Question

What evidence exists to support the theory of plate tectonics?

Fossils of ancient animals are found on the ocean floor.
Mid-ocean ridges were found to not exist.
The seafloor has less sediment and is youngest at mid-ocean ridges.
Rock formations in deserts show evidence of erosion from glaciers.

Answer 1

the seafloor is the correct answer

Answer 2

Answer: Option (3)

Hence the correct answer is option (3)
