shipwreck photos taken by the Coast Guard are thought to be of ships that were sunk during the heyday of the Great Lakes. Since then, the economy of the Great Lakes region has transitioned to tourism, including shipwrecks. At the Fathom Five National Marine Park (http://www.pc.gc.ca/eng/amnc-nmca/on/fathomfive/index.aspx) in Ontario, snorkelers can get the chance to go diving around some of these aging marine wonders. Two of the ships have already been identified. First up was the 121-foot…
Glaciers are one of the most vital physical features we find on the planet that regulate many of its natural systems ranging from the Earth’s oceans to the atmosphere. Glaciers cover over ten present of the worlds surface area and store roughly seventy-five percent of the world’s fresh water supply, making it an essential component for the planet’s hydrologic cycle (Bennett, 2017). Throughout recent geologic history, glaciers have had a profound effect on the landscape, topography, and climate…
Located in northeast Oregon is the Wallowa Mountains, which contain a rich and understudied glacial history. In order to quantify the number of glaciation stages that have occurred in this locality I will examine twelve lateral moraines that border Wallowa Lake. This beautiful lake stretches 3 and a half miles north to south with a large, bordering moraine on each side and a terminal moraine at the north end. On the west side of the lake there are four moraines and on the east there are eight.…
Wonders of Olympic National Park “The land must not be sold permanently, because the land is mine and you are but aliens and tenants. Throughout the country that you hold as a possession, you must provide for the redemption of the land.” (Leviticus 25:23-24NIV). The National Park Service preserves unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations. The Park Service cooperates with…
Introduction The Tasman Glacier is located in the heart of the Southern Alps, in the South Island of New Zealand. Tasman Glacier is New Zealand’s biggest glacier and therefore is an attraction. However, the Glacier has been retreating due to a number of processes which are operating. For example, between the years of 2000-2006, the Tasman Glacier had retreated at approximately 54 metres per year (Robert C. Dykes, Brook, & Winkler, 2010). The aim of this research was to gain an understanding as…
though people cannot do much, we can all take part in taking responsibility in improving the environment. Ehrlich’s writing urges people to do things that can slow down global warming effects and prevent more harm to ecosystem by showing readers glacier that melt in fast rate due to increased industrialism by humans. Gawande’s article helps me to understand that pollution not only can damage the earth, but pollutions can have direct effects on humans as well. He’s article of “The Cancer Cluster…
America is at its normal position, north of the equator. The glacier that covered the Ice Age was the Laurentide Ice Sheet. Before the Ice Age, there was a valley called the Hudson Valley. During the Ice Age a glacier scraped through the rock, which gouged out 240 meters of rock. The sediments got removed from their previous location and deposited in a huge pile, a terminal moraine in Long Island. The sediments acted as a dam when the glacier melted, which trapped glacial melt water, which…
GG310 OCEANOGRAPHY Evaluate the geological evidence for so-called ‘Snowball Earth’ glacial episodes in the Precambrian and the hypothesis that these episodes were critical in the evolution of complex life. Introduction The importance of this period is that multicellular evolution began to accelerate after the last glacial ended.refbookpage829.The term Snowball Earth refers to the hypothesis that in the distant past, specifically the Cryogenian period (850-630 million years ago), the earth’s…
8. ice cores Ice cores in areas such as Greenland, Antarctica, and other areas that are cold allows the snow to accumulate over the years and each new layer of snow compress the snow into ice. Though in these ice cores are air bubbles that contains a sample of the atmosphere during that snowfall. This allows climatologist determined how the climate has changed over time and reconstruct the temperatures of the time period and see how carbon dioxide have influenced the earth climate. With the air…
This paper will focus on the Patagonian Ice Field and how global warming is affecting the glaciers as well as the affect the glaciers have and will have on the rest of the world. To begin I first must explain what a glacier is. A glacier is an immense field or stream of ice, formed in the region of continual snow, and moving slowly down a mountain slope or valley, as in the Alps, or over a large surface area, as in Greenland. They are formed over many years when snow is incessantly compressed…
