Today's Fun Fact is about Continental Drift. Continental Drift is a theory made by Alfred Wegener to explain why continents shift.
Today's real lesson is transform boundaries. A transform boundary is when to plates slide and rub past each other. This is also called a strike-slip fault. The stress or tension at the boundary is called shearing. Tomorrow will be about Convergent Boundaries.
Convergent boundaries are when oceanic crust goes under continental crust. These are also called subduction. These boundaries form mountains. The reason the ocean crust goes under is because it is more dense than continental crust.
