Select modern day evidence to support Plate Tectonics.
A rift was found on the ocean floor between Africa and S. America.
The ocean floor is made of basalt
Ocean waves point towards the continents.
The ocean floor was layered with eroded continent.
Select modern day evidence to support Plate Tectonics.
Dinosaur bones are found on all the continents
Bands of alternating magnetism match up on either side of the mid-ocean ridge.
Bands of potassium 40 increase the further from the rift between Africa and S. America.
Butterflies migrate between the continents showing that they were once connected.
Select modern day evidence to support Plate Tectonics.
The age of rock increases further from the mid-Atlantic rift
The age of rock decreases further from the mid-Atlantic rift

The moon orbits the Earth
Patterns on the moon match up with continental patterns on the Earth.
Bouncing lasers off the moon can measure continental movement.
Bouncing lasers from the moon can measure the rate of sea-floor spreading.
How is the age of oceanic rock often determined?
By tasting the rock. The saltier the older the rock.
By comparing the amount of potassium-40 to Argon-40.
By comparing the location of rock in relation to the continents.
By how much the rock sinks in the ocean.
