The Water Cycle

Here there is kind of a summery I made about the water cycle: It’s definition, how it happens and what is the problem that’s affecting this process.

The hydrological cycle, better known as the water cycle, is the process that recycles water and nutrients. It’s the continuous exchange of water between land and water-bodies.
It begins when water from differents places (oceans, rivers, lakes, ponds, puddles, etc) evaporates going up to the sky and formed into clouds while being cooled. So once clouds are filled with more water, precipitation occurs, and waters comes back (in form of rain, ice, sleet or snow) And now just 2 things can happen: Water could become part of the ground, flowing into oceans or lakes by rivers and streams. Or it just could go back up to the atmosphere and the cycle begins again.

It is very important for this to occur because it gives fresh water to every living being in the world. Approximately 97% of the earth’s water is stored in the oceans, and only a fraction of the remaining portion is usable freshwater. So if the urbanization alter the natural amount of water that should go into ocean and lakes, the consequences could be a decrease in the volume of water that percolates into the ground and in the quality of water as well. These type of hydrological changes actually ARE having significant implications for the quantity of clean and fresh water that is available for the use of humans and wildlife.
