What are the three types of volcanoes and how are they formed?

Answer 1

An active volcanoe is erupting or has erupted recently. A dormant volcano has not erupted recently, but may erupt again in the future. It could be considered as "sleeping". An extinct volcano will never erupt again.

Answer 2

Shield Volcanoes,Shield Volcanoes are made mostly of fluid lava flows. Flow after flow pours from a central summit vent. It builds up and turns into what looks like a warriors shield. Some of the largest volcanoes in the world are shield volcanoes. Some have diameters of 3-4 Miles and are 1,500 to 2,000 feet high. The Hawaiian islands are composed of chains of shield volcanoes. Cinder Cone volcanoes, and Composite Volcanoes Some of the world's biggest mountains are Composite volcanoes. Some people call composite volcanoes stratovolcanoes. Some of the most beautiful mountains are composite volcanoes such as Mount Fuji, Mount Cotopaxi, Mount Shasta, Mount Hood, Mount Rainer and Mount St. Helens. Most composite volcanoes have a crater at the top with a central vent or a group of vents where lava comes out.Cinder cones are the simplest kind of volcanoes. Cinder cone volcanoes have a bowl shaped crater and barely ever rise over one thousand feet. When cinder cone volcanoes erupt lava blows furiously into the air and breaks up into small pieces called cinders. There are many cinder cone volcanoes in western North America.

Answer 3

Ash and Cinder cones: Built up on successive layer of ash and cinder.

Shield Cones: Made mainly from basic lava and as such they have a gently sloping mountain.

Composite cones: Built up on layer of ash , cinder and lava.

Answer 4

1. Shield volcano or lava cone volcane is formed from very dense fluid lava which flows very rapidly and goes far down the slope solidifying and forming a shape of a broad slightly doomed structure. Volcanoes that erupted quietly have this kind of cone. Example of a shield volcano is Mauna Loa in Hawaii.

2. Cinder Cone Volcano- is formed from ashes and other dust materials thrown upso high that they can spread farther down . They have step sides or slopes with narrow base. An example of a cinder cone is the Paricutin Volcano near Mexico City.

3. Composite cones or strato volcano is formed from alternating rows of ash and lava. They are formed when the volcano erupts sometimes violently and at other times quietly. Example of composite cones are the Mayon Volcano in Bicol and Mt. Fujiyama in Japan.

Answer 5

The three types of volcanoes are shield volcanoes, stratovolcanoes, and cinder cone volcanoes. Shield volcanoes are formed by non-explosive eruptions with low viscosity lava flowing in broad, flat sheets. Stratovolcanoes are formed by alternating layers of ash, lava, and rock fragments from explosive eruptions. Cinder cone volcanoes are formed by the accumulation of volcanic cinders, ash, and rock fragments around a central vent.

Answer 6

The tree different types of valcanoes are shield, composite and cinder.

Answer 7

active volcano- frequently erupts

dormant volcano- rarely erupts

extinct volcano- NEVER EVER erupts
