channels supplying water from the ocean slowly closed‚ and the sea began to dry up. The water evaporated more rapidly than it was replaced. Salts and gypsum were precipitated and filled the basin‚ in time the basin was no more - the landscape was a nearly flat surface‚ with little relief. As eons passed‚ the old sea basin‚ the reef‚ and the surrounding regions were deeply buried under additional thousands of feet of sediments. Starting with its burial and continuing as movement began to occur in more recent

Topographical classification Rivers can generally be classified as either alluvial‚ bedrock‚ or some mix of the two. Alluvial rivers have channels and floodplains that are self-formed in unconsolidated or weakly consolidated sediments. They erode their banks and deposit material on bars and their floodplains. Bedrock rivers form when the river down cuts through the modern sediments and into the underlying bedrock. This occurs in regions that have experienced some kind of uplift (thereby steepening

tremendously high cost of fixing a polluted mine‚ and a very‚ very bad track record. The Polymet mine will cause so much pollution such as the sulfuric acid drainage: sulfide + H20 + O2. If this is to be leaked into the rivers it can cause toxicity to marine life. The Polymet Mine my also cause pit walls‚ waste rocks piles‚ tailings basin‚ and even heavy metal contaminants which will cause a lot of damage to marine life and life on land. The second point is that Polymet has a very bad track record

All ecosystems have the ability to withstand stress. They are able to resist being disturbed or altered and will restore themselves to their original condition if not disturbed too drastically. There are both natural and human induced stresses. An ecosystem is the dynamic complex interaction of plant‚ animal and microorganism communities and their non-living environment as a functional unit. Ecosystems include the biotic (living) and abiotic (non-living) elements of the environment and the relationships
