Kelli drew a diagram to compare cast and imprint fossils.

Question

Which label belongs in the area marked Y?

Involves minerals replacing remains of organism
Takes millions of years to form
Gives evidence of organism's activity
Involves mold filling with minerals and sediment

Answer 1

The label that belongs in the area marked Y is "Involves minerals replacing remains of organism."

This is because cast fossils are formed when minerals fill in a mold of an organism, creating a replica of the original remains, which often involves the process of mineral replacement.
