  • How does the Theory of Plate Tectonics explain the location of same fossils at Points A and B?
    The continents were once joined together.
    The animals swam from one continent to the other
    Humans transported the animals from point A to point B.
    The animals developed independently on both continents.

    A transform boundary is forming.
    A mid-ocean ridge is forming.
    Subduction--oceanic crust is denser than continental.
