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.
What else can I help you with?
What are 3 kinds of magma?
Basaltic lava, Andesitic lava, and Rhyolitic Lava :] (glad to help)
What kind of magma does Yellowstone have?
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
Correct order of decreasing magma viscosity?
The amount of viscosity present in magma depends on the amount of silica it has. A composite volcano produces rhyolitic lava which is very thick. A shield volcano produces a basaltic lava with less silica and significantly less viscosity.
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.
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.
Which lava is less viscous rhyolitic or basaltic?
Basaltic lava is less viscous.
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.
Does basaltic or rhyolitic lava flow faster?
Basaltic lava flows much faster than ryholitic 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 magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
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.
