19. What is the law of superposition? A Igneous rock is older than nearby sedimentary rock, which le older than
nearby metamorphic rock.
B A sedimentary rook layer in its original position is older than the layers
above it and younger than the layers below it
C Metamorphic rock le older than nearby sedimentary rock because
sedimentary rock is deposited before metamorphle rook forms
D. The exact age of a sedimentary rock layer can be found using the layers
above and below it, even if the layers are not in their origina positions
