"The Great Salt Lake is a hallow body of saltwater in Northwestern Utah. It is the largest salt lake in North America. It is the remnant of Lake Bonneville that once covered the Great Basin that was 1,000 feet deep.\n...\nThe last Ice Age around 15,000 years ago Lake Bonneville formed. It was an ancient lake the size of Michigan. The size of the lake covered 1/3 of present day Utah and parts of the neighboring states. As the lake receded the amount of evaporation was higher than the inflow. The sea levels are marked by former beachlines on the mountains and by rich soil deposits on the terraces on the east. When the evaporation was not as high it left behind bathtub rings on the mountains indicating the sea level. As evaporation continued the lake decreased in size. As the evaporation continued the lake has become saltier."

“Between 2000 and 2003, Salt Lake City saw a net loss of some 1,873 people, with the city's population declining to an estimated 179,894 residents, according to a U.S. Census Bureau report released (today).” \n\nIn July 2005 the population figures were as follows:\nSalt Lake City Metro: 181,743 and Salt Lake Area: 1.2 million\n\nSee the references below:

As water flows down rivers into the ocean, minerals dissolve in it. When the water gets to the ocean, solar radiation vaporizes the water and leaves the dissolved minerals behind. Over time, millions and millions of years, the concentration of these minerals increases.  The Salton Sea in California is an example of a speeded up version of the process. About the year 1909, the Colorado River was diverted from its course and flowed into the Salton Sea, which was a dry low area. It took some time to block the diversion. By the time it was complete there was a new fresh water lake there.  During the last 90+ years, that fresh water lake has turned into a sea more saline than the ocean.

Because the water collects minerals from the floor of the ocean and so on and it isn't circulated or "refreshed" as a freshwater lake would be.  For instance, the Great Lakes are freshwater because they constantly drain out into the oceans.  The water is replenished all the time, not just sitting in one spot.  It doesn't give them time to collect the minerals to get salty.  If a lake, such as the Great Salt Lake in Utah, doesn't have this circulation (not sure what the scientific word is for it, but there is one), a place to drain so the water can be replenished, it becomes salty because it absorbs the minerals.

If you mean the Noah flood, there is some evidence for a great flood of water empting into the Mediteranian and close enough for it to be historical to the people writing the Bible. The outlet from the Black Sea(?) was blocked and suddenly opened flooding the town below.\nthere is a great flood plain where water froze formed a lake for many years and then broke loose spilling into Western Idaho and Eastern Washington St. Oregon. It looks like a barren lake bed today. The deposits indicate this happened many many times.

The western quarter of Utah is very desolate with few towns or paved roads - beyond I-15 at the foot of the central mountains the land becomes mostly flat interrupted only by occasional ranges of hills, part of the Great Basin Desert that stretches across Nevada. At the edge of this forgotten region lies the largest expanse of sand dunes in the state, contained within the Little Sahara Recreation Area (120 square miles), a BLM-managed location popular for camping, hiking, exploring and photography but which is mainly known as a centre for off road vehicle use. \n\n\n\nLocation: The nearest main road is US 6 from Provo to US 93 in Nevada - one of only four paved routes that cross the state border. This skirts the edge of the Sevier Desert, part of a huge empty area of mud flats and salt plains which also includes the Great Salt Lake Desert; all this area was once under the waters of ancient Lake Bonneville. The entrance road to the Recreation Area leaves US 6 near Jericho, a lonely stop on the Union Pacific railway between Salt Lake City and Las Vegas. After a few miles it passes a visitor centre (usually closed) and the entrance station (the entry fee is a rather steep $6) and leads into the centre of the dunes; the vegetation becomes more and more sparse and the road finally ends, White Sands National Monument style, in a large flat area of compressed sand with dunes all around. \n\nSand Mountain: Little Sahara seems quite popular; many visitors bring large RVs with dune buggies or other off road vehicles in tow and stay for some time. There are four official campsites and dispersed camping is allowed anywhere away from the road. The most impressive location is Sand Mountain - an elongated ridge, highest point of which is almost 700 feet above the dunes with steep, smooth slopes of sand devoid of any plants; these represent the biggest challenge for the ORV crowd. The mountain can also be climbed on foot. This is difficult but rather fun, especially when sliding back down - the ascent takes half an hour but only a few minutes are needed to return. Some parts of the hillside have outcrops of weathered, bluish grey sandstone which help when scrambling up, and the ridge on top is formed by the same rock. From here there are great views over vast areas of undulating sand, stretching away to the southwest, a view only slightly spoiled by a power station a few miles away. The top is usually very windy with much airborne sand blown by the prevailing southerly winds - not a good place for expensive camera equipment. \n\nOther Areas: Most of the northwest corner of Little Sahara is off limits to all vehicles to provide a sheltered habitat for desert plants and wildlife, which includes mule deer, pronghorn antelope, snakes and birds of prey. This is designated the Rockwell Natural Area, and is a good place for backpacking trips. The highest peak in the main recreation area is 5,828 foot Black Mountain, another popular ORV location with many trails criss-crossing the grassy slopes\nhttp://www.americansouthwest.net/utah/little_sahara/recreation_area.html

Magnesium reacts with water to produce hydrogen.  It's salts are water soluble.

