Mt. St. Helens national park Mt. St. Helens mainly situated in Washington constitutes one of the most calamitous volcanic mountains in US besides being a fascinating tourist region (Samson 310). Hence, being a global envy due to its 400 view sites meant for tourists who normally frequent the region to have a glimpse of the mountain besides its rich ecosystem that encompasses wildlife. Its crater resembles the shape of horseshoe, which adds to its beauty for tourist attraction especially when viewed from far. The mountain in 1980, due to its worst ever volcanic activity rated as the most deadly incident that occurred in US (Samson 312). The Disaster yielded both to economic and life loss where fifty-seven people died besides obliteration of 250 homes and the region’s infrastructure.
Additionally, the mountain also comprises of crater glacier that has an ice thickness raging amid 1 to 2 meters, thus making it young geologically. The mountain besides having glaciated valleys during eruption incidences, it comprises of three rivers namely Toutle, Kalama and Lewis where their purposes entail recreational and power generation (Samson 17). For illustration, lewis, which feeds three dams mainly for hydropower production, is helpful to the park itself and society.
The park has its contribution regarding environmental degradation setbacks that have affected the area besides humanity and wildlife. The frequent eruption incidences witnessed on the mountain comprises production of obnoxious gases like Chlorine and HFCs that contribute to the destruction of ozone (GVP). However, this feature to numerous populaces may not be clear, but scientifically it is evident that volcano eruptions normally comprise of harmful gases that enhance global warming. This is due to the obliteration of the ozone layer that is liable for filtration of harmful solar rays to human. The eruptions besides destroying the surrounding forest cover, it also yields to wildlife destruction that adorns the mountain.
The destruction inevitable because no known human efforts or any known remedy can salvage both the forest and wildlife. According to some concerns emanating from environmentalists, they stated that, the augmenting volcanic ash might yield to prolonged negative impacts like freezing, crop destruction or horrific hazards (GVP). This is an indication that, in the future these occurrences may render the region unfruitful because the economic factors that mark the place mighty become extinct. Its eruption yields to burning of numerous insects hence destroying ecosystem that abound the area besides rendering the roads that border the region impassable.
The lava flow emanating from the mountain over time once it solidifies geologists have associated it with underlying metals that characterize St. Helens mining district (USGS). Despite the region having metals deposits, its quantity is immaterial and normally lies in the south-central section. This implies that the insignificant deposits are unreliable for mineralizing stability of the state’s economy. To the date, of all the metals explored in the region, it is only copper that has proved to have significant quantities. The region also has rocks that emanate from the solidification of the past flowing lava, which comprises layers of varied ages. Mainly, the rocks encompass volcanic siltstones and andesitic.

...? Geology Introduction Ores are types of naturally existing rocks having minerals and metal components. It is also known as a metalliferous mineral, which means it is composed of metals and iron components, whose nature and form is largely dependent on the amount of individual components forming it (Green & Basher, 2009 p 124)1. After miners have extracted the ores from the ground, they then refine them using other substances to remain with the valuable elements. Extraction and processing of these iron ores is an expensive venture but it largely depends on mineral concentration and the form it occurs in the ground. In order to establish if a mine is commercially viable, the engineers evaluate if it has substantial mineral...

...Overview There has been growing fear between many scientists that human interferences are modifying the capa of ecosystems to endow with their goods (e.g. freshwater, food, pharmaceutical products, etc) and services (e.g. purification of air, water, soil, sequestration of pollutants, etc). This can lead to ecosystem disorder and bear a significant impact on humans and animals as well as plants, in a variety of ways and through complex pathways. These are moreover modified by the population's existing vulnerability and their future capacity to execute adjustment measures. Because of these concerns, the prominent changes, at least many of it, occur so in the arctic region. The basis for this is strong positive feedback associated... There has ...

...down the waxy coating which normally acts to prevent too much water loss and helps protects the leaves from diseases, pests, drought and frost. It is clear that something needs to be done about the chemicals we, as a species, are dumping into the air we depend on for life. There are, fortunately, several possibilities by which we might address the issue. Increased attention and support for alternative renewable energy sources is an important first step. Reducing the number of combustion engines on the roads as well as the extent of power supply plants dumping pollutants into the air as more and more energy-producing houses feed into the grids rather than pull from them would all contribute toward a better, brighter, cleaner...

...against Americans. I then read the FAQ sheet at the end of the quiz to discover why my own frugal lifestyle needed 2.77 Earths to sustain it. I found a partial answer in learning that some environmental impacts for a city or nation are averaged among all of the people. For example, the impact of transportation infrastructure is averaged among all of the citizens even if I personally do not use this infrastructure. This could lead to a slightly higher score. On the other hand, it is made clear in the article by Venetoulis and Talbert that many of the factors, such as carbon sequestration and true cost of pollution is not factored into many ecological footprint calculations, so the number of Earth’s needed may be much...

...Geology Earth itself has had its share of unfathomable mysteries and the universe with all the heavenly bodies occupying it appears vast in mystery and beauty. For one, the exhibition via the Cullman Hall of the Universe is particularly striking. Viewers like me are chiefly left with an impression that universe indeed is ever-expanding. At that moment, I was brought to ponder about the size of God who is behind such an incredible idea which reflects the great astrophysical value of matters in the outer space. During this stage, the sight of the exhibits drew me to the interest of imagining how quantum particles could have possibly been of the evolution process of the cosmic materials comprising the universe.

Calcite, Marcasite and Galena

... CALCITE AND MARCASITE ON GALENA. Calcite is a mineral that is formedfrom the reaction of calcium and carbon to form(CaCo3), and occurs in granular or compact shapes, exhibiting a white color in pure form or grey, blue ,black, red ,yellow or orange if it has some impurities. Due to its carbon nature, it can easily be reacted or dissolved with most acids or water to release a carbon dioxide gas Its retrograde solution thus fairly soluble in hot water and subject to the favorable conditions of precipitations will give a cementing product to the apparent rock and a porosity on dissolution and its removal from the rock on dissolution. The calcites are usually transparent or opaque and have traces of phosphorescence... CALCITE AND MARCASITE ON ...
