Question

Which of the following could be a method used to estimate the age of an ancient rock? To find out its mineral composition To find the age of the fossils trapped in it To calculate the amount of C-14 atoms left in it To calculate the number of sediment layers in it

Answer 1

I’m pretty sure the answer would be Carbon dating

Answer 2

i believe it would be to calculate the amount of C-14 atoms left. scientists began to find out how long an object has been decaying, this has to do with half lifes etc. and how long a specific mineral/elements half life is. they use this to calculate how old it is (not an exact age but it's very accurate.)
