Rhyolitic magma has a high viscosity content, making it flow slowly. Because of its slow moving liquid rock, it doesn't flow very far from the main vent, producing a very tall composite volcano. Once lava is released from the main vent it flows down the sides of the volcano and hardens. Because it is slow moving, some times it doesn't get all the way to the ground before it hardens, that's why composite volcano's are vary tall. Rhyolitic magma is also high in gas and silica content, making it very explosive.

What type of lava comes from what volcano?

Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.


What is the type of lava in the composite volcanoes?

Composite volcanoes typically erupt with a mixture of lava types, including both viscous lava (andesitic or rhyolitic) that can lead to explosive eruptions, as well as more fluid lava (basaltic) that can flow long distances. This combination of lava types is what gives composite volcanoes their steep-sided profile.


What kind of lava do caldera volcanoes produce?

Caldera-forming eruptions do not involce lava flows but massive plumes of ash and pumice. The material produced is usually rhyolite. After a caldera-forming eruption, however, the composition can shift, especially since eruptions can be triggered by the mixing of different types of magma.


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 kind of lava do Composite Volcanoes have?

Composite volcanoes, also known as stratovolcanoes, typically have more viscous lava compared to shield volcanoes. This lava is comprised of a mixture of gas-rich, acidic magma and silica, which makes it thicker and more prone to explosive eruptions.

What kind of lava does a lava volcano have?

The textbook answer would be granitic or rhyolitic lava. In reality composite volcanoes are highly variable, erupting the full range from basaltic to rhyolitic (granitic) materal and everything in between includin andesite and dacite. One composite volcano in Africa erupts unique carbonatite lava.

Does granitic lava come out of a cinder cone volcano?

No. Cinder cones erupr basaltic and occasionally andesitic lava. "Granitic" lava, called rhyolitic when it is erupted, erupts primarily from composite volcanoes (also called stratovolcanoes), and some caldera volcanoes.

What kind of magma does Yellowstone have?

The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.


Which type of lava-basaltic lava or rhyolitic lava flows faster and why?

Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.


Is lava a kind of fossil?

Lava is the liquid rock that comes out of volcanoes.


What type of lava does Yellowstone caldera have?

Both rhyolitic and basaltic lava flows have been found in the Yellowstone Caldera. There are alro large deposits of rhyolitic tuff.


What kind of lava do lava dome volcanoes contain?

Lava domes usually consist of rhyolite or dacite lava.
