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
