Why and how do kites fly? this is a popular question asked by people that don't know much about kites. I will answer that ever so popular question. Kites fly because of weight, drag, wind speed, wind direction and air pressure. When a kite is heavier then air it relies on a rounded surface on the kite that deflects the airflow to create different air pressures. Also, when the wind is moving faster towards the kite the air pressure decreases and creates lift. When the wind is going slow it creates an increased air pressure which decreases lift. Another huge factor of kites flying is drag. Drag is really determined on the design and the set of the bridle line of the kite, and is when gravity pulls down of the kite. One shouldn't have too much drag though, the kite should have more lift then drag to be able to fly well. But, the kite should have drag to gain stability. So basically a perfect kite needs an unbalanced 60:40 ratio of lift to drag. Overall, a kite flys because of weight, drag, wind speed, wind direction, and that ever so important air pressure!

Reservoirs are main water supplies for drinking water, bathing water etc. A reservoir is an amount of water that is held between gaps from rocks in the earth, forming pockets. But, they are very limited because of humans. Humans take way to much advantage of these wonderful springs and eventually we will not have water in them. We use these water resources for drinking, bathing, farming and factories and waste a great deal of it. This isn't the only problem humans are causing, we are causing a great deal of a thing called, water pollution. Water pollution is when humans put waste, chemicals, and other non biodegradable substances into the earths water sources. This is a very bad thing because clouds take water from water sources, and reservoirs are sources of water. Also, The clouds move to other areas, so they take the polluted water and spread it to other masses of water. Basically, although we are only polluting one source we are pretty much polluting every water source their is. Not only that, but the animals drink from the water that we pollute, and get sick and die eventually. The ones that don't die we eat so we are sickening our selves by eating the sick animals. Worst of all, the animals are dying and there will be more endangered and extinct animals,which is really messing up the food chain, one of which humans are a part of. Overall, if humans do not stop polluting the reservoirs we will be killing our selves, and the world as we know it will be destroyed!
