The purpose of this project is to explain and classify the structure of volcanoes.
The word volcano originally comes from the name of the Roman god of fire, Vulcan.
Most people think of volcanoes as large shaped mountains. But there are other kinds of volcanos - Wide Plateaus, fissure vents, and Bulging dome shapes. Common volcanic gases include -water vapor carbon dioxide sulfur dioxide Hydrogen fluoride Hydrogen chloride Hydrogen sulfide.
Liquid rock is called magma when it is under the earth’s surface and after it comes out it is called lava.
Seventy-five percent of the volcanoes on the Earth. Are found in an area in the Pacific Ocean. This is known as the Ring of Fire. The largest know volcano is in our solar system. The known largest volcano is located on Mars. The largest volcanoes is called Olympus Mons. It’s mouth is six hundred kms wide with an elevation of twenty-one kms.Pumice is a unique volcanic rock (igneous) that can float in water.It can also be used as abrasive and is sometimes used in beauty salons for removing dry skin.
Volcanoes are openings in the Earth’s surface. When they are active they can let ash, gas and hot magma escape in sometimes violent and spectacular eruptions. Volcanoes are usually located where tectonic plates meet. Large volcanic eruptions can reflect radiation from the Sun and drop average temperatures on Earth by around half a degree. There have been several examples of this over the last century. There are also volcanoes found on the ocean floor and even under icecaps, such as those found in Iceland.
Understanding information about volcanoes is important because while volcanic eruption is dangerous, it can be effective too in that in some countries such as in Iceland, the heat energy from magma is used for running power plants. This type of energy is known as geothermal energy.
