Definition: An overflowing amount of water beyond its normal space.

How Do Floods Form?

  • Floods form when there is a lot of rain at one time for a period of days
  • When dams break from tornadoes or hurricanes all of the water that the dam was holding flows out
  • Ocean sea levels could rise and fall creating tides that can come to shore
  • tsunamis which are earthquakes in the water
  • When places get a lot of snow and it suddenly all melts there could be a lot water
  • More populated cities can get more floods because of run-off (when rain has no where to go)

What Are The Characteristics Of A Flood?

  • Types of clouds are stratocumulus and cumulonimbus which are storm clouds and are big and layered
  • Floods can last awhile depending on how much water their is
