Vesuvius no justice. Instead, I would describe it as one of the most hellish and population decimating volcanoes. Vesuvius lives…or lived! In its prime, Vesuvius covered and demolished two of Italy’s biggest cultural and artistic cities of its time. In this paper, I will be discussing volcanoes in general.
These extruded materials can affect the Earth’s structure and atmosphere. There are three types of volcanoes existent on the Earth. The most common type of volcano is a cinder cone. A cinder volcano is built from ejected lava fragments that take on the appearance of cinders as they begin to harden while in flight. (Tarbuck, 152) The structure of this volcano is determined by the shape and slope that the pyroclastic material forms as it hardens.
Mt. Vesuvius is an active volcano; however, before discussing this volcano, the deliberation of the types of volcanoes must be talked about. There are three different types of erupting lives of volcanoes: extinct, dormant, and active. (Timothy Oleson) An extinct volcano is a volcano that has not erupted i... ... middle of paper ... ... released. When it finally does release, it is volatile and is very explosive.
Calderas happen when a massive blast of lava empties a volcano's magma chamber and causes the volcano to collapse on itself. Mud spots happen when water is heated underground can release steam that forces its way to the
When that plate is pushed down it melts from the heat of the mantle and turns to magma. Then the magma from the mantle pushes up through that space where the plates met and the pressure builds up until the volcano
Volcanoes then erupt because of their bouyancy and gas pressure. On account of this buoyancy, the hot liquid magma rises toward the surface through the more dense rock. Gas pressure from within the magma also exerts a force on the surrounding rock. This cracks the rock, located above the magma, and then moves into the crack. This process is repeated over and over again until the magma reaches the surface.
One type of volcanic eruption is when magma rises through the surface and comes out of a vent as a lava flow this is called an effusive eruption. Magma is torn to bits called pyroclasts as it makes it’s way to the surface this is an explosive eruption , according to volcano.oregonstate.edu . Volcanoes are destructive in their own way
What are volcanoes? A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. In another definition it is a mountain That has a passage to the underground molten seas of rocks , when the pressure increases on this molten seas it causes eruption gases and molten rocks shoot up through a hole in the top of the mountain and fill the air with lava fragments . This eruptions cause a leatral blasts ,lava flows , hot ash flows and many other disaster .
Hot gases, fragments of rock, soil are all thrown out due to the pressure. Lava and rock fragments spill over and the air fills with smoke. The lava, ash, and noxious gases are released at a high temperature in the range of 2,100°F (1,150°C). Avalanches, mudslides, hot ash flows, lava flows are all common disasters which follow a volcanic eruption. Volcano eruptions have in the past destroyed
Natural Disaster Pamphlet - Volcanos What are Volcanoes? A volcano is a opening or rupture 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.
