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.
<span>1) The main factor that could hinder the forward progress of a message in a bottle in an ocean current is "Great Pacific Garbage Patch." which size is similar to one of Texas. It is a gyre of marine debris particles that contains a huge amount of pelagic plastics, chemical sludge and other debris that currents usually bring.
2) The factor which could aid the movement is the force of a current which would take the bottle and the path of the current that flows in the right direction.According to the statistics of related investigations, this factor seems to be the only one that could could positively aid the movement.<span>

Answer:
The sun
Explanation:
The sun drives the water cycle. The sun evaporates water from the oceans, seas, lakes and other bodies of water and also from plants through the process of transpiration. The evaporated water then forms into clouds and when it gains enough mass it falls back to Earth. This is a closed system so that means that this is the same amount of water that has always been present on Earth.
It's gets colder, wetter, and not much sun is received.
