Why are tornadoes so dangerous?
Tornadoes—violent, funnel-like storms of strong winds that usually form during thunderstorms— present danger to anyone nearby. These "twisters" can demolish anything in their path, including homes, people, cars, trees, animals, and even entire communities. Sometimes lightweight mobile homes are flipped over. A strong tornado that swept into Xenia, Ohio, on April 3, 1974, leveled a farmhouse and broke everything inside, leaving only three fragile items totally intact: a mirror, a case of eggs, and a box of Christmas ornaments! Occasionally, tornadoes do other strange things—like lifting a 386-ton railway train off its tracks and dropping it 16 feet (5 meters) away! In the United States, an average of 1,000 tornadoes spin up beneath thunderstorms each year. A downward flow of cold air from clouds meets a rising flow of warm air from the ground; if atmospheric conditions are just right, a tornado starts. They occur mainly in a 10-state area known as Tornado Alley, stretching from Texas to Nebraska that also includes Colorado, Iowa, Illinois, Indiana, Missouri, and Arkansas. Most weak tornadoes last less than 10 minutes and travel short distances. Powerful tornadoes have been known to last for hours and a few have traveled more than 100 miles (161 kilometers).

    Salt: rock, sea, black, Sambar:

    Found in Sea.

    Digestion Salt stimulates digestion by increasing digestive enzymes and so benefits low appetite and indigestion. It also works directly on the taste receptors and clarifies the sense of taste. Higher doses can work as a laxative or emetic. The yogic practice of sankhapraksalana and satkarma utilises the osmotic properties of salt to draw toxins out of the mucous membranes prior to purgation (Swami Satyananda). Lungs Salt has the ability to liquefy mucus and kapha in the lungs. It dislodges deep-seated phlegm and facilitates expectoration (Bhavaprakasa). Tumours Salt has the specific ability to dissolve masses, lumps and tumours in the body. As it clears the channels it removes obstructions. Care must be taken when treating these conditions with salt due to its tendency to cause water retention. Its iodine content (especially found in sea salt) plays a part in preventing goitre. Nerves Helps to settle the nerves by descending vata and calming the emotions.
