WHAT ARE THE EFFECTS OF EXCESS SALINITY ON PLANTS
Salt is a mineral that is found both in solid and liquid form. The liquid is called brine. Salt contains two elements, chlorine and sodium, and is known chemically as sodium chloride. Mineralogists call salt that is found in mines halite. Salt is essential to health. Body cells must have salt in order to live and work. Salt makes up about 0.9 percent of the blood and body cells. It has been estimated that there are more than 14,000 uses for salt. Most people think of salt chiefly as a seasoning for food. But less than five percent of the salt produced in the world each year is used in this way. Meat packers, chemical companies, hide and leather processors, and food processors, such as manufacturers of dairy products use salt and its by-products. Farmers feed salt to livestock and use it as a preservative for hay in storage. Factories, plants, laundries, and other industrial institutions use salt to soften water and condition it. Salt is also used to hold firm the materials used in building secondary roads. It is also used in heat-treating, smelting, and refining metals. There is a little more than ¼ pound of salt in each gallon (or 30 grams in each liter) of seawater. It has been estimated
Gagnard 2 that if all the oceans dried up, they would leave about 4,419,300 cubic miles of rock salt. That would be enough to cover all the United States except Alaska and Gawaii with a layer of salt more than 1½ miles deep. Salt was first taken from the sea by scooping out shallow holes along the seashore. Waves, breaking along the shore, filled the holes with brine. The sun and wind causes the water in the brine to evaporate, leaving behind the crude salt. This process was known as the solar method. The solar method is still used. But, to speed the process of evaporation, the brine is put in enormous iron pans placed over extremely hot fires. Salt obtained in this manner is very pure. But it has been estimated that a single salt plant should contain at least 5,000 acres of land to make the solar system practical. Salt is found beneath the ground in almost every part of the world. Sometimes the salt lies near the surface or even above it. Rocks of salt that appear above the ground are called salt licks.
Running away from your own family and town seems horrible but that’s just what Salva had to do. Salva is a Sudanese child who is stuck in the middle of a war against the Dinka and the Nuer tribe. Salva is the main character in Linda Sue Park’s novel A Long Walk to Water. The book describes the constant struggle of having to live where there is no water, or really bad, not clean, muddy water. The story shows how he ran away into the bush because of a war in his Village. It was not easy to find his family again after Salva ran away. While running from war, he is also separated from his family. Three factors helped Salva survive in a challenging environment, they are Water, his Uncle, and Hope.
I found that there is always unintended events or problems that occur because of salt. For example, if the Egyptians did not depend on salt for mummification, would they still be as obsessed to own a large load of it? Also, if the church had not restricted meat, would the need for salt be forgot instead of advertised to the world? Salt: A World History is very bias based on the fact that the author believes salt is one of the greatest things to happen. Kurlansky repeatedly reminds the reader that without salt, certain wars or cuisines would never come to
(Na+ and CL-) do not react to form a salt until the Water is formed
Water is the most relied upon resource on earth and if it disappeared life could not and would not exist on this planet. So if one of our main sources of water in South Australia, The Murray Darling-Basin, becomes unusable then we would need to find the problem and do everything possible to stop it or counteract it. This report investigates on salinity in the Murray Darling-Basin, using the issue question “Is there enough being done to counteract the effects of salinity in the Murray?” as the focus. Salinity is a key significant environmental challenge which the Murray faces and if left unmanaged it could cause serious implications for water quality, plant growth, biodiversity, land productivity, infrastructure and could lead to a loss of a water source that’s critical to human needs. In this investigation five different aspects of this salinity issue are presented and these aspects include what Salinity is and how it has become an issue, what the effects are, how salinity affects the rest of Australia, what can be done and is anyone doing anything and finally what the visions are for the future of the Murray and its salinity levels.
Sodium Chloride is a compound known commonly as table salt. This compound is used for many things, including food flavoring, a means of preservation and to aid or inhibit a chemical reaction. Saline concentrations have been shown to affect certain enzymes by a process known as denaturing. This process can change the shape of the enzymes active site, possibly minimizing the ability of the substrate to bond to that specific enzyme (Starr and Taggart, 2001).
Theatre as a unique, live art form does not only consist of theatrical performances that tell stories, but are significant as to how they cover certain topics that portray issues within the world. Because of this, theatre is an art form that can be used as a platform to discuss and bring awareness to issues that affect one’s community. The play, In the Red and Brown Water by Tarell Alvin Mccraney follows the upcoming of age story of Oya, a young African-American woman, that struggles to find her true self and identity within the projects of San Pere, Louisiana. With the presence of Yoruban tradition, In the Red and Brown Water explores the themes of poverty and racial injustices among minorities through the distinctive use of design clues,
Common salt is necessary in everyday lives because it carries vital substances. It also has many uses, but is found to be used in food only one percent of the time (McGrath and Travers, 1999). It is used to clear ice and snow off of roads, during the production of chlorine, in livestock feeding, to preserve foods, and to improve the taste of some foods. (Aasen, et Al 1999).
In the novel A Long Walk To Water by Linda Sue Park, Salva has had a hard life. He has no family since he ran away from his school while there was a war. He has been to 2 refugee camps in his life. He meets a man named Michael and he teaches Salva English. He wants to learn English since he’s going to America. Salva is 11 years old, he currently doesn't have a family since there was a war in his village and he had to run away from his school. In A Long Walk To Water, the factors that made survival possible for Salva were speaking fluent English, he ran from danger and he had to beg for food.
The Salton Basin , a below-sea-level depression which extends on the north from Palm Springs , California, to the Gulf of California , in the south. The Salton Sea has undergone historic cycles of filling with water and later drying up. The most recent predecessor to the Sea, that being Lake Cahuilla , last filled this area between 300 to 500 years ago and at one time had a surface elevation above sea level. In 1905 the flooding of the Colorado River was accidentally diverted into the Salton though and thus the Salton Sea was born. When the Colorado River floods retreated in 1907, the surface elevation of the Salton Sea slowly began to drop until the 1930�s when agricultural drainage from the Imperial and Coachella Valleys sustained its level. Soon after , this Sea was turned into a state recreation area, wildlife refuge and a sport fishery. To this day, agricultural drainage and run-off is the major source of water inflow to the Salton Sea.
...lights and rubber, a coolant for nuclear reactors, and is needed to keep the human body under control and running correctly. Sodium was first founded by Sir Humphry Davy in 1807 and is now used for many different reasons in society.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
The global ocean along with seas and bays, accounts for 97% of all the water on Earth, about 321 million cubic miles. Ocean water is salty and is not suitable for drinking or other everyday uses. Only 3% of the water on Earth is fresh (not salty). Over two-thirds of the freshwater is in the form of ice, in glaciers, polar ice caps or permafrost. Another 30% of the freshwater is groundwater. This leaves less than 1% of the freshwater, or 0.007% of the total water on Earth, on the surface in lakes and rivers that are easily accessible.
Nearly every person in the world uses salt or some form of a salt as there are many salts in the world. In America alone we use a lot of salt every day we are one of the top salt using countries in the world. Salt has a part in many things in everyone’s daily lives. Salt has many important things to it such as its crystallization, what salt is and ammonia.
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.
There is a global shortage of drinking water. A person might wonder how this can be if seventy percent of the earth’s surface is covered by water. Most of the Earth’s water is unsuitable for human consuption. Ocean water is salt water, which makes up 97.5% of all water on the planet. Freshwater is only 3.5% of all the water on Earth. Drinking water is sourced from bodies of freshwater.
