Before a volcano erupts, energy builds up primarily through the accumulation of magma in the magma chamber beneath the Earth's surface. As magma rises, it contains dissolved gases that increase pressure within the chamber. When the pressure exceeds the strength of the surrounding rock, it can cause fractures and pathways to form, allowing the magma to ascend further. Eventually, this pressure release leads to an explosive eruption or a more effusive flow of lava.

Which is more likely to be dangerous a volcano that erupts frequently or a volcano that has been inactive for 100 years why?
A volcano that erupts frequently keeps pressures down on the inside of the volcano. People in the area become familiar with the signs it is about to erupt. But a volcano that has sat dormant will fool people into thinking the mountain is safe, even 'dead'. New generations never experienced the volcano erupting. They may have built houses and businesses too close to the mountain. When it erupts, the volcano will have up to 100 years of pressures built up behind the eruption. It might not give any warning signs before it erupts. So not only will people be caught off guard, living too close, the eruption may be so large that people cannot get away fast enough.
Which is more likely to be dangerous a volcano that erupts frequently or a volcano that has been active for 100 years why?
A volcano that erupts frequently is more likely to be dangerous because it can cause more frequent destruction and pose a continuous threat to nearby areas. However, a volcano that has been active for 100 years could potentially have built up pressure and be primed for a larger, more explosive eruption. Both types of volcanoes can be hazardous in different ways.
How do volcanos get energy?
Volcanoes get their energy from the Earth's interior, where molten rock (magma) rises towards the surface due to the heat and pressure generated by processes like mantle convection and tectonic plate movement. When this magma erupts onto the surface, it forms a volcano.
If a volcano erupts is that volcano dead?
No. You see or hear on some shows,"oh, this volcano hasn't erupted since 1907." or something. But then it erupts. Yes, that can happen. A period of a few hundred years isn't very long for a volcano, especially ones that erupt violently. The mountain of a volcano is built up by a series of eruptions over the course of thousands if not millions of years. After erupting a volcano may go dormant for a few years or event a few centuries, but it is not dead and in nearly all cases activity will eventually resume. As once example, the volcano at Yellowstone has not had a magmatic eruption in 70,000 years, but it is still monitored for activity as magma is present beneath it.
What is a mountain built from magma?
A mountain built from magma is called a volcanic mountain. It forms when magma from beneath the Earth's surface erupts through a vent or fissure, cools, and solidifies to create layers of volcanic rock and ash over time. Examples include Mount St. Helens in the United States and Mount Fuji in Japan.

What is a lava barrier?
A lava barrier is where something is built on high rock so that when a volcano erupts and the lava flows down, it flows down the barrier around it.

Where did shield volcanoes usually come from?
A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. Shield volcanos usually come from highly fluid lava that erupts, which travels farther than lava erupted from stratovolcanos.
How does a volcano erupts pictures?
Volcanoes erupt when molten rock, ash, and gases are expelled from a vent in the Earth's surface due to built-up pressure underneath. The eruption can be explosive, sending debris high into the air, or effusive, with lava flowing steadily out of the volcano. The process can be visually captured through photographs or videos showing the eruption column, lava flows, and ash clouds.
What built the volcano mauna loa?
Mauna Loa was built by repeated eruptions of lava over hundreds of thousands of years. As the Pacific tectonic plate moves over a hotspot in the Earth's mantle, magma erupts through the crust to form the volcano. The lava builds up layer by layer, eventually creating Mauna Loa, one of the largest volcanoes in the world.
What is a volcano built out of nonexplousive eruptions called?
A shield volcano.
Is there a town built on a volcano in Britain?
Edinburgh castle is built on the site of an extinct volcano.
How volcano is build and what are the materials?
A volcano is built through the accumulation of materials such as lava, ash, and rock fragments that are ejected during volcanic eruptions. The core of a volcano is made up of solidified magma, while the surrounding layers are built up over time as the volcano erupts and new materials are added. These materials include basaltic lava, pyroclastic rocks, and ash.
