Answer:
The correct answer is principle of superimposition.
Explanation:
According to the superimposition principle, in the undisturbed rocks, the youngest rocks are situated on the top and the oldest rocks are found in the bottom. The phenomenon takes place due to withering. The rocks get withered because of the influence of air and water.
The soil particles or the sediments get gathered at another site. The deposits of sediments get concentrated with time and result in the production of rocks. The mature rocks get surrounded by the layers of sediments with time passing by. These sediments get concentrated again to produce novel rocks. Through this procedure, the fresh young rocks get produced over the older ones.

If you go to the beach, and try making balls in your hand it's nearly impossible. If you pick up sand it will just fall through the crevice's in your hand, or a simple movement of your hand can make the sand fall. Sand simply can't be formed into a ball.
If you where to try making a ball of sand the outcome wouldn't be great. Even if you made the sand damp you still can't really make a ball of sand.
