The process of fossil occurrence

Fossils occur when the bodies of animals that have died, are slowly accumulated by a layer of soil. For millions of years, the land stockpiling the fossils will be increasingly layered and slowly petrified. Millions of years later, the fossil was discovered by humans. How can the fossils accumulated in the soil layer rise into the soil on the surface of the soil? The ground that you are grounding is not silent, but always moves. Sometimes it moves upward, sometimes also moving downwards.

The movement of the soil layer can be felt when an earthquake occurs. After several million years, the soil layers that were once under the bottom will slowly rise upward. Of course the fossils in the soil layers will also come up. That's when the fossils can be found not far from the ground.
