Will Give Brainliest How could any rock change into a sediment and then go back into a sedimentary rock?

A rock can become a sediments through erosion or weathering. These sediments can then compress and compact to become a sedimentary rock.

As successive layers of sediment settle on top of one another, the sediment near the bottom is compressed, hardens, and forms sedimentary rock. Sedimentary rock may be broken down into sediment once again by weathering and erosion

1) Mutations are caused by changes in nucleotide bases. these altered base formed different amino acid depending upon nucleotide base sequence that code specific amino acid. ... even though some mutations, can have a more effect on amino acid coding, which can affect what kind of proteins are produced.
