The Glacier moved south to about the middle of Iowa, and cover northern and western parts of Minnesota. It also covers the eastern North and South Dakota and ends in Iowa. Continental glaciers form by snow staying in the same spots all year and compacting and they keep growing,…
Glaciers this size are called continental glaciers. These large blocks of snow and ice once covered much of North America. Today, Antarctica and Greenland hold most of the world’s glaciers, but glaciers are found on every continent on earth. Thousands of years ago, glaciers were found in Minnesota, and as they retreated they left behind large amounts of glacial meltwater and various landforms that are still here today.…
Figure 2 shows the movement of glaciers and how they shape the land. In this case, the glaciers rounded out the land and the meltwater would have eventually formed…
Until 11,700 years ago our earth had been in the Pleistocene Epoch, incorporating an evolutionary surge that lead to Homo Habilis, who lived from about 2.1 to 1.5 million years ago(2). By the peak of this duration the global temperatures on earth dropped by about 5oC, plunging the entire planet into an ice age, creating vast glaciers miles deep that expanded across limitless amounts of land, locking hordes of water into impenetrable sheets of ice. However, this gave a few species on earth a fierce advantage, for the glaciers had taken so much water from the oceans that it managed to drive the sea level 450 feet below that of today's. This unbelievable event altered so much of the earth’s surface that it created masses known as land bridges,…
The Columbia Glacier drops down an ice field 3,050 meters above sea level, down the side of the Chugach Mountains, and into Prince William Sound. The glacier is one of the most rapid changing glaciers in the world. The glacier flows directly into the sea. When it was first discovered, the beak of the glacier went down to the northern edge of Heather Island. This island is near Columbia Bay.…
Student Name: Jinfan, Qiang Student Number: 1002688834 Course Code: ERS0101 On October 29th, 2012, Hurricane Sandy suddenly changed its direction towards the northeast coast of the USA and caused 43 dead, more than one hundred homes were burned in that night. This disaster warned people to think more about the effects of rising sea in our daily and future life. It has become to common sense that the major reason of rising sea level is our fossil-fuel-driven civilization. Burning causes carbon dioxide released into the atmosphere, the overall temperature in the earth's atmosphere increased gradually.…

The Arctic Ocean is located in the Northern Hemisphere. polardicovery.whoi.edu says, "Greenland, Spitzpergen, Alaska, Canada, Norway, and Russia surround it. It used to be called the Frozen Ocean. " The Arctic Ocean, over 5,400,000 miles in area, is a very important habitat. It has lots of animal and plant life, but people have made some negative impacts on the area.…
How and Why California coast (Pacific Coast) is Eroding faster than it should and the effect of it. I chose the California Coast or the Pacific Coast as it is one of the most popular coasts in the world. California has always been in the news for various natural disasters like forest fires, earthquakes and now Coastal erosion. California is also the World’s IT capital where all the famous companies like Google, Facebook, Apple etc are located. Many Indians migrate to california for jobs.…
The ice sheets movement is contributed to by trickling water from melting. A phenomenon outlined by Livescience is “Most of Greenland's supraglacial lakes drain slowly when superficial streams route water into nearby, permanent crevasses or moulins (vertical conduits or shafts in a glacier). Fairly recently, however, satellite images showed that about 13 percent of the lakes drain quickly, emptying completely within 24 hours.” In 2008 there was research led by Sarah Das showing that temporary hydro-fracture could cause rapid lake drainage on a enormous scale.…
Evidence of the rising temperatures can be traced as far back as the Industrial Revolution. This began with the burning of fossil fuels to create energy in forms of gas for one’s car, and even heat for our homes. This is causing heat to become trapped in the lower atmosphere, and with rising populations across the world the…
Other studies have showed that ice in both the Arctic and in Greenland is freezing at historic levels, which could explain why the sea level rise hasn’t been as high as some organizations have predicted. It has also been shown that Greenland glaciers are receding, which is attributed to global…
The Intergovernmental Panel on Climate Change (IPCC) estimates that sea levels will raise between 0.18 and 0.59 meters (0.59 to 1.9 feet) by 2099 as warming sea water expands and mountain and polar glaciers melt. TRANSITION: After talking about some problems of global warming mentioned above, I will discuss about some main factors causes global…
Global warming and the world General Purpose: To inform Specific Purpose: To inform my audience of global warming and its impact on our planet Central Idea: The growing concern of climate change and the rising sea level due to globe warming has been a big discussion in many parts of the world Introduction I. Attention-getter: How’s the weather outside? Many of us many not this but the earth is growing hotter as the years goes by.…
David G Victor said in his book that global temperature around the world has been increasing rapidly. In the past decade, the global temperature has increased by 1 degree Celsius, due to human activities such as using fossil fuel which emits carbon dioxide in to the earth’s atmosphere. There are many ways to prevent or stop the global warming. One of the easiest…
