Michigan, with 2,232 miles of shoreline. If you include islands, it's 3,288 miles.

Yes, I've already been twice this season. Six of our 12 ski resorts have already opened in the past month. The other 6 are opening this week.

The four states are Michigan, Wisconsin, Illinois, and Indiana.  Lake Michigan is the only Great Lake contained entirely within the United States; it's the only one that does not border Canada.\n\nAnother interesting thing about Lake Michigan is that back during the time of the Northwest Territory (which eventually became Ohio, Indiana, Michigan, Illinois, and Minnesota), the politicians said the Michigan Territory was supposed to run eastward from the south end of Lake Michigan over to Lake Erie.\n\nIf that had held, Toledo would've been part of Michigan, and Indiana would have barely touched the lake.  Anyway, the Ohio and Indiana politicians were more powerful in Washington, so the Indiana border was moved ten or twenty miles north (giving it a real lakefront), and Toledo went to Ohio in exchange for what's now Michigan's Upper Peninsula (which otherwise would've been part of Wisconsin).\n\nI guess Ohio, Indiana, and Michigan all came out ahead, with Wisconsin being the sole loser in all this.

The coldest tempeture recorded in Michigan was on\nJan. 19th, 1994\n\nAmasa, Michigan......53-F\n\nThats below zero.\n\nThought we were the only ones who get cold weather eh??

Don't know for sure, but at the rate global warming is going we're all going to find out!\n\nScientists have speculated that there are life-forms that have not been in contact with the surface  for 15 million years on the bottom of Lake Vostok. The Earth's heat and the pressure/insulation of miles of ice above it keep the Lake Ontario sized body of water from freezing, like the oceans on Europa. No one really knows what is down there because drilling down with current technology would contaminate the lake with surface microbes and change whatever ecology is down there before people can study it.\n\nhttp://www.bbc.co.uk/science/horizon/2000/vostok.shtml\n\nMy guess is just a whole lot of very durable microbes, although some truly strange higher life could be down there if there are hydrothermal vents that would make regular vents seem normal.

Not very long. In most circumstance 5-7 minutes. However, in some cases, let's say, when someone falls into a half frozen pond or something, the cold is suppose to slow down their body system enough that there have been a few cases where people have been pulled out of FREEZING water 20 minutes later and they lived. Some may have had brain damage but they lived. I hope this helps!

CB provides a great chart. Clearly, though, the high number for Michigan (and Wisconsin, for that matter) is due to the portion of the bordering Great Lakes which officially fall within the state's borders. The Great Lakes, for the most part, are split down the middle and divided between bordering states and provinces. If you remove this factor, Florida would be at the top of your list.

If you mean to say the Winter Olympics it is 4 times, first in Lake Placid, New York in 1932, then in Squaw Valley, California, 1960, next it was again in Lake Placid, New York in 1980 and finally in Salt Lake City, Utah in 2002. If you mean to say the Summer Olympics it is 4 times also, first in St. Louis, Missouri, in 1904 which was Olympic number 3, then in L.A, California in 1932 which was the tenth Olympic, next it was in L.A, California too in 1984 which was the 23rd Olympic and finally it was in Atlanta, Georgia in 1996 which was 26th Olympic.

2 times only...........

Yes, and Lake Michigan even qualifies as an "inland sea" because of its size.  Impress your teachers with that :)

This is kind of like asking how many mountains are there, and then realizing you don't know how to distinguish a mountain from a mole hill. Until you can define how large a body of water makes a lake (are ponds lakes?), there is no definite answer. \n\nMinnesota is known as the land of 10,000 lakes, and yet some estimates put it at 15,000 lakes.  Here's a lake index for Minnesota: http://www.rook.org/earl/bwca/lakes/#Index\n\nIn order to ge a first order approximation for you, I ran a search on the USGS Place Names index and got an error message that the server was down. . They don't have it completed, so several states are still missing.  You might try a search on this place names index. using "lake" as your feature class , I also tried a search using Google Earth, and got only a handful of features. Obviously Google Earth is still being built.

482 times to be exact

I think it was over before it even got started.  There were a few caught a few weeks ago, as of late, nothing.  I have heard that they are running late down state (port huron), so don't give up hope yet.

3 times so far. 1954 (in Switzerland), 1974 (in Germany, then West Germany) and 1990 (in Italy)

During winter the water at the surface of lake or pond gets cooled.\n\nDue to cooling density of water increases; denser water\ngoes down, while the relatively hot water comes up. This is convection.\n\nBut water has a peculiar property that below 4 degree C it becomes less dense.\n\nTherefore when the surface temperature is 4degree and below, the water at the surface cannot go down. Hence convection of water is stopped. \n\nThe temperature increases relative to water surface.  If the temperature of the water surface reaches freezing temperature, ice is formed on the surface and the freezing takes place from top to bottom.\n\nThus lives of water living creatures are saved from freezing.

Ice ages are cyclic.  About every 40,000 nyrs.\n\nThe next one is in about 10,000.
