• The chemical formula of water is H2O, it is made up of oxygen and hydrogen
• For existence of life on earth water is very essential
• Each molecule of water is a blend of 2 hydrogen and 1 oxygen atom
• Water is present in liquid, gas and solid state
• Water is usually referred to as in liquid state, the ice is the form of solid state and steam and water vapor is in gas state
• Around 70% of the earth’s surface is covered by water
• The Pacific ocean, the Atlantic ocean and the Indian ocean are the 3 largest oceans on the earth
• The Marina Trench found in the Pacific ocean is the deepest known point in the world’s ocean
• The rotation of the earth and the gravitational pull of moon and sun acting on ocean water cause ocean tides
• Every Kg (2.2lb) of seawater contains (1.2oz) 35 grams of dissolved salt, water from a ocean or sea is called seawater.
• As the amount of salt dissolved in water increases the freezing point of water reduces. Sea water freezes at 2 °C (28.4 °F) with the average level of salt in it.
• Nile River is the longest river in the world, it reaches 6650 kms in length ( 4132 miles)
• Amazon River is the 2nd largest river in the world, reaching 6400 kms in length (4000 miles)
• Water is a good solvent, with sugar, acids and salt easily dissolving in it. However oil and fats don’t mix well in water
• Missouri River is the longest river in the USA, it is slightly longer than Mississippi River (2,320 miles), at around 3,770 km (2,340 miles) in length. The 2 rivers combined together form the longest river system in North America
• The water cycle includes water evaporation, cooling, rising to sky and condensing into tiny drops of ice crystals or water that we see as clouds, before evaporating again it falls back on earth as snow, rain or hail.
• Scientists suggested possibility of liquid/water on the red planet. Water at the polar ice caps of Mars planet is in the form of ice.

• Pure water has no odour, no taste, the pH level is around 7 I pure water
• At normal conditions of sea level water boils at 100 degree C (212 degree F). according to barometric pressure the boiling point of water changes relatively. For ex- water boils at 68 degree C (154 degree F) on Mount everest, at the same time water in deep ocean near geothermal emit remain in liquid form at 100 degree C (212 degree F)
• In freezing conditions water bursts pipes as it has turned into ice. Water expands as it cools from 4 degree to 0 degree C.
• Water against gravitation force can move up narrow tubes known as capillary action.
• People around the world have access to clean and pure drinking water, but poorer areas are facing difficulty. Here water pollution is at high level and it is dangerous to the people’s health with deadly bacteria, viruses like E coli and Cryptosporidium
• Agriculture needs water for irrigation, to yield good crops water is added to sil
• Water is essential to drive dehydration, depending on the temperature you might require certain amount of water.
• To extinguish fire firefighters need water, Helicopters drop huge gush of water to stop fire to control further damage
• Delivering clean water to villages, homes in various cities and countries is taken care by the water industry. Other services include sewage treatment, purification, distillation, filtering and plumbing.
• Hydropower is created by water, this power is created by using water to drive water to turbines connected to huge generators. There are many hydroelectric stations around the world
• For cooking water is very essential, boiling and steaming of food requires water.
• Water is also used for water sports activities. Swimming, surfing, water skiing all need water, other forms of water ice and snow are used for ice skating, ice hockey, snowboarding, skiing etc.
