Great Impact Of The Great Lakes

Out wash has small sediments sorted in layers, and Till has large sediments not sorted into any layers. Till can leave behind features like Kame, Drumlins, and Moraines. Drumlins are elongated hills of till. Drumlins can be found in Central Minnesota and/or South of Brainerd. Moraines are very large ridges of Till. Moraines can be found in West/Central Minnesota. Outwash can leave features behind like Outwash Plains and Eskers. An Outwash plain formed by melt water of a glacier. Outwash plains are important because they are very great for farming which is a huge part of America. Glaciers can leave behind features like Kettle Lakes. Kettle Lakes formed by ice chunks falling off the main glacier, causing an indent on the earth's surface. Then the ice chunk will melt causing the hole to fill up with water. Most of Minnesota’s Kettle lakes are in Moraine/Terminal Moraine

For the first paragraph we shall have a quick focus on the geological history of the area of Kalamazoo. The main deposits and formations of the Kalamazoo area where formed during the Wisconsin glaciation period. Now the deposits are actually due to two lobes during this period, the lobes are the Lake Michigan and Saginaw lobe. Kalamazoo is actually know as a “reentrant district” due to the presence of two different lobes materials. During the middle of the Wisconsin Ice Age the Lake Michigan lobe was extending southeastward, while the Saginaw lobe was extending southwest. With the meeting of the two lobes an interlobate developed between the terminals of the lobes. It is also thought that the two lobes overlapped each other. With the Saginaw lobe covering the Kalamazoo area first and then retreating while the Lake Michigan lobe then covered the area. There are also some bedrock formations in the area as well, these formations were established during

The definition of glacial lake is any lake formed from glacial origin which would include Kettle lakes, kettle lakes are small lakes made by ice blocks left there from the glacier. Some evidence of glacial lakes in Minnesota are the large amounts of iron and sedimentary rocks and sediments. There are 6 major glacial lakes in Minnesota these lakes are Agassiz, Upham, Aitkin, Duluth, Grantsburg and Minnesota if there is another one I could not find it in the articles or online. The largest glacial lake is Lake Agassiz it covered a lot of Minnesota some of the Dakotas and lots of Canada it is truly the father of all glacial lakes, or at least it was. Glacial Lake Agassiz was drained by the Mississippi (the only answer I could find) and the water went into the Gulf of Mexico. Parts of this massive lake can be found in Lake Winnipeg, Lake Winnipegosis, and Lake Manitoba and

The present configuration of the Great Lakes basin is the result of the movement of massive glaciers through the mid-continent, a process that began about one million years ago. . . . Studies in the Lake Superior region indicate that a river system and valleys formed by water erosion existed before the Ice Age. The Glaciers undoubtedly scoured these valleys, widening and deepening the and radically changing the drainage of the area (Encyclopedia Britannica )

During the Pinedale glaciation, there were two ice sheets. One of them being the Cordilleran Ice Sheet. The Cordilleran Ice Sheet was comprised of three main lobes. The Puget Lobe, Okanogan Lobe, and the Purcell Trench Lobe. The one lobe in Northern Idaho, near present day Lake Pend Oreille, was the Purcell Trench Lobe. When these sheets of glacial ice moved south they caused an ice dam to occur. J.T. Pardee states that “The evidence of icebergs, together with the apparent regency of the lake and the variable height of its surface, connect this lake with the glacial period, and readily lend themselves to the suggestion that its dam was of ice” (Pardee, 1910) This ice dam blocked the Clark Fork River which is near the boundary of Idaho and Montana. The water from the river was blocked and began to build up and formed Glacial Lake Missoula. Water

As this river of ice moved slowly over the hidden rocks, the base of the glacier grazed millions of sediments in the Earth. The after math composed of soil, pebbles, cobbles and boulders that pushed forward, smashing rocks into glacial dust. Then the climate began to warm. Melted water from the glaciers carried the soils and rocks away from the dissolving glacier, depositing its leftovers throughout the landscape. This combination of soils and rocks deposited. Then low hills, or moraines, were created across the state. Michigan's glacial drift averages 200 to 300 feet. The scraping of boulders created particles. The heaviest pieces formed ridges, which made the stream's flow in a certain direction. Lighter materials were carried further, dropping on the way as the flowing water slowed. These materials dried forming enormous, flat colored areas of sand, silt, clay creating a mixture called the outwash plains. The weight of the glacier over the Michigan basin was dropping, and the Earth began to recoil, like a sponge coming back to its original shape. The Michigan landscape began to appear. Plants began to approach on the shriveled landscape. Individual plants found a suitable growing environment near each other, which created a suitable home for

