Caldera-forming eruptions do not involce lava flows but massive plumes of ash and pumice. The material produced is usually rhyolite. After a caldera-forming eruption, however, the composition can shift, especially since eruptions can be triggered by the mixing of different types of magma.
What else can I help you with?
Is mount Krakatoa a shield volcano?
No. Caldera and shield volcanoes are quite different. Shield volcanoes usually undergo effusive eruptions, the least violent type and produce basaltic lava. Caldera forming volcanoes erupt explosively and are the most violent. They generally produce rhyolitic lava.
What kind of lava do Composite volcanoes produce?
it has mafic and felsic duhhhhh
What large landform is usually made up of a vent magma chamber and lava?
A volcano is a large landform that is usually made up of a vent leading to a magma chamber below the surface, from which lava erupts. Volcanoes can vary in shape and size, depending on the type of eruption and the composition of the lava.
Do volcanoes produce large amounts of ash when they erupt?
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
How much lava can a volcano produce?
Depends, all volcanoes have different amounts of lava.

What kinds of lava do volcanoes with lower viscosity magma produce?
They produce basaltic lava.
Do volcanoes produce large amounts of ash when they erupt?
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
Do all volcanoes produce lava rivers?
No.
Does granitic lava come out of a cinder cone volcano?
No. Cinder cones erupr basaltic and occasionally andesitic lava. "Granitic" lava, called rhyolitic when it is erupted, erupts primarily from composite volcanoes (also called stratovolcanoes), and some caldera volcanoes.
Is lava a kind of fossil?
Lava is the liquid rock that comes out of volcanoes.
Name three things that can come out of volcanoes?
Volcanoes can produce lava, ash, and gas.
How much lava can a volcano produce?
Depends, all volcanoes have different amounts of lava.
What are the 4 types of volcanoes which exist and what type of lava do they produce?
shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.
How much lava comes out of a volcanoes?
The amount of lava that comes out of a volcano can vary greatly depending on the eruption type and size of the volcano. In general, volcanoes can produce anywhere from a few cubic meters to millions of cubic meters of lava during an eruption. Some eruptions, such as those from shield volcanoes, can produce lava flows that extend for tens of kilometers.
