have the continents always been where they currently are?
In 1911, a German meteorologist named Alfred Wegener began looking for additional evidence to support the idea that the continents might actually move around on the earth's surface
Wegener theorized that continents have moved overtime
Supercontinents:
In Wegener's model, he proposed that the continents were all joined at one time in Earth's history, making a supercontinent (giant landmass made up of many or all continents)
continents are large pieces of the earth's crust known as tectonic plates
pieces of the crust that move around on the earth, pushing together, pulling apart and sliding past each other - and those movements are known as plate tectonics
PANGAEA is one supercontinent in Earth's history
Moving Landmasses:
many scientists believe that there have been several supercontinents before Pangaea, and there probably will continue to be supercontinents in the far future
each landmass is still moving about the earth's surface and will continue to do so, colliding, pulling apart and sliding past other continents
