Alex listed the typical steps of fossil formation.

1) An organism dies.
2) The remains fall to the bottom of the ocean.
3) The soft portions decay, and the hard portions remain.
4) The sediment becomes rock.

Which statement describes the missing step?

After step 3, layers of sediment cover the dead organism.
After step 1, minerals dissolve the dead organism.
After step 4, layers of sediment cover the dead organism.
After step 2, minerals dissolve the dead organism.

1 answer

The correct statement that describes the missing step is:

After step 2, minerals dissolve the dead organism.

This step is important because it explains how the hard parts of the organism can be replaced by minerals over time, leading to fossilization.
