Lava
Magma gets pushed through a vent due to the build-up of pressure beneath the Earth's surface. As the magma rises, it creates fractures in the rocks above, eventually reaching the surface through the vent. This process is driven by the buoyancy of the magma and the force of gas expansion within it.
Volcano?
because it is being pushed up from under the ground under pressure.
it erupted when magma ( lava ) and gases pushed the top off the mountain
Lava (AKA magma) escapes a volcano through a vent.
Lava (AKA magma) escapes a volcano through a vent.
First, the magma breaks open rocks underneath the volcano. Then, it flows up through cracks of the volcano. After it is all the way to the top, the volcano erupts. Then the magma and lava flows outside the volcano.
This is likely a volcanic dome, formed when magma pushes up through the Earth's crust but doesn't erupt outward. The magma cools and solidifies underground, creating a rounded hill-like structure.
This describes a volcano.
Magma collects in a magma chamber.the magma moves upward through a pipe, a long tube in the ground that connects the magma chamber to earths surface. Molten rock and gas leave the volcano through an opening called a vent. A lava flow happens when an are covered by lava pours out of the vent. A crater is a bowl shaped area at the top of the volcano around the central vent where magma comes out. Magma is beneath the volcano. Lava is the name of magma after it leaves a volcano. YOUre WELCome
The tunnel that magma goes through to reach the top of a volcano is called a conduit. This conduit is often a vertical pipe-like structure that connects the magma chamber beneath the volcano to the surface.
It doesn't. The volcano is a result of the magma travelling from the earths core through geological faults and breaking through the crust of the Earth. The mountain shaped Volcano that you see is the remnants of solidified ash and magma (pumice) which has been ejected from the magma chamber. This cone builds up over the fissure which ejects the magma onto the surface.
