Rock layers in order is basically natures calendar.
The highest layer is the newest formed layer
While the deepest layer was the oldest and probably has been there from some time
And everything in between goes accordingly
So putting rocks in order by age helps scientists better understand what was there before what and how the rocks changed over time.
Hope this helps!

Potential Energy
The potential energy gained is 43750 J
Explanation:
Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.
For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.
Potential Energy is defined as
Potential energy = Mass * height
Given Mass M = 1250 N
Given height h = 35 m
So the potential energy = 1250 * 35 = 43750 J
Thus the potential energy is 43750 J
Answer:
Genetic variation.
Explanation:
It is caused by genes inherited from parents to offspring. It is a result of genetic information from parents.
