Answer:

A volcano is a vent from which the material from a magma chamber escapes. This may include lava, rock fragments, ash, and gases. Volcanic eruptions can come from many types of structures.

Explanation:

Fissure Volcanoes

A fissure volcano, also referred to as a plateau basalt, is not what most people would envision at the mention of the word volcano. There is no mountain or hill; it is simply a gap in the earth’s surface from which volcanic activity erupts.

Shield Volcanoes

Shield volcanoes are generally large, rounded mountainous volcanoes with large craters near the top of the mountain. These broad, sloping volcanoes erupt over and over again and build the mountain higher over centuries of long-distance eruptions.

Stratovolcanoes

A stratovolcano, or composite volcano, is among the most dangerous erupting volcanoes. A stratovolcano is characterized by its triangular shape. They tend to have very steep slopes and are symmetrical.

Cinder Cone

Cinder cones are generally small volcanoes that are characterized by their rounded shape and relatively small height – usually a maximum of 1,000 feet.

Caldera

A caldera is a symbol of a very violent past. This type of crater is the aftermath of an eruption of another volcano that is so violent that the entire lava chamber of the volcano collapses and forms a giant crater in the ground that can sometimes extend for miles.
