This is a serious issue that is already affecting the environment and its effects will only worsen. With any issue, there is conflict and controversy surrounding this topic. There is controversy between people who agree that global warming is a serious issue and those who think otherwise. There is also conflict between people who think global warming will fix itself and those who think…

There are some who claim that hydraulic fracturing is too risky and should be banned. Hydraulic Fracturing is vertically drilling into pockets of oil or natural gas and then horizontally angling the drill so as to maximize the amount of energy that can be freed. This method has been associated with environmentally negative impacts, such as air pollution or drinking-water contamination, on surrounding areas at drill sites. While there is risk involved with drilling for oil and natural gas, it is…

Carbon Dioxide on Antarctica The objective of the article is going in depth how carbon dioxide effects the Antarctica. According to Student Science sources having higher amounts of Carbon dioxide in the Antarctica causes the environment to cool. Carbon dioxide absorbs and creates radiation stated in the article. The Carbon dioxide blocks radiation from surfaces. The article doesn’t provide necessary evidence because the article is mostly talking the Antarctica climate not how carbon dioxide has…

4. EVALUATION OF DIFFERENT MODELS: Advantages and disadvantages There are many advantages and disadvantages when it comes to the electrification of transportation. Mainly when it comes to the everyday usage of small/ personal cars. Some of the advantages notes are first of all, and most importantly it reduces greenhouse gas emissions. In other words, it doesn’t burn fuel nor does it release pollutants into the atmosphere; therefore the use of this transportation method could be beneficial for…

Water mist and water sprinkler systems are beneficial in residential areas because only water is used to eliminate fire. The systems are equipped with a heat sensing bulb, pipes, and nozzles that release water by pressure. Depending on the nozzle used, either large or small droplets of water are dispersed over the fire. The water mist and water spray systems are automatic, which means that it does not require the presence of humans to perform its duty. Since water is released in a droplet…

There are many positives from tourism in Antarctica. People go there to see the beautiful sites such as glaciers, icebergs and other wonderful landscapes in Antarctica. These sites are very pleasing to the eye and mean that business’ get more money from all the tourism there, and since the number of people is increasing, these companies will, therefore, get more money and be more successful over the years. This is a more ‘business’ related positive to why people visit antarctica. Also, it's a…

Another place that I’ve been to recently and admired its geographical landscape is Mount St. Helens. The eruption on May 18, 1980 caused a monumental change in its geography, altering it to a point where it was unrecognizable. The current landscape is a combination of both aggradation and degradation caused by the rockslide debris that displaced the water of Spirit Lake, producing gigantic north part of the lake. When the water returned to the lake bed, it brought with it trees and soil in…

It is concluded that Yellowstone will someday erupt again however, it might not be in the near future. With the myriad of tourists that visit the National Park every year, they had to be sure that it wouldn’t explode soon to ensure people’s safety. Geologists have found that the ground around where the volcano is, is now swelling. The swelling indicates that the underlying magma chamber is refilling once again. But people have other questions, how was this volcano formed? Usually volcanoes…

1. Introduction 1.1 Literature Review “Land cover refers to the physical and biological cover over the surface of land, including water, vegetation, bare soil, and/or artificial structures” (Ellis, 2013). While, land cover change often means the modifications of Earth’s surface by human activities. Although, human have modified land for thousands of years for food, constructions or other things, the current rates, extents and intensities of land cover change are far greater than ever in…

The BBC stated in the article What is fracking and why is it controversial? that “Hydraulic fracturing, or fracking, is a technique designed to recover gas and oil from shale rock. Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside.” To be more specific, oil companies drill into the earth to extract gas from rocks using a high pressure water mixture. The water mixture includes gallons of water, sand, and…
