What else can I help you with?
Which lava is less viscous rhyolitic or basaltic?
Basaltic lava is less viscous.
What are the three types of lava flows associated with basaltic lava?
basaltic lava can form a'a, pahoehoe, or pillow lava.
Does basaltic or rhyolitic lava flow faster?
Basaltic lava flows much faster than ryholitic lava.
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 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 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.
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 type of lava do cinder cones have?
Basaltic. There is more gas content than in most basaltic magma so that when a cinder cone erupts, The pressure builds up and makes the eruption somewhat explosive. Tephra, or dried lava/magma, is shot up, and joined to the volcano making it larger.
What type of lava does shield a shield volcano have?
Mafic, more commonly called Basaltic.
What type of lava comes out of shield volcano?
Basaltic lava.
Does basilic lava have low silica?
Yes, basaltic lava has low silica content compared to other types of lava. Basaltic lava is typically rich in iron, magnesium, and calcium, which contribute to its low silica content. This low silica content also makes basaltic lava less viscous and more likely to flow easily.
What lava type is pumice?
basaltic
