Volcanoes primarily produce igneous rocks when magma erupts and cools. If the magma cools and solidifies beneath the Earth's surface, it forms intrusive igneous rocks, such as granite. If the magma erupts onto the surface as lava and cools quickly, it forms extrusive igneous rocks, such as basalt. The specific type of rock depends on the composition of the magma and the cooling conditions.
What else can I help you with?
What type of rock makes shield volcanoes?
Shield volcanoes are typically formed from basaltic lava flows, which are low in silica content and very fluid. This type of lava allows for the gradual buildup of wide, gently sloping volcanic cones characteristic of shield volcanoes.
What kind of rock is found in a shield volcano?
Shield volcanoes are primarily composed of basaltic rock, which is a type of volcanic rock that is low in silica content and high in iron and magnesium. This type of rock creates gently sloping shield volcanoes due to its low viscosity and ability to flow easily during eruptions.
Which type of rock is associated with volcanoes?
Igneous rocks are found in areas of volcanism
What type of volcanic rock do you find in a explosive volcano?
Explosive volcanoes can produce pumice and tuff.
How were the Hawaiian islands formed and which type of rock is probably most common in Hawaii?
they were formed by underwater volcanoes
What type of rock is formed from volcanoes magma or lava?
igneos rock
What type of mountain forms from molten rock?
Volcanoes
What is a type of rock that bursts out of a volcanoe that starts with the letter b?
Basalt is a rock formed by volcanoes.
What rock is made in earthquakes and volcanoes?
igneous rock. It is made from hardened magma. That's from volcanoes. I don't think earthquakes make rocks.
What type of rock does a volcano form?
volcanoes create igneous rocks

What type of rock forms in volcanoes along the continental margins?
igneous rocks
Which type of rock is associated with volcanoes?
Igneous rocks are found in areas of volcanism
What part do volcanooes play in the rock cycle?
Volcanoes melt the rock and eventually erupt. Once it erupted the rock starts to setal and cool into a certain type of rock
What type of volcanic rock do you find in a explosive volcano?
Explosive volcanoes can produce pumice and tuff.
Do all volcanoes have molten rock?
All volcanoes have molten rock. o.0
