Plate Techtonics

Teacher: Ms. Austin
Across
the idea that the continents slowly moved over Earth's surface
mountain ridges formed that ran along the middle of some oceans floors
plates move apart, or diverge, from each other
plates come together, or converge, plates come together
all the continents together to make one super continent
a trace of an ancient organism that has been preserved in rock
Down
plates slip along each other
mountain ridges continually adding new material to the ocean floor
when the ocean floor sinks into a deep ocean trench into the mantle again
under water canyons
