Sparks fly.The odds of being struck by lightning lightning, electrical discharge accompanied by thunder, commonly occurring during a thunderstorm are about I in 700,000. But University of Florida University of Florida is the third-largest university in the United States, with 50,912 students (as of Fall 2006) and has the eighth-largest budget (nearly $1.9 billion per year). UF is home to 16 colleges and more than 150 research centers and institutes. researchers claim those odds could increase as more lightning occurs due to warmer, wetter summers. The culprit may be global warming global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. . Moist, warm air causes positive and negative electrical charges to separate between the top and bottom of a cloud. In turn, the negatively charged Adj. 1. negatively charged - having a negative charge; "electrons are negative" electronegative, negative charged - of a particle or body or system; having a net amount of positive or negative electric charge; "charged particles"; "a charged battery" cloud bottom repels electrons in objects on the ground, giving them positive charges. Electric current then flows between the oppositely charged poles to create lightning. |
