Plate Tectonics Mind Map

Plate Tectonics Mind Map

1. Alfred Wegener:

   • In 1915, he made his first theory.
   • In 1912, Alfred Wegener wrote his first boook and published "The Origin of Continents and Oceans."

2. Plate Tectonics

   • The Earth's surface is made up of stiff rock slabs, or plates, that move in relation to one another.
   • Convection, or heat transfer generated by the motion of a heated magma fluid in the Earth's interior, causes plate movement.
   • Three plates influence Guatemala, which are: the North American Plate, the Caribbean Plate, and the Copos Plate.

3. Spreading of the Seafloor

   • The ocean floor was the first piece of evidence.
   • As you get further away from the mid-ocean ridge, the thickness of the sediment layer and the ocean floor rise.
   • The process of new oceanic crust forming along a mid-ocean ridge while older oceanic crust moves away from it.

4. Harry Hess

   • He was on a mission to investigate the innermost layer of the sea floor.
   • In 1960, he suggested that continent movement was caused by seafloor spreading.
   • Was an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics.
