Transcript of Hurricanes!!

All about HURRICANES Do you know what a hurricane is? a hurricane is a giant whirling wind combined with heavy rain. Hurricanes spin by the earth's rotation, in the southern part of the world Hurricanes spin in a clockwise direction while in the northern side it spins in a counter clockwise direction. damages by hurricanes are really bad because it's so strong that it could wipe out an entire forest that could have ton's of lumber, enough to build about 300,000 houses. for a hurricane to form you need the right temperature in the ocean because a hurricane forms over the ocean
you also need the depth in ocean level too

to form a hurricane the ocean temperature
has to be over 27'C and at tropical oceans
there is warm water and is very deep and for a
hurricane to form then the depth of the
warm water must be about 200 feet below.
