Seawater

forms volcanic mountain ranges known as mid-oceanic ridges. Mid oceanic ridges form in the very deeps of the ocean causing the water temperatures to be very cold. Because of this hydrothermal vents are found in areas where seawater meets hot magma. Hydrothermal vents form when seawater goes down through the cracks in the…

Introduction How can creatures that don’t have eyes, and ears tell if a predator is nearby? We will be looking in depth into the predation of Periwinkles (Littoraria irrorata) and the blue crab (Callinectes sapidus). What are periwinkles? Whats the reaction and relationship between the two species. How can one species detect the other? Once we explore the our creatures we will then conduct an experiment to test if there are any notable difference in the reactions of the periwinkles in the…

Desalination plants take seawater and turn it into freshwater. Many countries are hesitant to use desalination plants because they are extremely costly, but California has previously opened one and they know what needs to be done. Renewable energy might be more expensive than current…

cost species that can be maintained in a laboratory environment, have external fertilization and have distinct stages for viewing development in offspring. They are external breeders, so when the gametes are mature, they are released into seawater. The seawater carries the gametes where they will fertilize and develop. How does the sperm find the eggs? The jelly coating on the mature eggs produce a chemical signal that attracts sperm (Gilbert, 2000). This method of sperm finding egg must…

as the Mid-Atlantic Ridge and the Galápagos Rift. Seawater seeping deep into the Earth’s crust through fissures and cracks in the seafloor is heated by magma beneath the surface, causing the water to boil and rise back up to the surface. As it rises, the water dissolves and…

km (93 to 124 miles) below continents”. These scientists aren’t saying that diamonds form solely and directly from seawater, they are saying that fluids from the oceanic crust may have reacted with continental rocks and created the right environment at which diamonds could form. In conclusion, even though the question that all diamonds form using seawater is still up in the air, we are constantly learning more about diamond formation. According to Weiss,”If a direct…

categories, military experiments, pharmaceutical and racially motivated. The military experiments were primarily conducted at Dachau and were meant to find ways to better the German army. They included the hypothermia/freezing experiments, the potable seawater experiments on gypsies, finding cures for war wounds and the high altitude tests. The pharmaceutical experiments were conducted to find cures for various illnesses such as malaria and tuberculosis. This category also includes the phosgene…

roughly in the 1930’s when the agriculture systems in place accounted for 90% of California’s economy. This causing a systematic drying up of water basins almost depleting them by the 1960’s, the over pumping of the basin, caused contamination from seawater intrusion as well. It was around this time, in the 1960’s that the talks of developing and utilizing a system to collect and reuse of wastewater began in Orange County. Unfortunately these talks were was immediately dismissed as being what…

023 J g−1 K−1 (0.249 cal/ g × °C). Its most common oxidation number is +2. Pure magnesium is highly active chemically and, therefore, does not occur free in nature, but its mineral compounds are widely distributed in most countries of the world. Seawater, which contains about 0.13% magnesium, is a virtually inexhaustible source. One cubic mile of ocean contains about 6 million tons of magnesium. The metal is high in the electromotive series, which allows the metal to displace a large number of…

An additional large factor in the increasing levels of seawater is the fact that ice caps in the arctic are melting. Unfortunately, the melting ice caps are another result of solar warming. Over many years, “the vast ice cover around the North Pole has shrunk due to global warming. This has led to rise in sea levels, which ultimately affects coastal regions” (“Melting Ice Caps Affect Coastal Regions”). In this article, the author goes into depth on the results of the melting ice caps. Another…
