Volcanic ash has occasionally formed molds of animals. this occurs when the ash covers the animal and -

Out of the following given choice;

F.  replaces the animal's soft tissues.

G.  enters the animal's body cavity.

H.  hardens before the animal decays.

J.  mineralizes the animal's bones.

The answer H. This can be caused by hot pyroclastic flows or falling volcanic ash from the atmosphere following a volcanic eruption. The ash buries animals and plants intact without moving them and without completely crushing or burning them. Over time excess silica dissolved in the water often replaces soft bone materials molecule by molecule, creating an almost indestructible fossil (like petrified wood) that lasts for millions of years

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
