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.
Which lava is less viscous rhyolitic or basaltic?
Basaltic lava is less viscous.
Is lava butte basaltic or granitic lava flow?
A lava butte is generally basaltic lava. Granitic lava flows (called rhyolitic when they form at the surface) are rare and do not cover much ground.
What is the opposite of basaltic?
The opposite of basaltic is rhyolitic. Basaltic rocks are formed from lava that is low in silica content, while rhyolitic rocks are formed from lava that is high in silica content.
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 are three different types of lava?
Basaltic, andesitic and rhyolitic
What are 3 kinds of magma?
Basaltic lava, Andesitic lava, and Rhyolitic Lava :] (glad to help)
Does basalt or rhyolite flow faster?
Basaltic lava flows much faster than ryholitic lava.
What type of lava flows the slowest?
Viscous lava, such as andesitic or rhyolitic lava, flows the slowest due to its high silica content. This type of lava tends to be thicker and more resistant to flow compared to basaltic lava, which is more fluid and flows more quickly.
How is basaltic lava different from granitic lava?
Basaltic lava is far less viscous, has less silica, erupts at a higher temperature and is denser than granitic lava (properly called rhyolitic lava when it is on the surface). Basaltic lava is composed primarily of pyroxenes and calcium rich plagioclase with small amounts of olivine. Rhyolitic lava primarily contains alkali feldspars and quartz.
Why is rhyolitic lava more expolsive than basaltic lava?
Rhyolitic lava is extremely viscous. This means it can hold more gas under pressure. The magma travels upward slowly until the gas, which has been held in place, comes out of solution pretty much all at one, resulting in an explosion. The high viscosity also means that the magma can build over time only to be released suddenly. Basaltic lava, which does not resist flow as much, can be extruded more gradually.
How do rhyolitic magma or lava and basaltic lava differ?
rhyolitic mama is associated with explosive volcanism and is ejected (blown out of) a volcano rapidly. Basaltic lavas are released during effusive volcanism that is not explosive, such as hawaii where the lave "flows" into the ocean slowly. Basaltic lavas have a lower silica content as well.
