vent
why is the creater and the magma and the ventard the most important part of a volcano?
The Volcano has a huge structure below it. The molten rock deep within it is called Magma. A subsidiary volcano may form from the main body, this is called a Parasitic cone. Some times some volcanic materials may seep out near the volcano, this opening is called Vent. The molten rock erupting from the Volcano is called Lava. The mouth of the volcano is called Crater. The highest point of a volcanic mountain is called Summit while the underground passage of magma is called Conduit. The Channel through which lava is ejected out is called the Throat. Ash or fragments of rocks and lava are what is blasted out forming Ash clouds due to the explosion
Being a less dense liquid, it rises toward the surface, seeking the path of least resistance. The volcano is simply a structure created by the rising magma and the surface features of its lava.
Lava collects inside a Magma Chamber. "When an erupting volcano empties a shallow-level magma chamber, the edifice of the volcano may collapse into the voided reservoir, thus forming a steep, bowl-shaped depression called a caldera" (Quoted from How Volcanoes Work at http:/wwwzperiodzgeologyzperiodzsdsuzperiodzedu/how_volcanoes_work/Calderaszperiodzhtml)

This is known as a volcanic vent.

it is part of a volcano

Do you mean the hole it comes out of the ground through? That is a volcano. More likely, you mean the hole made when the lava starts to cool and the liquid part inside can suddenly run out. That is a lava tube.
Some volcanoes form from mountains that are hollowed out over a certain period of time when the tectonic plates have allowed a little magma to slip between them. (I will tell you the parts of the volcano in a sec) Other volcanoes are formed from under sea volcanoes that have erupted and the lava cooled and settled on until it reached above sea level (that is how Hawaii formed). PARTS OF THE VOLCANO: magma- hot liquid stored inside of the earth lava- magma that reaches earth's surface magma chamber- the place where the magma is stored until it can go up the pipe (sometimes this can fuel more then one volcano) pipe- the hollowed out tube inside the volcano that the magma flows up to reach the vent (this part can have side tubes that go a little ways into the side of the volcano) vent- the place on the volcano that the magma first bursts out of c??- a large bowl shaped part of the volcano that the lava blows out and then runs down the side of the volcano :D Sorry i don't know of any pictures that show this process except for in my science book!
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.
