The three major types of volcano

Back 11

Stratovolcano, Shield Volcano, Cinder cone Volcano

Front 12

Is formed by highly viscous or thick, slow moving lava. it has steep upper slopes and relaxed lower slopes. Small crater at its summit, and is packed with a large reservoir of magma caused by the heat and pressure from tectonic plate movements. When they explode, an area of the volcano may collapse, forming a larger crater ad depression called a caldera. Most volcanoes in the pacific ring of fire are this type of volcano.

Front 21

May have been formed from eruptions thousands of years apart, layered lava and volcanic materials, or composites of more than one vent. During an eruption, lava is spewed out, followed by ash and pyroclastic materials which flow down the sides of the summit. Afterwards, thick lava flows out and traps ash and other materials on the steep slope. Examples of this volcano are Mayon Volcano, Mt. Pinatubo, Mt. Kilimanjaro in africa, Mauna Loa in Hawaii, the highest volcano on earth, Mt Vesuvius in Italy, noted for destroying the ancient city of Pompei, and Mt. Fujiyama in japan
