Answer: The process of reducing or removing minerals from water is called desalination.
Explanation:
The most commonly involved in this process is seawater, which by its nature contains large amounts of salt. This process makes it possible to remove salt from the water and obtain drinking water. The coastal and island regions often have great difficulty in supplying drinking and process water. As a result, permanent or occasional shortages of water and all the resulting consequences are becoming increasingly frequent.
Furthermore, in the future, due to a possible lack of water, this process could be crucial in supplying humanity with drinking water. Today, some countries (such as Saudi Arabia) that have a water scarcity problem are actively using this technique to supplement the required quantities of water.
Answer:
(1) Less
Explanation:
Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
Answer:
Non point sources
Explanation:
A point source is usually a single known source of a pollution such as emission of toxic fluids from a company directly into water bodies.
Runoff of eroded soil and chemicals such as fertilizers and pesticides from cropland, feedlots, logged forests, urban streets, parking lots, lawns, and golf courses are examples of non point sources as there is no main known source of the pollution.
