THE WATER CYCLE

Let's Begin
So the water cycle starts with the evaporation of water from the oceans or seas.
As the damp air is lifted higher and higher, it cools and water vapour condenses to form clouds. Moisture is transported around the globe until it returns to the earth's surface as precipitation.

Precipitation
Rain or precipitation is formed when water vapour condenses and once the vapour becomes dense enough a water droplet is formed and precipitates down to earth.

Hail
First of all hail forms just with the uplift of air, as it gets higher and higher into the atmosphere obviously the temperature is going down so it's getting cooler and cooler so if the water gets high enough it will freeze turning it into tiny hailstones and if the winds are strong enough they will bring the hailstones up again and they will get coated with another layer of water and that water will re-freeze. That process can happen several times, that is why in intense thunderstorms you can get very large hail. So basically if the winds aren't very strong you would get the pea size hail but if the wind is very strong you could get hailstones the size of golf balls.

Ground water
Once the water reaches the ground one, of two processes may occur, one the water may evaporate back into the atmosphere or two the water may seep through the earths surface and become ground water. It then either seeps it's way to oceans, rivers and streams, or is released back into the atmosphere by transportation. The balance of water that remains on the earths surface is runoff, which empties into lakes,rivers and streams and is carried back to oceans, and the cycle starts again.

Natural factors that affect the Water cycle are :
Temperature
Location
The water could get trapped underground, this is still part of the cycle but will not move onto another stage until the water is brought to the surface.

PART 2

Greywater
Greywater is defined as waste water generated from basins, showers, baths, dishwashers etc, which can be recycled at the site where used for toilet water or constructed wetlands. Grey water can then be treated at water treatment plants to lower pollution and health risks, it is then returned into the environment. Greywater is also used to irrigate plants and soil . The plants use the contaminants of the Greywater, such as food particles, as nutrients in their growth. However some solutions such as when salt mixes into water can be toxic and cause diseases to the plant.

Blackwater
Blackwater is a term used to define waste water containing fecal matter ( poo ) or urine. It is also known foul water or sewage. Some ways to lower blackwater would be to use composting toilets which is basically a toilet that turns human waste into compost.

Whitewater
Whitewater is a term used to describe the water that comes from the town supply, up through the plumbing and into our showers, sinks,taps etc. So basically the water we would drink.

Just to clarify
So the terms "blackwater", "Greywater" and "whitewater" are used to describe the contamination levels of household water.
