Around the world there are many different types of volcanoes, but there are only three main types, Composite, Shield, and Dome volcanoes. A Composite volcano is also known as the Stratovolcano, this volcano is built by many eruptions that have happened throughout the course of history. Composite volcanoes are tall cone shaped mountains. These volcanoes erupt in different ways at different times. Shield volcanoes are the largest volcanoes on earth. These volcanoes are built almost entirely of lava. Shield volcanoes are produced by gas and heat from the earth’s ...

...different types of gases start to exit the vent of a volcano, some of these gases can be harmful because they are extremely toxic. Therefore, you can easily find out when a volcanic eruption is about to occur because of the signs or sudden changes that the volcano gives out about weeks or months before it erupts.
Throughout the course of history many major volcanic eruptions have occurred. Those volcanic eruptions have caused starvation, tsunamis, ash flows, mud flows, and many diseases. For example Mt. Tombora erupted in Sumbawa Island, Indonesia in 1815, and is one of the highest ranking volcanic eruption in human knowledge. The eruption produced tsunamis with waves about 10 meters high. The eruption was so loud that it was heard from more than one thousand two hundred miles away and it killed about seventy one thousand people. Mt. Tambora is still active today.

- Imagine yourself feeling hopeless; you can smell the sulfur in the air, tickling the back of your throat. The ground rumbles and sways as if the Gods themselves are furious and want to unleash on this small city. Panic all around in the streets, women screaming, children running scared in the streets, men hopelessly trying to save their families from certain doom. This is what it would feel like if one lived in the Italian city of Pompeii in 79 A.D when Mt. Vesuvius had, perhaps the largest volcanic eruption for those times....

- Why doesn’t Australia have volcanoes and New Zealand does. Australia doesn't have any active volcanoes because Australia is on one single tectonic plate (see picture) There is currently around about 57-65 volcanoes in Australia and out of these, only one is active. No eruptions have been recorded in the past century. Volcanoes occur on the tectonic plate boundaries. Because Australia is in the middle of the Australian plate and it is impossible for any new volcanoes to form. There is evidence that Australia may have been on a faultline due to the many dormant volcanoes throughout the country.... [tags: tectonic plates, erupt, ashfall]

- 1. Despite being in a dangerous location, the slopes of volcanoes can be attractive to people setting up homes due to the rich, fertile soil 2. According to scientists, in the last 500 years approximately 20,000 people have died as a result of volcanic eruptions 3. A volcano is landform (generally a mountain) where, during an eruption, ash, gas and molten rock (magma) escape through the Earths surface 4. Approximately 1 in 10 people in the world live within danger range of an active volcano 5. Located on the planet Mars, Olympus Mons is the largest volcano (and mountain) in the Solar System....

- “...99.9 per cent of all [species] that have ever existed are now extinct.” (Benton 1) After one hundred and sixty million years of domination, the reign of the dinosaurs ended in fire and ice. Sixty five million years ago, the largest volcanoes in the history of the Earth erupted across what is now India, effectively annihilating the dinosaurs by spewing out noxious gas and ash, that effectively blocked out the sun killing off most vegetation and breaking the food chain, leaving the dinosaurs to starve....

- VOLCANOES AND THE EARTH SYSTEM EFFECTS OF VOLCANIC GASES Most of the gases in the atmosphere originally come from the Earth's interior. Gases within magma are dissolved because of high pressures beneath the earth's surface, but reduced pressure at the surface allows dissolved gases to expand and escape. When a volcano erupts, gases such as sulfur dioxide, carbon dioxide, chlorine, argon, sulfur, carbon monoxide, fluorine, and water vapor escape into the atmosphere. Although many of the gases emitted during a volcanic eruption can be helpful to the earth, a lot of the gases can be disruptive to the earth system.... [tags: Geology]

- Affects of Volcanoes The plates which are about 20 miles thick, make up the earth's crust and are a chief cause of volcanic activity. These plates are always in motion. They move very slowly, however some at times bump in to each other. These movements put a lot of pressure on the surface rock. 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....

- Hawaii is comprised of many different islands which mean it has many different volcanoes located on its surface. The Big Island of Hawaii, the largest island of Hawaii, also holds the most volcanoes out of all the other islands. It has six different volcanoes located on: Mauna Loa, Kohala, Lo 'ihi, Kilauea, Mauna Kea, and Hualalai. The main topic that this paper will primarily be focused on is that of the largest volcano, Mauna Loa. However, the essay will be covering a little bit of information on only three of the other volcanoes located on the Big Island of Hawaii: Kohala, Kilauea, and Hualalai....

- According to Quartz News, harmful substances known as pollution eradicate 2.4 million people every single year. Pollution is the addition of anything harmful into the environment that has a poisonous effect on humans as well as other species. There are many different types of pollution, including water pollution, land pollution, and air pollution, all of which have an extremely dangerous effect on the world and will eventually lead to global warming. Air pollution can potentially cause health problems, such as, asthma and other respiratory difficulties.... [tags: environmental issues]

- Acid rain has been proven to have damage forests, fresh waters and soils, killing insect and aquatic life-forms. It also causes damage to buildings and impacts on human health. Many people do not know what acid rain actually is. Acid rain is any form of precipitation that is unusually acidic, low pH levels, higher than normal amounts of sulfuric and nitric acid, occurs naturally and from man made sources. Forms when gases react in the atmosphere with water, oxygen, and other chemicals (what is acid rain?).... [tags: precipitation, pH levels, damage]

- Basalt is a common extrusive igneous rock, there are a large number of volcanic provinces across Southeast Australia that have been found to contain basaltic lava flows. It is likely that these flows have come from volcanic activity caused by mantle plumes from the mesosphere. A variety of dating methods have been used to date these basaltic rocks, which have been aged from the Jurassic era right up to the late Cenozoic. 1. Composition of Basalt Basalt is a commonly occurring igneous rock. More specifically however, Basalt falls under the category of Mafic Rocks.... [tags: mafic rocks, volcanoes ]
