How does it affect volcanoes on Earth's surface.? Types of volcanoes

The volcano, a nozzle present on the surface of the earth, and contain fireballs, and graduated magma, which are called (lava), and scientifically dubbed the (lava), as a result of the momentum component of the volcano materials, transformed himself into a conical shape, to cover the surrounding area volcanic ash, gases, leading to the formation of clouds of black, and when it arises volcano rushing lava in the form of hot liquids, and incendiary, melt the high degree of heat anything in its path, and submerge it completely, so it is always advised people living near the same volcanic activity areas high to stay away and avoid going to the whereabouts of volcanoes, to move away from danger.

the Number of volcanoes ready to explode in the world up to 800 volcano, more than half of them in the Pacific region, dubbed the (Ring of Fire), and explode them in every day 10 volcanoes, but they do not pose a threat to human life, and in the last periods of time exploded around 200 volcano, ruled the lives of many people.

How does it affect volcanoes on Earth's surface.

There are many factors that explain the impact of volcanoes on the Earth's surface, including:

The rush of volcanic material: lead to impact directly on the surface of the earth, because the earth's crust do not bear the high temperature of volcanic material, which leads to fragmentation, changing surface cover component to it.

 Eliminate Bacteria: helps volcanoes in the elimination of some types of bacteria, especially producers of methane.

Release of sulfur dioxide gas: this gas helps to cool the atmosphere of the planet indirectly.

Renewal of the earth's crust: by magma, consisting of: oxygen, silicon, aluminum, iron, calcium, and many other chemical compounds, and this contributes to increase soil fertility.

Power: assisted hot material emitted from volcanoes to generate electricity, by using it as fuel to run generators.

Water heating: the presence of volcanic centers on the appearance of lakes, springs and hot water, used in the treatment of some things contributed.

 Types of volcanoes

 Volcanoes are divided into three types, namely:

Active volcanoes: Volcanoes are issued by crater gas emissions, or lead to some light earthquakes, volcanoes and is considered ready to explode, especially when increasing the pressure on the lava inside them.

Volcanoes static: the volcanoes that do not raise any moves indicate that it will explode, but are considered very serious; because it could explode at any moment.

Extinct volcanoes: it is volcanoes that failed to explode last ten thousand years, and is unlikely to explode; because they have got rid of all the magma inside them, leaving only surround cone, which indicates that it was one day bear all the characteristics of volcanoes.