Copper ore is extracted from the Earth usually in rocks dug from strip mines. Kennecot copper in Utah has this humongous open pit near the Great Salt Lake that looks like a mountain dug into the Land. The ore rock is crushed and then run through a blast furnace (Smelter) at extremely high heat (Thousands of degrees fereinheit) which melts out the different metals in the rock including the copper. Then each metal is extracted from that mix and we have pure copper.

Scientific theories behind the origins of sea salt started with Sir Edmond Halley in 1715, who proposed that salt and other minerals were carried into the sea by rivers, having been leached out of the ground by rainfall runoff. Upon reaching the ocean, these salts would be retained and concentrated as the process of evaporation (see Hydrologic cycle) removed the water. Halley noted that of the small number of lakes in the world without ocean outlets (such as the Dead Sea and the Caspian Sea, see endorheic basin), most have high salt content. Halley termed this process "continental weathering".

There are a couple ways. Hot spots can build up islands through volcanic activity, like Hawaii. Some islands can be created by subduction volcanism (Japan). Other islands can be uplifted at convergent or possibly transverse plate boundaries.\n\nIslands can also be created by erosion and inundation, as in a case of sea level rise where the water covers low lying areas while higher areas get "separated" from the land by water (St. Lawrence Island in Alaska). Glaciers can scour channels around large land masses, then recede and the channels can become filled with water to surround the land masses and make them islands. Manhattan Island was actually created by a continental glacier pushing a bunch of sediment out into the ocean and then receeding (it is a moraine).\n\nSome islands can be created purely by sediment deposition, such as those at the mouths of deltas.

Uh, there is the Dead Sea. But I think it is drying up.\nYou can try Salt Lake, in Utah US.\n\nThese are saltwater lakes with high concentrations of salt.

Salt comes from  dissolved rock. Rivers carry that salt from the land to the ocean. It's that simple.

Lake Peigneur is a 1,300 feet (396 meters) deep, salt-water lake near New Iberia, Louisiana. The name Peigneur is French for "comber".\n\nThe lake was previously an eleven foot shallow fresh-water lake until an unusual man-made incident on November 21, 1980. At that time, Diamond Crystal Salt Company operated the Jefferson Island salt mine under the lake while a Texaco oil rig was drilling down from the surface of the lake.\n\nAll the evidence having been destroyed in the ensuing maelstrom, the generally accepted cause of the disaster is that a miscalculation from the Texaco drilling operation as to its location, relative to Diamond Crystal's, ended up with the drill puncturing the roof of the third level of Diamond Crystal's salt mine, creating an opening in the bottom of the lake (similar to one removing the drain plug from a bathtub). The lake then proceeded to drain into the hole, with the packed salt underneath absorbing water nearly as fast as it poured in, resulting in the draining of the lake into the salt mine. A resultant whirlpool sucked in the drilling platform, eleven barges, many trees and some of the surrounding terrain. The salt mine was so large and so able to absorb the water pouring into it that the water level dropped significantly, enough to reverse the flow of the Delcambre canal that leads to the Gulf of Mexico. This backflow created, for a few days, the tallest waterfall ever in the state of Louisiana, at 150 feet (50 m), as the lake refilled with salt water to replace the fresh water now in the salt mine.\n\nFortunately, even with the grand physical effects there were no injuries and no human lives were lost - all 55 miners in the salt mine were able to escape, and the drillers escaped the platform before it was sucked into the lake - though three dogs were killed. Later, in the aftermath of the disaster, nine of the eleven sunken barges popped out of the whirlpool and refloated on the lake's surface.\n\nThe event dramatically affected the ecosystem of the lake (both by greatly increasing the depth of the lake from eleven feet to 1,300 feet, and changing the lake from freshwater to saltwater) and the biology (by introducing new plants and changing the type of fish that inhabited the lake).\n\nThe drilling company, Texaco and Wilson Brothers paid $32 million (USD) to Diamond Crystal and $12.8 million to nearby Live Oak Gardens in out-of-court settlements to compensate for the damage caused.

ok first of all just because one thing the bible says is true,that wouldnt make the entire thing true and second of all,originally the Earth was a ball of molten rock that cooled down.water didnt come around till later(im not sure how though)

Mt. St. Helens was formed from the subduction of the Juan de Fuca Plate underneath the North American Plate.  Subsequent eruptions, producing basalt and andesitic lava flows, have either reshaped or built up the volcano over time.

Most people would think that experts agree on an explanation for the formation of such a grandiose site as the Grand Canyon. Surprisingly that isn't so. It is an enigma. The latest attempt to figure it out occurred as late as June last year at the Grand Canyon Symposium 2000. The Colorado River is held generally responsible for carving the Canyon. However, even before the Glen Canyon dam stemmed its awesome desert floods, the river seems hopelessly inadequate to have formed such a geological spectacle. The Colorado River flows west from the Rockies and encounters a raised plateau known as the Kaibab Upwarp. Instead of turning away from that barrier it continues through the plateau. How could it do that? The river is much younger than the Kaibab Upwarp so it could not have progressively cut the Canyon even if the land rose very slowly. In any case, most of the material that was removed from the Canyon seems to be missing, according to a report from the symposium, leaving little evidential support for the original theory that a simple progression of water erosion formed the Canyon we see today. Since the 1930's and 1940's, geologists have searched for other explanations -- that the Canyon once drained to the south-east (reversing the route of the present-day Little Colorado, then joining the Rio Grande and into the Gulf of Mexico. When problems arose with that explanation too, it was proposed that it once flowed NE along one of the present-day side tributaries such as Cataract Creek.
