The Story of water

water is all around us ,we have liquid water in rivers and oceans, we have frozen water in ice and glaciers and we have water vapor in clouds and steam water is very important how many oceans are there what is the biggest ocean animal how much water do we use to take a bath what percent of our body is water salt water about 70 of earth is covered with water most of the water is in the oceans there are five oceans the pacific ocean the Atlantic ocean the Indian ocean the southern ocean and the arctic ocean the largest ocean is the pacific ocean it's 156 million square kilometers it's about 15 times bigger than the USA there are also many seas on earth the largest sea is the south china sea it's three million square kilometers one of the smallest seas is the marmara sea it's only about 11 000 square kilometers all the water in the oceans and seas is salt water the dead sea is about 30 salt it's the saltiest sea on earth it's so salty you can float in it fresh water about three percent of the water on earth is fresh water most of this fresh water is frozen it's ice it's in glaciers or polar ice caps some of the fresh water is in lakes and rivers one of the biggest lakes on earth is lake superior in north America it's about 82 000 square kilometers the longest river on earth is the river Nile in Africa it's about 6700 kilometers long some of the fresh water is in the sky it's in the clouds and the rain some of the water is in the soil in rocks or under the ground in caves most of earth is covered with water but only about one percent is fresh water that we can drink the rest is salt water or ice the water cycle do you know where water comes from when it rains water falls from the sky this is called precipitation rain water goes into streams stream water goes into rivers river water goes into seas and oceans when it's sunny the ocean water gets warm some water goes up into the sky this is called evaporation the water in the sky makes clouds then it rains again this is called the water cycle we are lucky to have water in our homes about 1 billion people don't have clean water in their home most of the water we use comes from rivers and reservoirs clean water goes through pipes to our homes water at home we use a lot of water at home we drink water and we cook with water we also use water for washing we use about 80 liters of water when we take a bath we use about 27 liters of water when we take a shower we use water to brush our teeth and we also need water to flush the toilet we use about nine liters of water every time we flush we use water to wash and clean other things too we wash the dishes with water we wash clothes with water we wash and clean everything in the house with water water activities we use a lot of water outside the home we need water for the food we eat meat comes from animals and animals drink water fruits and vegetables also need water to grow we need water to travel we can travel by ship and by boat we can also make power with water hydro electricity is electricity made from water we have fun with water we like to go to the beach in the summer we also like to visit rivers and lakes lots of sports need water sailing surfing swimming water skiing and diving all use water which water sports do you like we need water the human body contains lots of water our body is about 70 percent water our brain is about 85 water and our bones are about 33 percent water water is very important for the human body we can live for four weeks without food but we can't live for more than about three days without water we need to drink about eight glasses of water every day we need to drink even more water when we play sports and when it's hot we need water because it keeps our blood healthy our blood is about 50 percent water blood takes food to different parts of our body it takes oxygen from our lungs to other parts of our body too if we don't drink water our body gets dehydrated if we're dehydrated our kidneys and our brain don't work then we get very sick ocean animals lots of animals live in water some animals live in salt water they live in seas and oceans the biggest ocean animal is the blue whale it can be more than 30 meters long and 200 metric tons it eats very small ocean animals called krill it can eat four metric tons of krill in a day blue whales live in most of the oceans the blue whale is the biggest animal on earth it can be as big as 25 elephants many other animals live in salt water there are sharks and lots of other fish all ocean animals need water water gives them food and oxygen jellyfish are not fish they are invertebrates they don't have a skeleton they need water to support their bodies other animals some animals live in fresh water they live in rivers and lakes fish frogs beavers and ducks live in fresh water big animals also live in fresh water the Nile crocodile lives in rivers and lakes in Africa when large animals come to drink it pulls them under the water and eats them land animals need water too they drink water in the African savannah animals like zebras giraffes and elephants come to the waterhole to drink the savannah can be very hot and dry and these animals cannot live without water hippos need water to keep their skin healthy they stay in water all day to keep cool if they don't have water they get sunburned too much water floods can happen when there is too much rain rivers and lakes become very full floods can also happen when there are very big waves in the ocean where there are floods the water covers roads and paths cars and people can't get out of the area just 60 centimeters of water can make a car float the water goes into houses and people have to leave their homes sometimes they have to get on the roof of their house to wait for help cars and people can't get into the area to help the police and firefighters rescue people with boats and helicopters floods can be very dangerous the water moves fast and it's very strong don't play in flood water save water when there is no water rivers and lakes become dry plants can't grow and animals can't drink if there is no food and no water to drink people die too water is very important we all need to save water you can save water at home turn off the water when you brush your teeth take a shower not a bath you can also save water outside the home collect rain water to water plants don't throw things into rivers or lakes people and animals need clean water not dirty water remember our earth needs water people animals and plants need water save our wonderful water
