    degrees Fahrenheit or higher. That means that it
    is usually found by the equator.
  • It is about 500 kilometers wide, and winds reach
    higher than 100 miles per hour!
  • A violent tropical storm that is not found in
    any specific spot. but is most commonly found in
    the south west Atlantic ( By Florida)

How are Hurricanes classified?
  • There are four categories to classifying
    hurricanes
  • Category one winds to 74 to 95 mph, minimum
    damage

    damage
  • Category three winds of 111 to 130 mph extensive
    damage
  • Category four winds 131 to 155 mph the damage is
    extreme

How are hurricanes Produced?
Hurricanes began as storms in the hot and Moist
waters of the Atlantic Ocean and The Pacific
Ocean. The water evaporates until it goes in to
large amounts of heated moist air. They are than
twisted high in the atmosphere. Than the winds
began to circle in a clockwise direction and with
speed it gains size
5
Why are hurricanes So Dangerous?
Hurricanes are very severe storms that can damage
anything that is in its path. A hurricane 4 and
5 are so severe that it could ruin a whole city,
Just like New Orleans. Many people are than left
hurt and homeless.

Marble Question
What type of air pressure is there in a hurricane
and why?
You have 45 seconds to discuss with your group

The answer is
Low air pressure Why? Because when the molecules
heat up they spread farther apart which causes
low air pressure because there is low air density
