  3. Here is a clue!

  4. What is a Hurricane?Hurricanes are born over very warm oceans. They can occur at any tome of year although they usually happen from May to December. They begin as areas of heavy showers where warm, moist air rises and cools to form rain clouds thousands of metres high. As this air rises, an area of low pressure develops. The clouds start to spin around the low pressure and suck up moisture. The centre of the storm – called the eye is an area of descending air.

  5. Hurricane facts Hurricanes usually only last about one week but sometimes the storms grow over 800km across and can last for up to 3 weeks. When hurricanes drift over land or away from the Equator they begin to die – this is because they need a warm ocean power source to feed them warm, humid air.

  6. Hurricane facts Where do Hurricanes happen? Hurricanes develop over the sun-warmed tropical waters of the oceans. They generally are carried up away from the Equator.

  7. Hurricane facts • What are the effects? • Hurricanes destroy lives and property in 3 main ways: • Wind speeds of over 150mph uproot trees, flatten crops and houses, turn over cars and batter shipping • Very low air pressure and high winds causes a storm surge which when it hits land can cause flooding • Very heavy rain adds to flooding and crop damage
