Question

Which of the following is TRUE about sedimentary rock?

A. does not contain layers
B. May contain fossils
C. the hardest of the rock types​

Answer 1

B.May contain fossil.

Step-by-step explanation:

Answer 2

B

Step-by-step explanation:

Sedimentary rock is layered. That makes A wrong, but it leads to another observation.

Things can die and think sink to the bottom of an ocean or sea or river or lake bed which over time changes. So you might find fossils which is the answer.

C is incorrect because there are much harder substances than sedimentary rock.
