Recommended: Similarities between saltwater and freshwater

H_2 O (freshwater) is a well-known substance present in all organisms and all biomes on earth in various forms. Water is a substance which has a unique molecular structure that allows it to appear in different forms on earth and even in outer space. When water is in its simplest form, it appears as a liquid substance at room temperature. This discussion will address the similarities and differences between freshwater and saltwater. Although it is chemically very similar, most land organisms rely on freshwater to survive but only a mere 3% of the earth’s water is fresh.
Saltwater and freshwater have a few similarities as well as differences. These two types of water both have the same molecular structure, but saltwater just contains dissolved salts and therefore can exist in three different states which is a liquid, gas or solid state and this phenomena can occur depending on the atmospheric pressure (Coleman, 2013:1). The difference between saltwater and freshwater is that saltwater consists of 96.5% of water and 2.5% of dissolved salt. There are some saltwater masses which are less ...

  • The Saltwater Frontier Summary

    189 Words  | 1 Pages

    On Wednesday, February 15th, I was able to have the opportunity to listen to Andrew Lipman. Andrew Lipman is the author of The Saltwater Frontier: Indians and the Contest for the American Coast. In the novel, he explained the life of Native Americans living in New England and on the coast of Long Island. During this time, most individuals relied on trading natural resources. In order for profit for the resources, the colonists and Native Americans used wampum. Wampum was used as a sacred gift in Native American culture as a peace offering, funerals and marriages. Colonialists had an advantage towards using wampum. They used beads as a commodity for furs. Native Americans relied on canoes for transportation. Canoes can hold up to fifty people.

  • Pros And Cons Of Drinking Salt Water

    439 Words  | 1 Pages

    In my opinion, I think salt water is bad for you. If you’re stranded in a deserted island and you drink salt water, it’ll just make you even more dehydrated and probably kill you faster. If there’s nothing to drink at the island, then don’t drink the salt water because that’ll just make you die faster. Your body also won’t be able to get rid of all the extra salt. Your body fails when it tries to get rid of too much salt. Your kidneys produce urine to get rid of all that salt but it needs fresh water to actually make it work. If you drink salt water, then too much salt will go into your body and it won’t make the kidneys work which will eventually make your body fail. Salt water will pretty much make your body stop functioning if you drink too much salt water. Some salt is good for you but drinking a lot of salt water can make your body go weird or different. Our blood can’t really handle too much salt. When there’s a lot of salt, the water in the cell goes outside to balance itself. Since you’re drinking salt water, there’s a lot of salt which causes a lot of water to go outside to help out. That can cause the cells to actually shrink and that’s obviously not good. If the cells shrink, then they can’t carry out

  • Haemolysis Vs Salt Water Difference

    686 Words  | 2 Pages

    Drowning in salt water and fresh water is different, even though you would think it would be the same. Only around 10% of people who drown will drown in salt water, the other 90% drown in fresh water; more specifically, they drown in swimming pools. A person drowning in salt water can be dead from anywhere between five and thirty minutes, while in fresh water it can take anywhere between five and twenty minutes. That’s a ten-minute difference and it’s a big difference. So, why does it happen like this? Why can a person be more likely to drown in fresh water, which is generally more controlled than salt water? Why is there a ten-minute drowning difference? It all has to do with osmosis, both of the solutions react different with our bodies.

    Most ocean water has about 7 teaspoons of salt in 1 liter of water (sciencelearn.org.nz). The higher the concentration of salt the lower the freezing point of water. The freezing point of a substance is the temperature at which a substance usually liquid, becomes a solid. Water has a known freezing point of zero degrees Celsius.

  • Comparing Freshwater vs. Saltwater Fishing

    1303 Words  | 3 Pages

    My friend had invited me along with him and his family to the ocean. It was vacation for the family, but for him and me it was the beginning of a week of serious business. We had an obsessive hobby to pursue. As avid and long-term freshwater fisherman, we were thrilled by the thought of catching those large and exotic saltwater fish we had seen on television a billion times before. Yet little did we expect there to be such vast differences between our freshwater fishing and the saltwater fishing, which we were about to pursue. We learned through trial and much error that in order to have a successful saltwater fishing experience we had to make adjustments to all the freshwater tackle, tactics, and gear we knew.

    The Biological Importance of Water Water is vital to all living organisms, as a constituent of cells, a reactant in metabolic reactions, and a solvent for aquatic organisms. Without water life on earth would not exist. Water also provides an environment for organisms to live in. Water consists of two hydrogen atoms and one oxygen atom forming H2O. The two hydrogen’s and the oxygen bond together through covalent bonding, which is the sharing of electrons.

    Ocean water is often referred to as salt water. Ocean water becomes salty as water flows in rivers, it picks up small amount of mineral salts form rocks and soil of the riverbeds. This very-slightly salty water flows into the oceans. The water in the oceans only leaves by evaporating, but the salt remains dissolved in the ocean, it does not evaporate. So the remaining water gets saltier and saltier as time goes on.

    Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
