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:
ISCO-DUG-WUAZ
Explanation:
Seismic waves of an earthquakes is recorded first in the station closest to the earthquake. The P wave is the faster moving wave and then the S wave. The faster the time it takes the P and S waves to register in the seismographer the closer the station to the site of the earthquake. Bearing this in mind, the wave was first registered in ISCO making it closest to the earthquake site, followed by DUG and then WAUZ.
ISCO (14sec)-DUG (57sec)-WUAZ (73sec)
