Which process is included in the formation of both metamorphic and sedimentary rock? A.
heating
B.
recrystallization
C.
compaction
D.
weathering

C.  compaction

Explanation:

The weight on the lower layers increases as the layers of sediment stack up. The soils are pressed together, squeezing out some water mixing in with the sediments. This approach is known as compaction.

The sedimentary series has formed into a sedimentary stone following compaction and cementation.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
