Okay, so today in Physics, we were talking about density. My teacher said something about getting in a bathtub and seeing the water level change due to the mass (more specifically, surface area of that mass); and this got me thinking... Alright, so a big topic in todays time is Global Warming (which I believe is just a massive hoax; no offense to all you Al Gore worshipers out there); the theory that there is a gradual increase in the overall temperature of the earths atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Im sure you all know it well. Anyways, one of the recently big problems discovered by scientists about global warming, is that we are causing the polar ice caps to melt (Ive read in several articles, that theyre actually the largest theyve been in 30 years or so), and thereby increasing water levels on the planet (almost all bodies of water are connected; whether rivers, streams, the ocean, and seas; water level affects them all equally). So anyways, as my teacher said this thing about water level changing as one gets in the bathtub, I thought, Well, the same thing could be happening in the ocean; as well as all other connected bodies of water. Think about it. Think about all the mass (increasing surface area) weve put into the water throughout the approximate 6,000-8,000 years weve been on earth; all the millions of ships (sunken or floating), all the structures underwater (bridge posts included), barges, house-boats, oil rigs, all the debris, junk, and other miscellaneous stuff in the oceans, rivers,and lakes; all the flood debris washed into the water and never found; think of the polar ice caps and how much they increase that surface area as well. All this added surface area disperses large amounts of water equally across all connected bodies of water, which thereby increases water level slightly (because, hypothetically, while the surface area changes, the volume of all that connected water never changes). And since the volume of these connected bodies of water is so extremely massive, the large dispersion created by all increased surface area is actually fairly smaller than it seems it would be; but large enough for us to take notice. So, thats my theory on why water levels are rising. Besides, even if the ice caps were completely melted away, the water dispersed wouldnt be enough to raise water levels, because ice expands as it freezes; which means that if you stuck all that ice in a massive cup (and it filled the cup entirely) and melted it, it would never fill the cup completely. Water levels would actually be lower due to the lack of surface area created by the ice (which would fill a larger area than water would). Area created by ice > Area created by that melted ice
