The Theory of Plate Tectonics
Plate Tectonics is the geological
theory that states that pieces of Earth’s lithosphere are in constant, slow motion, driven by convection currents in
the mantle.
The theory of plate tectonics explains the formation, movement, and subduction of Earth’s plates.
The plates fit closely together along cracks in the crust.
They float on top of the asthenosphere.
They
carry the continents, parts of the ocean floor, or both.
The
edges of the different plates meet at lines called plate boundaries.
A transform boundary is a place
where two plates slip past each other, moving in the opposite direction.
A divergent boundary is
where two plates are moving apart, or diverge.
A convergent boundary is where two
plates come together, or collide.
