Volcanoes erupt and shoot up lava due to the buildup of pressure from molten rock, or magma, beneath the Earth's surface. As magma rises, gases dissolved in it expand, creating pressure that forces the magma upward through cracks in the Earth's crust. When the pressure exceeds the strength of the surrounding rock, it results in an explosive eruption or a more effusive flow of lava, depending on the magma's composition and viscosity. This process is driven by geological activity and the movement of tectonic plates.

What are 3 types of volcanic mountains and explain?
Shield volcanoes are made from runny lava and steep sides. Cinder cone volcanoes are made from lava layers that alternate with layers of cinder. composite volcanoes shoot lav into the air.
Can geysers shoot up lava?
No, geysers eject hot water and steam. Volcanoes eject lava. If enough water gets into a volcano, the water turns to steam and the volcano becomes an exploding volcano, not a geyser.
What are the different types of volcanoe?
Volcanoes are grouped into four types: cinder cones, composite volcanoes, shield volcanoes and lava volcanoes. They are: Cinder Cones: They are circular or oval cones made up of small fragments of lava from a single vent. They have been blown into the air, cooled, and fallen around the vent. Composite: They are steel-sides and composed of many layers of volcanic rocks. Mt. Rainier and Mount St. Helens are examples of this type of volcano. Shield: Shaped like a bowl or shield in the middle, they have long gentle slopes made of basaltic lava flows. The volcanoes that formed the basalt of the Columbia Plateau were shield volcanoes. Lava Volcanoes: Deep sided mound formed by lava that is too thick to flow. The lava piles up near the vent.
The magma released from volcanoes is?
lava
What are types of valcano?
The main types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), cinder cone volcanoes, and lava domes. Shield volcanoes have gentle slopes and are formed by fluid lava flows. Stratovolcanoes are tall, steep-sided cones composed of layers of lava and ash. Cinder cone volcanoes are small, steep-sided cones made of pyroclastic material. Lava domes are mounds of thick, slow-flowing lava piling up near a volcano's vent.
How high does the sierra volcanoes lava shoot up?
it can shoot up to 1,000 to 2,000 above the volcano
Do all volcanoes shot out the same lava?
No, not all volcanoes shoot out the same lava. There are four different kinds of lava. 1.) Volcanic 2.) magma 3.) sedimentary 4.) diesel hope this helps!

No, geysers eject hot water and steam. Volcanoes eject lava. If enough water gets into a volcano, the water turns to steam and the volcano becomes an exploding volcano, not a geyser.
Do volcanoes need lava to be known as actual volcanoes?
No, volcanoes do not need lava to be volcanoes.
Can lava make volcanoes?
NO, volcanoes make lava.

Lava Volcanoes: Deep sided mound formed by lava that is too thick to flow. The lava piles up near the vent.
Do shield volcanoes have a steep sloping cone made up of rocks and lava?
No. Shield volcanoes have gentle slopes composed almost entirely of cooled lava flows.
How high can lava shoot up in the air?
is u mad at me
Are geysers volcanoes?
No, geysers send up fountain like jets of water and steam. Volcanoes erupt lava.
How do volcanoes aruped?
the magma pushes up and becomes lava. when there is enough pressure lava spews out. that is how a volcano erupt
What are some interesting fatcs about volcanoes?
The interesting facts about volcanoes are that they blow up and lava and coal come out of them and it is very dangerous if you get hit by lava or coal because it is really hot.
