all of North America in over 6‚000 feet of snow and ice. During this time‚ the temperatures went up and down causing the glaciers to melt or to expand‚ often times causing them to move. This carved the landscape of Michigan (Why). Glacial erosion can happen in two primary ways‚ the first is called plucking‚ and this happens when rocks and debris stick to the underside of a glacier and then are carried off with it. The second is called abrasion‚ this is more of what we might think on when we think of

living organisms. It is a chemical compound whose formula is H2O. It covers 71% of the earth’s surface and is necessary for every known organism to live. 97% of the total water found on the earth lies in the oceans. The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%). Water is neutral to litmus. Its freezing point is 00C and melting point is 1000C. It is also regarded as “Universal solvent”. The importance of water is undeniable

The hypothesis that was created as to what process formed the parallel groves was‚ The Glacier Theory. What occurred in this process was that‚ 15 thousand years ago‚ the whole section was covered with flowing ice that had huge boulders underneath it. When the ice dragged the boulders over the bedrock that was pressing against it‚ the smaller

A U valley always starts as a typical V shaped valley however through the shape of the glacier‚ it uniformly turns the landscape into a U shape. A Glaciated Valley forms when a glacier travels down a slope. A glacier is a slow moving mass of ice that is formed by the accumulated and compacted snow on the mountains. When this glacier travels down the

Then he talks about the different theories of how this happened. He concludes with speaking of the future and the climate it possesses. Scientists have discovered that in the past million years‚ glaciers have covered the Earth’s surface on several different occasions. There have been several "ice ages" in the Earth’s past‚ and twenty

The glaciers that covered Michigan over one million years ago scraped the top layer of the landscape as they moved‚ carving landscapes throughout the land. As the glaciers melted‚ rivers streamed through the channels created by the glacier. The streams that formed from the glaciers spread the materials caught in the glacier throughout the land down south. The glaciers aimed to travel the least resistant path and thus the

Ice is also what forms glaciers‚ and this features prominently in another one of Eliasson’s works The Glacier Series. These massive formations not only form slowly but also move slowly‚ much slower than the human eye can perceive‚ much less the attention span wishes to
