Volcanoes Are A Volcano

This is because when Mother Earth moves, people all across the world will feel it. There are many dangers that the Mother Earth and its geology present to human life. These things lay resting, waiting to be awakened. Things such as tornadoes, tsunamis, hurricanes, and even earthquakes are the very things that affect people in a way that changes them forever, whether it is by taking a life or destroying a home. All of these things are very destructive, but none like volcanoes.

Volcano: A hill or mountain formed around and above a vent by accumulations of erupted materials, such as ash, pumice, cinders or lava-flow. The term refers both to the vent itself and to the often cone-shaped accumulation above it. (Scarth, 1994.) This definition can do Mt. Vesuvius no justice.

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

The gas is made up particularly of steam, but may also include carbon dioxide, nitrogen, sulfur dioxide, and other gases. Most of the steam comes from a volcano's magma, but some steam may also be produced when rising magma heats water in the ground. Affects on the living population of the area eruptions pose direct and indirect volcano hazards to people and property, both on the ground and in the air. Direct hazards are pyroclastic flows, lava flows, falling ash, and debris flows. Pyroclastic flows have hot ash, rock fragments, and gas in them.

Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US.

Volcanoes have been around for many centuries and will continue to exist for many more to come. Many people have their ideas of what they believe volcanoes are. Most believe that it is basically a mountain that shoots out lava, destroying anything and everything nearby. This assumption is actually proven accurate. Volcanoes are considered one of the most dangerous natural disasters; they can erupt suddenly, destroying everything in its way.

Volcanoes can be really, really dangerous. It can animals, and plants. In a volcano eruption hot lava shoots out of a volcano. After a volcano eruption lava cools off. After the lava cools off it turns into solid rocks, which are called “Igneous Rock”.

Volcanoes are very dangerous and can cause harm more than by its lava flow. Things that volcanoes cause in addition to the lava flow are ash flows, lahars, mudslides, and tsunamis. Lava flows are exactly what it says, flows of hot lava. This lava is hot enough, between 500 degrees Celsius and 1400 degrees Celsius, to burn through practically anything. Ash flows, or pyroclastic flows, are just like lava flows but pyroclastic flows are just flows of fast moving hot gases and rocks.

When the magma erupts from volcano then it’s called lava. Basically, volcanoes can be found in places where the tectonic plates are diverging or converging.... ... middle of paper ... ...Seismometer can determine if earth quack are migrating toward the surface. Also, some people monitor volcanoes by constantly mentoring gases, which comes out of fumaroles. Additionally, some recent advance technologies can determine a n accurate topography fro the data satellite. Despite of all the huge devastations caused by the volcanoes, it can directly or indirectly produce mineral such as, gold; is close companion with volcanoes and can be find in three environments: in greenstone belts, porphyry deposits and epithermal deposits.

A volcano I an opening in earth's crust, by molten rock and gas.Most of the Earth's volcanoes are located around the Pacific Ring of Fire because that the location of most of the Earth's subduction zones.When lava erupts it is made up of a slush of crystals, liquid, and bubbles. The liquid freezes to form volcanic glass. Chemically lava is made of the elements silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, potassium, phosphorus, and titanium. There are 4 different types of volcanoes.There are Extinct, Dormant, Active and Mud volcanoes. The most popular volcano an Active Volcano.
