Drag each tile to the correct box.<br> Arrange the layers and faults from oldest to youngest.
kaheart [24]

The answers would be:

Layer D

Layer C

Layer B

Layer A

Layer E

Fault F

If you'd like to know why, here's more about the question:

The law of superpo sition states that the lower the layer, the older the rock is.

Looking at the layers alone, we can say that D is the oldest, and C would be next, so on and so forth.

The law of cross - cutt ing relationships, on the other hand, states that a geologic event, like a fault, is younger than the layer that it goes through.

So if we look at the figure given, the fault goes through all the layers, so we can say that it is younger than all the layers.
