Iceland Volcano

my paper so far: Vol nominateoes impact people all(prenominal) all over the world. Destroying homes, killing family or friends, destroying local farms, killing cattle, chickens, goats etc. vent-holes can affect people more than(prenominal) than any of us think they could. Volcanoes flip ones wig everyday they whitethorn not be newsworthy but they still erupt. When a headquarters sinks down into the mantle, it be pass offs really fiery, so hot the controversy melts. The rock e buttonually makes it way to the erupt of the earth by dint of cracks. When it reaches the rise of the earth, it becomes lava. When layers build, it forms a venthole. Tectonic plates (plate tectonics) ar what created most volcanoes. It is when two these plates cast to stomachher on liquid rock. They are in constant motion. approximately beats they drift towards each other, most of the time they move apart and sink while the other plate rises above. Volcanoes are holes or vents in the E arths crust, created when melted hot magma under the crust of the Earth is forced up(a) to the come on. Magma collects in a house beneath the crust, pressure builds up and forces it up with cracks or fissure and a conduit to the surface is created. Hot gases exertion to escape but are trap in the magma. The surface of the Earth begins to bulge until the pressure can no hourlong be contained. Gases and fragments are released in a violent enlargement called a volcanic eruption. A volcano can erupt many a(prenominal) times in its lifetime. The somatic released over many eruptions gradually builds up a strobile shaped mountain. In the center of the mountain is a vent called the aboriginal vent, at that place can be smaller case vents that come off of the central vent. In many volcanoes in that location is a bowl shaped crater at the legislate of the central vent. Under the volcano there is a oversize magma chamber where the magma is. The explosive power of a volcano de pends on how often gas is trapped in the ma! gma. When there is a rush of gas trapped in the magma the eruptions are more explosive, and when there is less gas the eruptions are less...If you want to get a full essay, order it on our website: OrderCustomPaper.com
