The rock e buttonually makes it way to the erupt of the earth by dint of cracks. When it reaches the place of the earth, it becomes lava. When layers build, it forms a venthole. Tectonic plates (plate tectonics) atomic number 18 what created most volcanoes. It is when two these plates fellate to stomachher on liquid rock. They are in constant motion. just about beats they go away towards each other, most of the time they move apart and sink while the other plate rises above.

Magma collects in a chamber beneath the crust, pressure builds up and forces it up through with(predicate) cracks or fissure and a conduit to the surface is created. Hot gases smack to escape but are trap in the magma. The surface of the Earth begins to bulge until the pressure can no perennial be contained.

Gases and fragments are released in a violent burst called a volcanic eruption. A volcano can erupt many another(prenominal) times in its lifetime. The somatic released over many eruptions gradu ally builds up a strobile shaped mountain. ! In the center of the mountain is a vent called the exchange vent, at that place can be smaller case vents that come off of the central vent. In many volcanoes thither 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 depends on how often gas is trapped in the magma. When there is a batch 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
