Reading Passage 1  

Hurricanes are severe tropical storms that from in the Southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the Eastern Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power. Hurricanes rotate in a counter-clockwise direction around an “eye”. Hurricanes have winds of at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and huge waves can damage buildings, trees and cars. The gigantic waves are called a storm surge. Storm surges are very dangerous and a major reason why you must stay away from the ocean during a hurricane warning or hurricane. Scientists have only been studying hurricanes for about 100 years. But there is evidence of hurricanes occurring long in the past. As one example, American geologists believe that the layers of sediment in a lake in the state of Alabama, USA were brought there by a hurricane in the Gulf of Mexico as long as 3,000 years ago. One of the first human records of hurricanes appears in Mayan civilization originated in the Yucatan around 2600 B.C. and they rose to prominence around A.D. 250 in present-day southern Mexico, Guatemala, western Honduras, El Salvador, and northern Belize. The Mayans also showed their respect for hurricanes by building their major settlements away from the hurricane-prone coastline. In fact, it is the Mayan word “Hurakan” that became our word “Hurricane”. Hurakan was the name of one of their gods, who, they believed, blew his breath across the water and brought forth dry land. Later, Carib Indians gave the name “Hurican” to one of their gods of evil. Many storms have left important marks on history. In 1565, a hurricane scattered a French fleet of war ships and allowed the Spanish to capture a French fort in what is now the North American state of Florida. In 1609, a fleet of ships carrying settlers from England to Virginia USA was struck by a hurricane. Some of the ships were damaged and part of the fleet grounded on Bermuda, an island nation in the Atlantic. These passengers became the first people to live on Bermuda. In 1640, a hurricane partially destroyed a large Dutch fleet that was poised to attack Cuba. There were a number of particularly severe hurricanes as the U.S. went from the 1800s to the 1900s. Hurricanes hit Louisiana, South Carolina and Georgia in 1893 and killed as many as 4,000 people. In 1900, a famous Texas hurricane killed more than 8,000 people and was a Category 4 storm. Hurricanes are classified into five categories, based on their wind speeds and potential to cause damage. The first category includes winds of 74 to 95 miles per hour, the second 96 to 110 and the third 111 to 130. In the fourth category the wind speeds are category includes winds of 74 to 95 miles per hour, the second 96 to 110 and the third 111 to 130. In the fourth category the wind speeds are of 131 to 155 miles per hour. As forecasting improved communities were no longer surprised by hurricanes and could take measures to evacuate ahead of the storm. While destruction still continues, the number of deaths in hurricanes has dropped significantly.
