It states that “volcanoes form mountains, super volcanoes erase them; Volcanoes kill plants and animals for miles around; super volcanoes threaten whole species with pure extinction by changing the climate across the entire planet. In order to assess the meaning of a super volcano, we must look at the different impacts it can have on the climate, how they are known for flaring up, the most current form of measurement, and even a little bit of history to compl... ... middle of paper ... ...lcanic Area, South America: Evidence from InSAR."

All of these things are very destructive, but none like volcanoes. A volcano is a mountain or hill that has a crater through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust, as stated by Webster’s dictionary. They are formed when magma within the Earth's upper mantle works its way to the crust. This accumulates and forms a magma chamber. Over time this grows larger and a volcano is created.
Volcanoes obtain their energies from such movement and pressure. Volcanoes form at the boundaries of these plate where two types of movement occurs, two plates will collide with each other or the plates will move apart from each other. Some of these plates layers are cooled and are made up of rigid rocks. The affects on the landscape is lava that releases onto the Earth's surface. When that lava comes to the Earths surface, it is red hot and sometimes the temperature is more than 2012 degrees Fahrenheit.

In 79 A.D. its catastrophic eruption destroyed the cities of Pompeii and Herculaneum, killing thousands. The eruption of Mount Vesuvius buried those cities under numerous meters of ash . Volcanoes seem to have two jobs.
Nature’s Fury: Volcanoes Volcanoes are one of the most terrifying and spine-chilling natural calamities that is known to mankind. It is a constant reminder of the fearsome power of Mother Nature. A volcano is a mountain with an opening at its tip and contains molten rock known as lava. Volcanoes erupt when the pressure within the volcanic mountains increases. Hot gases, fragments of rock, soil are all thrown out due to the pressure.
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.
Ash flows, or pyroclastic flows, are just like lava flows but pyroclastic flows are just flows of fast moving hot gases and rocks. This kills more people than lava flows actually do because pyroclastic flows move fast while lava flows move in a slower manner. Lahars are destructive mudflows on the slopes of a volcano. This type of mudflow carries pyroclastic materials, rocks debris, and water. Tsunamis are also caused when volcanoes erupt.
One part of a volcano is the magma chamber. According to Universetoday.com it states that the magma chamber is where the molten rocks (magma) are stored. Lava is the hot magma that is outside of the volcano according to Universetoday.com. Universetoday.com said that the main vent is the weak point of the volcano where the lava is about to shout out. The ash cloud of the volcano is the smoke or rocks that shoots out, containing many dangerous gases like carbon dioxide, this smoke could be as dangerous as lava.
Volcanoes are made up of different layers of the earth. Many things can occur after a bad eruption. There are 3 main things that can happen. They are Hot Springs, Calderas and Mud spots.Hot Springs occur when magma beneath the surface heats up the water in the cracks overlying rocks. Calderas happen when a massive blast of lava empties a volcano's magma chamber and causes the volcano to collapse on itself.
