Question

Hey! i know i already asked the first question, but i thought this might be easier! I am NOT looking for a very scientifical answer. I want a easy and simple answer for 8th grade homework. I have other questions, but they all wouldnt fit, so im gonna do another question thingy. Answer all that u know please!

Answer 1

Detrital sedimentary rocks are rocks that are formed from the remains of dead organisms.  Conglomerates are rocks that are formed by many other rocks into a new rock.
