Water Polo What is Water Polo? Water polo‚ or Water ball‚ is a team water sport. The playing team consists of six field players and one goalkeeper. The winner of the game is the team that scores the most goals. Game play involves swimming‚ treading water‚ players passing the ball while being defended by opponents‚ and scoring by throwing the ball into a net defended by a goalie. Water polo is very similar to handball on land. Basic Skills Water Polo is a team water activity requiring swimming

Ecology Essay Water makes up 75% of your body and is absolutely necessary for living. But do we know what we are drinking when we drink bottled‚ Recycled‚ and tap water? You might think it really does not matter‚ i mean they are all the same clean water right? Well‚ according to Rebecca Ephriham water that individuals and our families drink could contain deadly toxins‚ and can even cause cancer and other life threatening diseases. Some water is much cleaner than others and a much better choice for

WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called

Water Management Describe Water Management and Use Ground water and surface water make up freshwater sources in the form of streams‚ rivers‚ and wells. Freshwater sources are becoming depleted. We are facing a growing global water shortage due to precipitation‚ runoff patterns‚ droughts‚ and ground water withdrawals. Water conservation is protecting the quantity and quality of the water resources‚ with expectations to reduce the total amount of water being used for various purposes. Water

Introduction Water is one of our most important natural resources. Water is used in different purpose such as domestic‚ industrial supply‚ transportation‚ recreation. However‚ nowadays‚ humans are continuously deteriorating rivers‚ lakes‚ and oceans through different agricultural‚ industrial activities. Abel (1996) states that water pollution defines as “the addition of undesirable materials into aquatic bodies” (p.1). This may cause physical‚ chemical or biological change in water‚ leading to different

India’s historic billionth baby has not led the government to take concrete measures to control this rapid population growth. Jabalpur is located in the heart of Madhya Pradesh and lies 15 kilometres from river Narmada. Its present population is 2 million. Two decades back it was 700‚000.

Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries‚ the water supplied to households‚ commerce and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as

Q1 Q1 A) The sudden closure of valve at the end of a pipeline cause sudden change in the water velocity which in turn creates a phenomenon called water hammer. The water in motion is forced to stop or change direction suddenly (momentum change) and a pressure wave propagates in the pipe. It ’s also called hydraulic shock. The effect of this event can be effectively multiplied many times by the geometry of a piping system if the pressure wave is allowed to reflect‚ or bounce‚ back and forth
