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.
The volcanoes of Hawaii form fron thin basaltic magma that tends to erupt quietly What is one reason for the quiet eruptions?
Basaltic magma allows dissolved gases to bubble upward and escape
What type of volcano has lava that primarily consists of basalt?
Both shield volcanoes and cinder cones primarily erupt basaltic lava.
What is the source of materials for volcanoes that erupt in both ways how do you know?
Crusts must have both granitic (continental) plate and basaltic (oceanic) plate to cause both explosive (granitic magma) and non-explosive (basaltic magma) eruptions
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.

Can a stratovolcano erupt blocky lava?
Yes. Stratovolcanoes can erupt blocky lava flows, basaltic lava flows, or may erupt explosively.
What lava is in fissure volcanoes?
Fissures usually erupt basaltic lava.

Basaltic magma allows dissolved gases to bubble upward and escape
Will rhyolitic magmas erupt at lower temperatures than basaltic magmas?
Yes, rhyolitic magmas are several hundred °C colder than basaltic magmas. This is because the melting point of a rhyolitic magma is much lower than that of basaltic magma. Instead of heating up rhyolitic magma much above its melting point it will ascend and either crystallize in the Earth's interior as a pluton or erupt.
Does molten material erupt inside the central valley of mid-ocean ridges?
yes

How are shield volcanoes and cinder cone volcanoes somewhat same?
Both erupt basaltic lava, which has a low silica content and a high temperature.
Does AAA lava erupt quietly?
Generally yes. A'a and pahoehoe are both varieties of basaltic lava, which usually erupts fairly quietly.
Why do some volcanoes erupt while others erupt quietly?
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
Were can volcanoes erupt?
Along plate boundries.
