Question

If the same sequence of rock layers is observed over a large area, ____. a. they are probably not related b. a large deposit of rock formed over a large area c. conditions of formation were probably very different d. it is just a coincidence   Please select the best answer from the choices provided A B C D

Answer 1

B is the correct answer

Answer 2

If the same sequence of the rock layers is observed over a large area, then it indicates that a large deposit of the rock is formed over a large area. The same deposit is responsible for the formation of the rock over this large portion of the area. the mineral composition over this whole area will be similar as they are formed from the same rock deposit.

Hence, the answer is 'Option B - a large deposit of rock formed over a large area'.
