Question

What conditions increase the chances of fossil formation?

Answer 1

After an organism's soft tissues decay in sediment, the hard parts — particularly the bones — are left behind. Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals.

Answer 2

Conditions for fossil formation.

Explanation:

All the animals and plants on this earth are not preserved as fossils.

The two most important conditions which favour the preservation of fossils are:-

1. Possession of hard part-After the death of the organisms, the soft parts are generally easily decomposed. Therefore, animals like jelly fish and insects are not ordinarily preserved.
2. Immediate Burial-If the animals and plants are not buried quickly after their death,they are likely to be destroyed by chemical decay and other agencies of erosion.
