    rock are removed from the Earth’s surface by natural processes such as wind or water flow‚ and then transported and deposited in other locations. While erosion is a natural process‚ human activities have dramatically increased (by 10-40 times) the rate at which erosion is occurring globally. Excessive erosion causes problems such as desertification‚ decreases in agricultural productivity due to land degradation‚ sedimentation of waterways‚ and ecological collapse due to loss of the nutrient rich

They can be fatal depending on how bad the injury is especially if it is to the brain. Folic acid works with vitamin B12 in the formation of red blood cells. Deficiency in both folic acid and vitamin B12 causes a certain type of anemia known as macrocytic anemia. Macrocytic anemia is a type of anemia that

    Determination of Calcium ions in milk using titration. Background Calcium is a mineral which is essential to the human body. In fact 1.5% of the human body is made up of calcium‚ and not just the obvious uses such as bone and teeth formation but it is also a vital factor in many enzyme reactions‚ for example blood clotting. It also partakes in the regulation of the hearts rhythm. Lack of the crucial mineral can result in the build up of cadmium and lead‚ both of which are toxic. along

    Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

    Affecting Rates of Chemical Reactions Prepared By: Kelly Gunter For: Ms. Brohman Course: SCH-4U Introduction The main purpose of this lab was to investigate how temperature‚ concentration‚ the addition of catalysts‚ and the substitution of a more reactive reactant‚ can affect the reaction. The collision theory explains that in order for a reaction to occur‚ reacting particles must collide with one another. An effective collision makes reactants result in a reaction and for to
