20) Why do metamorphic rocks rarely contain fossils?
A
The rock formation occurs from extremely hot magma deep inside the crust where organisms do not live

These rocks undergo extremely high pressure or temperature changes when formed, which would destroy fossils.
C
These rocks are usually formed from extremely hot magma or with severe lava explosions, which would destroy fossils.
D
These rocks are formed underwater, and the water dissolves the fossils.
