In Antarctica there are massive amounts of frozen water that are locked up in ice. Some of Antarctica’s ice sheets are more than 2 miles thick‚ and if the ice starts to melt then sea levels will rise dramatically. Sadly the ice has started melting already. There are radars that are measuring the amount of water that there is now‚ but scientists are trying to figure out how much water will be if all the ice will melt. Antarctica contains more than 90% of the worlds ice‚ together with Greenland‚ it’s

Dams can cause excess erosion on downstream of a dam due to the lack of sediments in the water. The sediments instead come from the bed and banks. Break walls can also affect the sediment levels as well as the flow of the water causing a change in the water based on the side of the break wall. An example of this could be the dam in Marquette‚ which upon inspection down the dam‚ you can see the distinguished erosion lines on the riverbanks

“Another Impossible Huge Dam Built‚” pokes fun at the Grand Coulee Dam‚ which at the time was the largest man-made structure in the world’s history.

The Onion takes a sarcastic and humorous spin with what actually happened‚ the amount of giant dams built. The Grand Coulee
