Question

The theory of plate tectonics is supported by evidence that some sediment layers on the floor of the Atlantic Ocean are thinner than expected. How does this observation support the theory of plate tectonics?

A. It suggests that ocean waters move quickly over this layer.
B. It suggests that ocean waters move slowly over this layer.
C. It suggests that the deposits are older than surrounding layers.
D. It suggests that the deposits are younger than surrounding layers.

Answer 1

I think the answer is D. because when plate tectonics slide together the older layer slides underneath the newer layer.
I hope this helps
  

Answer 2

Answer:

D. It suggests that the deposits are younger than surrounding layers.

Explanation:

The theory of plate tectonics claims that the outer shell of the Earth is divided into plates that glide over the mantle, with the rocky inner layer above the core. Thus, the ocean floor is much younger because new crust is produced there.
