Since only 3% of water is usable as fresh water, 2% is unavailable in frozen form leaving approximately 1% of the earth's water usable.
Water can be made usable through processes such as filtration, disinfection (using methods like chlorination or UV treatment), and desalination for removing impurities and contaminants. These methods help make water safe for drinking and other uses.
Salt water can be made usable by desalination, which is the process of removing the salt and minerals from the water. This can be done through methods like distillation, reverse osmosis, or electrodialysis. The resulting fresh water can then be used for drinking, irrigation, and other purposes.
The percentage of oxygen by mass in water is approximately 88.8%.
To calculate the percentage of water in a hydrate, you first determine the molar mass of the water and the compound. Then, you divide the molar mass of the water by the molar mass of the hydrate and multiply by 100 to get the percentage.
Clean usable water can become toxic due to pollution from industrial waste, agricultural runoff, or chemicals like heavy metals or pesticides. Natural disasters such as oil spills or harmful algal blooms can also contaminate water sources and make them unsafe for consumption. Additionally, improper disposal of hazardous waste or sewage leakage can introduce harmful pathogens into the water supply.
97% is all salt water and 3% is water used by people.
Earth's usable water is primarily found in the form of surface water in lakes, rivers, and oceans, and in underground aquifers. This water is essential for activities such as drinking, agriculture, and industry. However, only a small percentage of Earth's total water supply is considered usable for human consumption and activities.
The total amount of Earths total water supply that is usable fresh water is less then two percent. The rest is salt water or pond water.
it comes from mountains and the sky which is rain.
