What is the difference between a crater and a caldera?
A caldera is a large depression formed at the summit of a volcano, left behind by the excavation of magma. A crater is formed by an explosion or impact.
What are 5 things that come out of erupting volcanoes?
there are many parts of a volcano. There is the magma chamber: where all of the magma is held. There is the pipe: where the magma comes up and through the volcano. There is the dike, where where a slab forms when magma forces itself across rock layers. There is the crater, where a bowl shaped area forms around a volcanoes central vent. There is the vent: where magms comes out.
What do many small earthquakes near a volcano mean?
Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt. As such the small earthquakes are potentially a warning sign of an impending volcanic eruption.
When does magma become lava?
It should be magma is the hottest because it is usually molten rock that has not reached the surface during an eruption.Lava is 2nd hottest. It is the molten rock we see when a crack in the crust of the earth or a volcano eruption allows molten rock from beneath the crust to come up.
What is the Flow of magma through the earths surface called?
I believe the answer you may be looking for is either Lava or a Volcano
What is an opening that leads from the crater of a volcano down to pools of magma?
A volcanic vent or conduit is an opening that leads from the crater of a volcano down to pools of magma below the surface. This conduit allows magma to travel from the magma chamber to the surface during an eruption.
What is the funnel-shaped opening at the top of the volcano called?
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
What is a crater and a vent?
a crater is the opening at the top of a volcano. Vents are the openings that sometimes come at the sides of the volcano because there may be alot of magma in the volcano and it needs to come out somehow. so it sort of pressurizes the side of the volcano until it breaks through to make an opening. the opening is called a vent.
What connects pools of magma to crater?
A vent tube connects the magma chamber to the vent or crater of the volcano, hence allowing the magma to be released from the volcano and become lava.
What is it called that connects pool of magma to the crater?
Magma usually refers to molten rock when it is still underground, and a crater is a cup shaped depression in the surface whether in a volcano or not. If a crater were full of molten rock we'd call it lava. It might be fed by a magma pool below the surface.
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
Is a crater pipe the same as a vent?
No, a crater pipe and a vent are not the same. A crater pipe is a conduit that connects a magma chamber to the surface, allowing magma to erupt onto the surface. A vent is the opening at the surface through which volcanic material is erupted.
What is the difference between crater and magma chamber?
A crater can also be called a vent, and it is the funnel shaped opening at the top of a volcano which allows magma to escape as lava. The magma chamber is the hollow deep within the volcano which is supposedly linked to the core of the planet, bringing up molten rock from the middle of earth to be taken up the vent tube of the volcano to be released to the air.
What is the opening top of the volcano called?
The opening top of the volcano is called a crater. The super-heated gases and ash billows out of the mouth of hell before the magma erupts out destroying all in its path.
What is the crater of a volcano?
yes, I think so. because, very large volume of magma is ejected and then magma chamber can't support the volcano above it. then the volcano begins to sink into the earth.magma chamber empties and a new collapsed depression occurs.
Is a crater in a volcano a material or part in a volcano?
A crater is not a separate material or part of a volcano. It is a depression or hollow at the summit of a volcano that forms when the volcano erupts and releases magma, gases, and other materials. The crater is a result of the collapse or expulsion of material during the eruption.
The three main parts of a volcano are?
The three main parts of a volcano are the magma chamber where molten rock is stored beneath the surface, the vent where lava erupts to the surface, and the crater which is the bowl-shaped depression at the top of the volcano.
