root((HYDR))
hydraulic
1、 Relating to water; operated, moved, or brought about by means of water.
2、 Operated by the resistance or pressure of liquid forced through a small opening or tube.
🌱Without any hydraulic engineers, the country is unlikely to build many dams or reservoirs on its own. 🌳By means of a hydraulic lift, the driver can lift the bed of a dump truck with the touch of a button. He might also repair the hydraulic steering, the hydraulic brake, or the hydraulic clutch—all of which, like the lift that holds everything up, take advantage of the way liquids act under pressure. Somewhat like a pulley or a lever, a hydraulic system magnifies the effect of moderate pressure exerted over a longer distance into powerful energy for a shorter distance. dehydrate 1、 To remove water from.
2、 To deprive of energy and zest.
🌱The boy appeared at dusk staggering out of the desert, dangerously sunburned and dehydrated. 🌳Dehydrating food is a good way to preserve it; raisins, which are dehydrated grapes, are a good example. Dehydration through industrial processes makes it possible to keep food even longer and store it in a smaller space. Freeze-drying produces food that only needs rehydration—that is, the addition of water—to restore its original consistency. Runners, cyclists, and hikers fearful of dehydration seem to be constantly hydrating themselves nowadays, sometimes even using a shoulder pack with a tube going straight into the mouth. Dehydrate can also be used for making something "dry" or "lifeless"; thus, a dull teacher can dehydrate American history, and an unimaginative staging can dehydrate a great Shakespeare play. hydroelectric Having to do with the production of electricity by waterpower.
🌱A massive African hydroelectric project is creating the world's largest manmade lake, and is said to hold the key to the future for the country. 🌳The prime component of most hydroelectric systems is a dam. A high dam funnels water downward at high pressure to spin turbines, which in turn drive generators to produce high-voltage electricity. Mountainous countries with rushing rivers can produce the most hydroelectricity.Though hydroelectricity comes from a clean and completely renewable energy source, dams disrupt natural systems in a way that disturbs environmentalists. hydroponics The growing of plants in nutrient solutions, with or without supporting substances such as sand or gravel.
🌱He had never thought hydroponics produced vegetables as tasty as those grown in soil, and the tomatoes seemed particularly disappointing. 🌳Hydroponics, also known as aquaculture or tank farming, began as a way of studying scientifically the mechanisms of plant nutrition. Hydroponically grown plants may have no solid material under them at all; instead, their roots often simply hang in water with a rich mix of nutrients dissolved in it. The principal advantage to hydroponics is the savings from reduced labor costs, since it's generally carried on in enclosed areas and the irrigation and fertilizing are done mechanically. Peppers, cucumbers, and various other vegetables are produced hydroponically in huge quantities.

HYDR flows from the Greek word for "water." The "water" root can be found in the lovely flower called the hydrangea: its seed capsules resemble ancient Greek water vessels.🌸
