Hi, sounds like it would turn into B). Metamorphic Rock. Igneous rocks are only formed when melted rock hardens and solidifies. Sediimentary rock is formed when sediment is deposited out of air, ice, wind, gravity or even water. I Doubt it would remain a sedimentary rock so the best answer would be metamorphic rock. Hope this was correct. :)
Answer:
I would say fossil evidence because fossil and rock clues are what led to Wegener's theory of Continental Drift
Answer:
Argon
Explanation:
Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.
Here's a link with some cool info on it:

I believe the answer is linear :)