Living around the Great Lakes like we do in Michigan brings a lot of advantages. We have a great amount of water, unlike much of the United States. Water has shaped Michigan to its shape over the past thousands of years. The total area of Michigan is 96,716 miles squared. The total surface of the Great Lakes is 94,250 miles squared. Michigan is surrounded by 4 of the 5 Great Lakes like shown in figure 1. The Great Lakes include Lake Superior, Lake Michigan, Lake Huron, and Lake Erie. Water has shaped Michigan to the shape it is by many different ways. Erosion, transportation, deposition, glaciers, and manmade causes.

It began 2 million years ago, Canada and the upper U.S. were covered in glaciers. All the repeated melting and freezing of the glaciers created thousands of cavities in the Canadian Shield, which were filled with melted glacier water which created the Great Lakes (and many other rivers and lakes). In the west, there used to be a HUGE lake (Lake Bonneville) but it drained into the Pacific Ocean through rivers and dried out

The long history of the formation of the Great Lakes and Michigan start with the impact of glaciers. Throughout history, there have been four major periods where glaciers moved across Michigan, shaping and forming the land. Every time a glacier

The overall land of the Interior Plains slopes gently downwards from the west to the east. Below the surface of the Interior Plains are mineral deposits, the swamps that are on the edge of the ancients seas that once covered Saskatchewan produced plants that were eventually changed to coal which is mined today. A lot of the Interior Plains is marked up by glaciations, the glaciers left deposits that produced rounded, gently rolling landscape. The glaciers melted water formed a large lake, when the land rose the water from the ancient lake drained into the ocean and what is left of that large ancient lake are smaller lakes known as lake Winnipeg, Manitoba, Winnipegosis , and Cedar

Glaciers take part in two of the Earth's cycles hydrology and the rock cycle. When precipitation falls at high attitudes where glaciers exist, the rain or snow becomes a part of the glacier and may be stored in the glacier for up to thousands of years. Glaciers move very slow but are very important in erosion of rocks. (Lutgens & Tarbuck)

Some of Earth’s most beautiful landmarks were formed by erosion. Many beautiful places in Michigan wouldn’t exist if water hadn’t shaped the land. For thousands of years Michigan’s lands have changed with water and they still change with water today, so let’s look at some facts.

This policy memo is addressed to Congressman David Joyce who represents the 14th District of Ohio. Congressman Joyce is a Republican who could be considered a moderate conservative on an ideological scale, meaning that he is about halfway between moderate and far-leaning right (Rep. David Joyce, 2016). Issues that Joyce works toward are the economy and jobs, which is his number one priority, and is also against regulations and taxes. Joyce is heavily involved in energy with a focus on supporting the coal, wind, and natural gas industries, in addition he is against policies that may burden small businesses. The Great Lakes and environment are a priority for Joyce as he wants to protect the Great Lakes, but mainly for economic purposes. Joyce has sponsored three bills that work to protect and/or restore the Great Lakes. He has not been vocal in regards to whether or not he believes in climate change, although his stance toward coal and natural gas would suggest that he may not, although this may be solely to protect Ohioan jobs. Additional issues that he works toward are defense & national security, health care, the national debt, tax reform, veterans, and seniors (Issues & Legislation, 2016).

Glaciers are one of the most fundamental phenomenon on the planet, and much of their purpose and impact on earth has been well documented and published. Ice sheets, Ice Caps and Glaciers trap nearly 90% of the world's fresh water, and are replenished by snowfall each year. Their existence on this planet dates back 650,000,000 years and yet they are always moving, always shifting and always melting. Before, human existence and even during the brief era of humans, ice dominated all of the earth's landmass and have regulated, created and altered many of the landscapes around the world.

71 percent of the earth’s surface is made of water. 97 percent of earths water is saline water and not safe for human consumption. This leaves just 3 percent of earth’s water as fresh water most of which is icecaps and glaciers. 68 percent of the fresh water on Earth is found in icecaps and glaciers. 30 percent of fresh water is found in ground water leaving around .3 percent of earth’s water as surface fresh water. Of the .3 percent of surface fresh water the great lakes make up 84% of North America 's surface fresh water and about 21% of the world 's supply of surface fresh water.
