Question: List the principles you used to determine the age relationships:

Crosscutting, Superposition, Original Horizontality

Explanation:

Superposition means that the layer of rocks that was deposited first must be on the bottom unless overturned by some geologic even later on. In this case, that allows us to confirm that D is younger than H because D was deposited on top of H.

Crosscutting is also used, which is where you see your faults. Think logically: for something to cut across a layer of rock, the layer of rock must exist to be cut across. This principle makes letter B younger than letters C, A, and F, but older than H, as B does not cross cut H.

Original Horizontality is also used. This simply means that when a layer of rocks is deposited it is deposited roughly horizontally. This in essence is saying for example, that layer C was originally deposited completely flat, like a brick. Then, letter B came along later and cracked the brick in half, then pushed one half of the brick up, making the brick (layer of rock) uneven.

Make sense enough?

not: both offer magnification to the atomic level.
