often preferred as it does not suggest that this stacking occurs in neat layers (i.e. 'strata' is a geological term for a layer of rock).
Andesite is a type of igneous rock which is characterized by an intermediate amount of silica. It has more silica than basalts (e.g. Hawaii) and less silica than dacites (e.g. Mt. St. Helens).which it means active
What else can I help you with?
Which type of lava does mount Eyjafjallajokull have?
probably basaltic lava because the 2010 eruption was very explosive
What type of lava does Eyjafjallajökull Volcano produce?
Eyjafjallajökull Volcano produces basaltic and andesitic lava. The eruption in 2010 resulted in the release of both types of lava, creating a mix of volcanic products.
What is the relationship between the viscosity of andesitic lava and its flow behavior during volcanic eruptions?
The viscosity of andesitic lava affects its flow behavior during volcanic eruptions. Higher viscosity lava flows more slowly and tends to form thicker, blockier lava flows, while lower viscosity lava flows more easily and can travel further before solidifying. This relationship influences the type and intensity of volcanic eruptions.
Is pumice andesitic?
Yes, pumice is typically an andesitic volcanic rock. It forms when frothy lava containing high amounts of gas vesicles cools rapidly and solidifies. This type of volcanic rock is commonly found in areas with explosive volcanic activity.
What type of lava does Eyjafjallajokull produce?
Eyjafjallajokull volcano in Iceland produces andesitic lava, which is a type of intermediate lava that is typically more viscous than basaltic lava. This can lead to explosive eruptions as gases get trapped within the molten rock before being released.
Is basaltic lava less fluid than andesitic lava?
No, basaltic lava is typically more fluid than andesitic lava due to its lower silica content. This results in basaltic lava flowing more easily and spreading over larger areas compared to andesitic lava.
What are 3 kinds of magma?
Basaltic lava, Andesitic lava, and Rhyolitic Lava :] (glad to help)
What type of lava flows from llaima?
basaltic-andesitic
Which type of lava does mount Eyjafjallajokull have?
probably basaltic lava because the 2010 eruption was very explosive
How extrusive rocks form?
extrusive rocks can form from Basaltic Lava and Andesitic Lava. :)
What type of lava does santa maria have when it flows?
Santa Maria volcano in Guatemala typically produces andesitic lava when it flows. Andesitic lava is characterized by its intermediate viscosity and silica content, resulting in a mixture of smooth and blocky textures.
What type of lava does mount usu have?
Mount Usu in Japan typically erupts with andesitic lava, which is a type of intermediate lava with a higher silica content compared to basaltic lava. Andesitic lava flows tend to be slower-moving and more viscous than basaltic lava.
What are three different types of lava?
Basaltic, andesitic and rhyolitic
What type of lava forms mt hood?
Mt. Hood is primarily composed of andesitic lava, which is intermediate in composition between basaltic and rhyolitic lavas. Andesitic lava is characterized by its viscosity and tendency to form lava domes, lava flows, and pyroclastic flows.
What type of lava comes out of El Chichon?
El Chichon volcano in Mexico typically erupts with andesitic lava, which is known for its intermediate viscosity between basaltic and rhyolitic lava types. Andesitic lava flows can be thick and slow-moving, leading to significant volcanic hazards.
What are some examples of lava?
Examples of lava include basaltic lava, andesitic lava, and rhyolitic lava. Basaltic lava is fluid and forms flat landscapes like the Hawaiian Islands, while andesitic lava is stickier and can create steep volcanoes like those in the Andes. Rhyolitic lava is very viscous and can lead to explosive eruptions, forming features like Yellowstone's geysers.
What type of lava does thera volcano have?
The Thera volcano, also known as Santorini, has both basaltic and andesitic lava. Basaltic lava is more fluid and flows easily, while andesitic lava is thicker and can lead to explosive eruptions. Thera's volcanic activity has produced different types of lava throughout its history.
