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.
In creases the density of the crust i think...
Answer:
107,768 ft³/hr
Explanation:
Given that :
FIELD A:
Runoff Coefficient (C1) = 0.55
Field size (s1) = 3 acre
FIELD B:
Runoff Coefficient (C2) = 0.75
Field size (s2) = 5 acre
Rainfall intensity (I) = 5.5 in/hr
We need to convert ;
Field size to ft²
1 acre = 43560 ft²
s1 = 3 acre = 43560 * 3 = 130,680 ft²
s2 = 5 acre = 43560 * 5 = 217,800 ft²
Rainfall intensity to ft/hr
1 inch = 0.0833 ft
5.5 in/ hr = (0.0833 * 5.5) ft/hr = 0.45815 ft/hr
Peak flow :
(C1 * s1 * I) + (C2 * s2 * I)
(0.55 * 130680 * 0.45815) + (0.75 * 217800 * 0.45815)
32929.0731 + 74838.8025
= 107767.8756 ft³/hr
Oceanic Trench or Deep Sea Channel, it is a narrow, long and having a sharp inclination depression in the lowermost deep-sea in which happen the extreme oceanic depths. They normally form in places where once the structure of the earth's crust plate <span>is forced below the edge of</span> another. While Abbysal plain is a beneath the surface of the water plain on the deep ocean floor, typically found at depths approximately 3,000 meters and 6,000 meters. It is in a horizontal position largely between in a mid-ocean ridge and a foot of a continental rise. Almost 50% of the Earth’s surface was sheltered by Abbysal Plains. They are the smoothest and flattest and not so discovered areas on Earth.
