Descriptive Essay About Volcano

There are 20 volcanoes scattered throughout northern, central, and southern California: Medicine Lake, Mount Shasta, Brushy Butte, Twin Buttes, Silver Lake, Tumble Buttes, Eagle Lake, Lassen, Clear Lake, Mono Lake, Mono Craters, Long Valley, Inyo Craters, Mammoth Mountain, Ubehebe Craters, Golden Trout Creek, Coso, Lavic Lake, Amboy, and Salton Buttes. Some of these volcanoes are active, while others are not. A majority of the volcanoes are inland, with Clear Lake Volcano being the furthest west, located near Sacramento and San Francisco. (Refer to figure 3 to see main .k California volcano locations.)

It is believed that this volcanic area was caused by a localised hot spot within the Pacific plate. A concentration of radioactive elements inside of the mantle may have caused this hot spot to develop. The hot spot is stationary so as the Pacific plate moves over it a line of volcanoes are made. This is more proof that the Earth’s crust is moving as suggested by Wegener.

analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks)

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The location of the volcano is also important. If it is situated on a constructive plate boundary then it is generally less explosive, and therefore poses different threats to volcanoes situated on a destructive plate boundary. The volcano may also be situated on a hotspot like in Hawaii, where the eruptions aren’t very explosive. Volcanos which aren’t explosive can pose other threats to lava flows though, such as dangerous gases being released. Like in Lake Nyos, Cameroon where 1700 people died.

The RIng of Fire is located on the coast that surrounds the Pacific Ocean, there are 452 volcanoes and that’s 90% of all the volcanoes. Only 75% of the volcanoes are active to this day. In my paper I will mostly be talking about the location, creation, and the volcanoes in the RIng of Fire.

Most of Earth’s volcanoes are located in the _______________ around the Pacific Rim just beyond the oceanic trenches, where magma, which is less dense than the

The Earth’s outer crust is made up many tectonic plates that move over the surface of the planet. When the plates come collide, volcanoes will form sometime (National Ocean Service). Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot” (National Ocean Service). A hot spot is a plume of magma or molten rock that rises from within the Earth then reaches the surface forming underwater volcanoes which may grow tall enough to

The mythology of the Aztec peoples, which dominated central Mexico in the 1400’s and early 1500’s, described a universe of greatness and fear. In this Mexica civilization, volcanoes had a deep spiritual as well as strategic military importance. The legend of the volcanoes, Popocatepetl and Iztaccihuatl, is no different. The Aztec mythological explanation for the two volcanoes is a story of love and war. In this paper, I will describe the legend behind these two natural locations and its correlation with the spiritual and social importance of volcanoes to the Mexica people at the time.

The active volcano that I chose to research is Popocatepetl volcano. Popocatepetl volcano is an active volcano located in Mexico. The volcano is oftentimes referred to as “El Popo” by many Mexicans. El Popo is a composite cone volcano. Being a composite cone volcano, El Popo is characterized by a steep cone shape, which was created by many composite layers of material pouring out over numerous eruptions. The lava that comes out of El Popo is extremely viscous. The highly viscous lava does not travel very far, and typically cools down rapidly. Scientists believe that El Popo is about 730,000 years old. It has erupted more than 15 times since 1519. In 1994 El Popo produced gas and ash, which caused nearby towns to evacuate. The toxic

Mount Vesuvius is one of history’s most recognizable Volcanoes, as each of its eruptions have gone down as a significant event in geologic history. The events that transpired during and after these eruptions have shaped the way scientists and people view the sheer power that these volcanoes possessed. This report will take a look at Vesuvius’ most prolific eruption in 79 AD. The geologic setting of the mountain, precursor activity, and the impact the eruption had on the surrounding populations and towns will all be detailed. Along with these details, this report will also look at the further history of Vesuvius’s explosive past by detailing its eruption cycle. Finally, the current state of Vesuvius and the possible danger

Ash plumes and steam rose into the bright blue sky as the underground earthquake shook the land and rattled windows all across the eighteen mile town. As the jet circled the island, in view of lovely beaches and emerald water, looming over this lush paradise was the screaming volcano. Volcanos erupt when the pressure inside of them becomes so great that the magma surges up and forces its way out. An exploding volcano can rip apart a mountain in just seconds, when the eruption is over, a landscape is changed forever. The united states is home to more volcanos than any other country except Indonesia, and Japan. The majority of these volcanoes are in Alaska. Until recently, there was no way to predict when a volcano would blow, although volcanoes give off many warning signs before they erupt. Including smaller earthquakes beneath the volcano, slight inflation, or swelling. The rising magma eventually causes the solid rock to break, sending earthquake signals. Most volcanoes give warning signs beginning weeks or months before they blow (Lindop).

When the sun slowly peeps over the range of mountains, birds shake the morning dew off their feathers and give a cheerful song that would lift even the most sorrowful of spirits. A light fog wraps around the mountain range, reaching to touch every bit of life thriving there. The slight chill in the air is enough to give a gentle shiver, but not enough for the need of a jacket. A breeze tickles the trees, making their leaves shake and sway with laughter. Sunlight seeps in past the thick canopy of branches with hopes of being able to reach the damp mountain earth. The mountains are the best place to live to be relaxed, see the most beauty, and never get bored.
