Are there three types of lava or four?
It depends on what criteria you use. If you go with the kind of flow there are four.Pahoehoe (ropey lava flows)A'a (jagged, more viscous flows)Pillow lava (rounded lumps that form underwater)Block lava (very viscous, very slow moving)The first three are all associated with mafic lava, also called basaltic lava, which refers to a specific composition. Pillow lava is sometimes ignored as are black lava flows, which don't much resemble traditional images of lava.In terms of composition there are also 4 basic types on a spectrum of increasing silica content and viscosityMafic (basaltic)Intermediate (andesitic)Intermediate-felsic (dacitic)Felsic (rhyolitic)These can be further subdivided. Another, rare kind of lava exists called carbonatite. This strange lava is composed of carbobnates rather than silicates as the others are, and is only found in one volcano: Ol Doinyo Lengai in Tanzania.
Where do most rocks have basaltic composition?
Most rocks with basaltic composition are found in volcanic regions, such as volcanic islands and mid-oceanic ridges. They are also commonly found in continental flood basalt provinces, which are large expanses of basaltic lava flows that cover extensive areas of land. Basaltic rocks can sometimes be found in other settings as well, such as in certain types of metamorphic rocks.
The three types of volcanoes?
Shield volcanoes are the largest of the three types of volcanoes, built from basaltic lava flows and shaped like a gentle dome. Cinder cone volcanoes have very steep slopes and reach heights of 300 meters or less, and are made from ejected lava. Composite Cone Volcanoes are large symmetrical cones made from viscous lavas that are extruded, and they are the most violent volcanoes of the three.
How did AA lava get its name?
Aa lava is a basaltic lava with a flow characterized by rough surfaces of clinker.
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
How does the types of material that erupt from a volcanoes determine the shape of the volcanoes?
Fluid basaltic lava flows that erupted nonexplosively spread like hot syrup poured onto a plate. Ash flows are from huge MORE

What types of volcano rock fragments or lava come out of kilauea volcano?
Kilauea generally produces lava flows and lava fountains. Its current activity has also involved the formation of lava lakes. All of the lava involved is basaltic.

What types of volcanic rocks are generally found at divergent plate boundaries?
Basaltic
What are types of rocks and minerals found in the island of Hawaii?
Mostly basaltic lavas.
What are the three main types of magma what factor determines these classifications?
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.
What is the type of magma contain a lot of silica and water vapor is?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
