Question

Sedimentary rocks formed from the remains of once-living things are ____.

Answer 1

I think it may be metamorphic

Answer 2

Sedimentary rocks formed from the remains of once-living things are ____.

Organic. Sedimentary rocks a formed from the remains of organic living things that once lived. A little down the road from biology you will learn about chemistry, which teaches us carbon is found in all organic matter, but \(\textbf{NOT}\) in inorganic matter. (So that is a major factor hence, organic being my thought of the answer.)

Note:
This question does not give the answer choices, and I have no ability to see what you are learning, my answer is just an educated guess.

Peace.
