The correct answer is C. Currents
Explanation
The image in the question is a map showing the North Atlantic and the Caribbean Sea. In the middle of these is a red arrow that marks the Gulf Stream. An ocean current is a massive movement of ocean and sea waters. In the case of the Gulf of Mexico current, this is originated from the movement of warm waters from the Caribbean, which are heated by the latitudinal location because it receives the sun's rays more directly. It moves in a current towards the north of the Atlantic where it is losing temperature due to the difference in the incidence of the solar rays. Therefore, the correct answer is C. Currents.

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.
