The Water in Earth

The amount of fresh water in our planet astonishingly low, this process starts with evaporation, which takes place due to high temperatures were the water from lakes or seas evaporates and  reaches clouds, where it cools and condensates and turns into liquid again. The last process is called precipitation, where the water reaches the ground again, the most common form of precipitation is rain.  The water isn’t distributed equally around the world, there are countries which are water rich and countries which are water poor. The water rich countries may have lots of land to fall on; they may have great rivers flowing through them or underground water reserves which are able to supply them effectively.  Water poor countries are mostly deserts with very few water sources. They most probably don’t have rivers or underground water reserves that they can use. They can also be small countries were there isn’t enough land to retain the water. This shows you that water isn’t always where you need it.

  1. Valentín, this is a good description of the functioning of the water cycle and of water distribution. It would be great if you also gave your opinion about the problem of water as I have asked you.
