PLZ help! examine the layers of rock. how does layering provide evidence for determining geologic age?

the lowest the layer, the older the rock

Explanation:

If the rock is at the top, it is the youngest and if it is at the bottom, it is the oldest. This is what i remember from 6th grade, hope this kind of helps.

Not sure the best way to word it but here

Layering provides evidence for geologic age because distinction between layers shows that something had changed in the environment at that time, you can also tell the age through which layers are closer to the top, those layers being the youngest, and which layers are further down, those being the oldest

Explanation:

So that’s best way I could think to word it, but basically the layers are different types of souls and have different fossils in them, sometimes there will even be layers of ash if there was a large fire, so you can see what was going on at the time, the top layers being the most recent
