    A volcano erupts, and lava spews everywhere, burning every living thing it touches. By the time the eruption is over, not a single blade of grass is still living in the area. Volcanoes and their magma have always been viewed as chaotic, uncontrollable objects. But what if humans could use them for their own advantage? Geothermal energy is energy from Earth’s heat. Geothermal energy has some advantages over other types of energy. One is that it is available over 90% of the time compared to coal plants

    on the earth’s crust. The rupture leads to a pool of molten magma, near the core of the earth. When the earth’s crust ruptures, pressure builds up, resulting in an eruption occurring to release the pressure. Toxic gases and rocks shoot up through the opening, overflowing the air with hot lava fragments. This can bring floods, avalanches, and can even provoke tsunami and earthquakes. How are they formed? Volcanoes are created when magma from within the Earth's crust rises to the surface. At the

    Volcanoes are mountains with a large pool of magma. When pressure builds up the magma and lava spews out, this is called a volcanic eruption. So, how are volcanoes formed? Volcanoes form in destructive and constructive areas on Earth. They form when plates in Earth’s core (tectonic plates) force molten rock, gases and ash to Earth’s upper mantle. The magma lives in the Earth’s crust. Magma is made from rock and gases. When two tectonic plates collide they push magma to the Earth’s surface and as a result

    extremely high temperatures, it melts ( magma) , and builds up alongs with other gases and rocks. The magma then rises up the volcano, until it reaches the volcanic vent, where it erupts. Once magma reaches the surface of the volcano, it becomes lava where it flows down the volcano. Volcanoes usually occur near or in the middle of major tectonic plate boundaries

    similar to those in Hawaii. There is a presence of basalt as well as the old rhyolite of Krakatau, making Anak Krakatau a chemically complex volcano (Shoemaker). As denoted in the geochemical section of this paper, Anak Krakatau is next in a series of magma types, or is slightly differentiated, and is a significantly active volcano with enumerative degassing events. Eruptions include frequent pyroclastic flows XI. Conclusions Overall, Krakatau was one of the most infamous and devastating volcanic eruptions

    oceanic plate and a continental plate. When the denser oceanic plate subducts beneath the less dense continental plate, solid mantle material melts at the subduction zone. This forms magma that is kept in a magma chamber. Pressure in the magma chamber builds up over time and when this pressure is released, the magma rises through the earth’s crust to cause volcanic eruptions. The lava from the eruption cools to form new crust and the layers of ash and lava form the volcano. Aerial Volcano is an

    Volcanoes are magnificent and powerful land features. The magma erupts from the Earth forming islands, cooling to form rocks, and changing the landscape on eruption at a time. They can erupt at any time! Since volcanoes are dangerous we have developed technology to detect these impressive explosions. Since Hawaii was formed by a volcano when you visit Hawaii you are standing on cooled lava! There are 3 different stages a volcano can be in and 2 very different types of explosions that can happen.

It’s still an active stratovolcano and sits on a triple junction of tectonic movement. Fuji is approximately 100km (62 miles) from the largest city and the capital of Japan, which is Tokyo. The last time Fuji erupted which was between 1707 and 1708, volcanic ash fell
