Water is composed of two elements, hydrogen and oxygen. Its chemical formula is H2O … This is a fact that everyone knows. But here we will show you 40 facts on the water !!! After reading, I hope you think about our water consumption. It is very important that we share these facts so that everyone is more responsible.
1 – Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs;
2 – Water regulates the Earth’s temperature, mainly by the oceans;
3 – It also regulates the temperature of the human body, carries nutrients and oxygen to cells, cushions joints, protects organs and tissues, and removes wastes;
4 – 75% of the human brain is water. The human body of an adult has up to 65% water in its composition. In a newborn the number is even higher: 78%;
5 – Almost 800 million people lack access to clean safe water every day;
6 – Water covers around 70% of the Earth’s surface;
7 – There is more water in the atmosphere than in all the rivers of the world together;
8 – In Latin America there are 36 million people without access to good quality water;
9 – A person can live about a month without food, but only about a week without water;
10 – Water is part of a deeply interconnected system. What we pour on the ground ends up in our water, and what we spew into the sky ends up in our water;
11 – On average, an American resident uses about 100 gallons of water per day. A European resident uses about 50 gallons of water per day. On average, a resident of sub-Saharan Africa uses 2 to 5 gallons of water per day;
12 – A swimming pool naturally loses about 1,000 gallons (3,785 liters) a month to evaporation;
13 – Water from a sea or ocean is known as seawater. On average, every kilogram (2.2lb) of seawater contains around 35 grams (1.2 oz) of dissolved salt;
14 – The freezing point of water lowers as the amount of salt dissolved in at increases. With average levels of salt, seawater freezes at -2 °C (28.4 °F);
15 – The longest river in the world is the Nile River, it reaches 6650 kilometers in length (4132 miles). The second longest river in the world is the Amazon River, it reaches 6400 kilometres (4000 miles) in length;
16 – The longest river in the USA is the Missouri River. At around 2,340 miles (3,770 km) in length it is slightly longer than the Mississippi River (2,320 miles). The two combine to form the longest river system in North America;
17 – The average cost for water supplied to a home in the U.S. is about $2.00 for 1,000 gallons, which equals about 5 gallons for a penny;
18 – Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water;
19 – Water makes a good solvent with many sugar, salts and acids easily dissolving in it. On the other hand oils and fats don’t mix well with water;
20 – The water cycle involves water evaporating (turning into a gas), rising to the sky, cooling and condensing into tiny drops of water or ice crystals that we see as clouds, falling back to Earth as rain, snow or hail before evaporating again and continuing the cycle. Learn more about the water cycle;
21 – Water in the form of ice is found at the polar ice caps of the planet Mars, some scientists have also suggested the possibility of liquid water on the red planet.
Pure water has no smell and no taste, it also has a pH level around 7;
22 – While most people know that water boils at 100 °C (212 °F), this is at the normal conditions of sea level. The boiling point of water actually changes relative to the barometric pressure. For example, water boils at just 68 °C (154 °F) on the top of Mount Everest while water deep in the ocean near geothermal vents can remain in liquid form at temperatures much higher than 100 °C (212 °F);
23 – Water can move up narrow tubes against the force of gravity in what is known as capillary action;
24 – Most people around the world have access to clean drinking water but it is a major problem in poorer areas of the world. Water pollution and low quality water can lead to dangerous bacteria, disease and viruses such as E coli and Cryptosporidium;
25 – Drinking water is needed for humans to avoid dehydration, the amount you need – each day depends on the temperature, how much activity you are involved in and other factors;
26 – It takes .26 gallons of water to irrigate one calorie of food;
27 – It takes 2.6 gallons of water to make a sheet of paper;
28 – It takes 6.3 gallons of water to make 17 ounces of plastic;
29 – It takes 924 gallons of water to produce 2.2 pounds of rice;
30 – It takes 2,641 gallons of water to make a pair of jeans;
31 – It takes 3,962 gallons of water to produce 2.2 pounds of beef;
32 – It takes 39,090 gallons of water to manufacture a new car;
33 – Two-thirds of the world’s population is projected to face water scarcity by 2025, according to the United Nations;
34 – Water is used frequently by firefighters to extinguish fires. Helicopters sometimes drop large amount of water on wildfires and bushfires to stop fires spreading and limit the damage they can cause;
35 – The water industry helps deliver water to homes in various cities and countries around the world. This can involve services such as purification, sewage treatment, filtering, distillation and plumbing;
36 – Electricity can be created from hydropower, a process that uses water to drive water turbines connected to generators. There are many hydroelectric power stations around the world;
37 – The average American, taking a 5 minute shower, uses more water than an average person in the slums of a developing country does in a whole day;
38 – Water also plays a role in cooking. Steaming and boiling food are well known cooking methods. You may have noticed this last time you made pasta or noodles;
39 – Water is also used for fun. Water sports are a very popular recreational activity and include things like swimming, surfing and water-skiing. Ice and snow is also used in ice skating, ice hockey, skiing and snowboarding;
40 – Collectively, South African women and children walk a daily distance equivalent to 16 trips to the moon and back to fetch water.
The idea of this site is, besides having fun, show the problems they need. Thinking about how we are going to consume our water is essential for the future. It is very important that we share these ideas so that everyone becomes more responsible and build a better world.
