The water cycle transports a plethera of microorganisms, and many of them are harmful for human beings. These include bacteria, protozoa, viruses, and lavae of high-ordered parasytes. Some of the aforementioned are Giardia, Cyptospordium, Shigella, E. coli, hepatitis A virus, and enterovirus.

Waters can also carry chemical wastes such as pesticides, and heavy metals dissolved in them. It is common to hear about acid rain as a result of pollution, and it originates as a result of mixing sulphur dioxide and nitrogen oxide with water molecules in the atmosphere.

There are several technological improvements over the past 100 years that have made the availability of clean water to communities a lot easier, and not only depend on boiling water. Filtration is the most common practice, it traps most unwanted particles and microorganisms, but it should be accompanied with chemical disinfection, which uses halogens to oxidize essential celluar structures and enzymes. In the present, chemical disinfection can even be achieved with adding a pill to a specific volume of water.

A fault in which the hanging wall moves down relative to the footwall is a

ikadub [295]

The faults in which the hanging wall moves down relative to the footwall is called normal fault.

Explanation:

There are several types of faults based on their characteristics. One of them is the normal fault, or normal dip-slip fault. The main characteristic of this fault is that its hanging wall moves down relative to the footwall, while the footwall tends to move up relative to the hanging wall. The force that creates this type of faults is the vertical compression as the crust of Earth is lengthening.

These faults can be found all over the world, and they are actually the most common type of faults.
The normal dip-slip faults are bounding big portion of the mountains, as well as rift valleys.
As these faults progress with their formation, with the footwall going up, and the hanging wall going down, the footwall becomes a hill or a mountain, while the hanging wall becomes a valley.
The normal dip-slip faults can be found at all types of tectonic plate boundaries.
