Irrigation machinery has <u>quadrupled </u>the amount of irrigated land in the US.
Irrigation refers to the act of artificially providing water to land to support the development of crops. It is an antiquated agrarian system and may have been honed as ahead of schedule as 5000 B.C. along the banks of such consistently flooding streams as the Nile. Channels were burrowed to broaden the region secured by the surge, and dams were raised to trap water on the land after the floodwaters had died down. The advancement of preoccupation dams and of water-lifting machines allowed the water system of terrains lying over those typically come to by floodwaters. Remainders of these antiquated structures have been found in Egypt, where all farmlands are flooded; Iraq; Lebanon; Syria; China; India; Peru; Mexico; and the United States. Present day water system frameworks are as yet in view of these two key building developments.
Answer:
D. set it outside and check on it every day
Explanation:
In order for Brittany to be able to study the soil erosion by using a simplified method of what the farmers do on the slopes to minimize it, she will need to take the pan, leave it outside, and check on it every day. By having the required shape, the soil will give somewhat an example of the soil on the slopes that has been plowed so that the furrows run along the hills. Since the hills do not move or tilt, the pan with the soil should be stable, static. Being put outside, it will be exposed to the natural conditions that cause the erosion, such as the water and wind. Brittany will need to check upon the soil every day and make detailed notes and measurements to see what the erosive effects are on it.
Answer:
Caucasus Mountains separates Europe from SouthWest Asia.
Explanation:
Caucasus is mountain range that streches between Blask Sea and Caspian Sea in west-east direction. This range is politically located in parts of Russia, Georgia, Azerbaijan and Armenia. It's highest point is Elbrus (5,642 m).

Answer:
<u>Waste water is any water that is affected by human use and is combination of all domestic, industrial and agricultural stuff</u>s.
Explanation:
- It can be also called as the stormwater or surface runoff, or sewer infiltration. This type of water can include the domestic wastes involved in households like toilet flushes, dishwashers, washing machines, and detergents. This type of water in developing countries if often treated with septic tanks, drain fields, and onsite sewage systems.
- Chemical or physical pollutants include heavy metals, organic and inorganic soluble matter such as urea, gases as hydrogen sulfide, various oxides and toxins of pesticides and methane.
- Use of micropollutants like plastics, and thermal pollutants like heat energies derived from the power station and industrial manufactures. Certain biological sources of pollutants like Bacteria, Virus, and Protozoa, and parasites like organisms.
- It can include parasitic like insects, arthropods, and others that reduce the biological oxygen capacity of the freshwater stream and decline in the fish population due to the nutrification of water and contaminants due to the wastewaters.
