State and explain too types of water State seven uses of water Define water pollution and state five causes of water pollution . ?

1. Freshwater: Freshwater is water that contains low levels of dissolved salts and is found in rivers, lakes, and underground sources such as aquifers. It is essential for drinking, agriculture, and industrial processes.

2. Saltwater: Saltwater, also known as seawater, contains high levels of dissolved salts and is found in oceans and seas. It is not suitable for drinking or irrigation without desalination, but is important for marine life and transportation.

Seven uses of water:
1. Drinking and cooking
2. Agriculture and irrigation
3. Industrial processes
4. Hygiene and sanitation
5. Recreation and leisure
6. Energy production
7. Transportation

Water pollution is the contamination of water bodies, such as rivers, lakes, and oceans, with harmful substances. This can have detrimental effects on aquatic ecosystems and human health.

Five causes of water pollution:
1. Industrial discharge: Chemicals and pollutants from factories and manufacturing processes can be released into water bodies.
2. Agricultural runoff: Pesticides, fertilizers, and animal waste from farms can seep into water sources.
3. Sewage and wastewater: Improperly treated sewage and wastewater can introduce harmful bacteria and pathogens into water bodies.
4. Oil spills: Accidental or deliberate releases of oil from ships or offshore drilling platforms can contaminate water and harm marine life.
5. Plastic pollution: Discarded plastic waste can accumulate in water bodies, posing a threat to aquatic animals and ecosystems.
