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:
Towns grew up along the rivers which had access to the sea. Rivers also provided protection from invaders. Farmers grew crops in the fertile fields that surrounded the towns. The lack of mountains was good for farming, but it made the towns easier to be invaded by enemies.

<span>A climate cycle in the Pacific Ocean with a global impact on weather patterns is called El Nino. The cycle begins when warm water in the western tropical Pacific Ocean and shifts eastward along the equator toward the coast of South America.
La Nina has cooler temperatures, not warmer ones. Temperature inversion is just a simple change of temperature. And global warming doesn't fit here as it is not a type of current.</span>
<h2>Answer:</h2>
Balanced forces/Resultant force/ Newton's first law/law of inertia.
<h3>Explanation:</h3><h3>Balanced forces/Resultant force/ Newton's first law/law of inertia:</h3>
It says that each article will remain in its state of rest or similar motion in a straight line except a resultant force works on it. It is known as the law of inertia.
The inertia of the body is the hesitation of the target to alter its state of peace or movement.
The inertia of an article depends on its size. The greater the body, the greater the inertia. It shows it is difficult to start moving, stop, slow down, speed up or change direction. Force is required to overcome inertia.
