  1. Hot Spots By: Brenna, Emily, and Nadine

  2. What are Hot Spots? • A hotspot is a location on the Earth's surface that has experienced active volcanoes for a long period of time • Hot spots are formed by mantle plumes

  3. Mantle Plumes • Are unusually hot regions of the mantle • Originate deep in the mantle • Intense heat melts rocks • The melted rocks are now forced to rise towards the surface, which becomes magma • The magma then forms volcanoes • Eventually, as the volcanoes get older, they will eventually form a plate over a hot spot

  4. Effect on Crust • Some effects of the crust are: • Volcanic chains • Seamount chains • Flood basalts • Form flat plains or plateaus

  5. Formation of the Hawaiian Islands • The Hawaiian Islands were formed by a hot spot under the Pacific Ocean • The Pacific Plate kept sliding and more islands were formed. • This is because as the plate moves over the hot spot, and the mantle plumes push magma up to the crust. • The plate keeps moving and form more volcanoes

  6. Stationary Hot Spot • It is a hot spot that does not move • A stationary spot formed the Hawaiian islands as well as the Emperor Seamounts

  7. Moving Plate

  8. Did the Pacific Plate Change Direction?
