A
These folded rock strata are the oldest features. Features B, D, and F cut through them, so you know by cross-cutting relations that B, D, and F are younger than A. Features C and E are on top of them, so you know by superposition that C and E are younger than A.
B
This is a magma body that welled up into the crust. It has to be younger than A because it cuts through A. But it must be older than D and F because D and F cut through it. By superposition, you know that it is older than C and E.
C
This rock layer must be younger than A by superposition. However, it is older than D because D cuts through it.
D
By the principle of cross-cutting relations you know that this dike is younger than A, B, and C because it cuts through them. By superposition, it is older than E because it lies below E.
E
This sedimentary rock layer is younger than A through D because it lies over the other features; thus by superposition, you know it is younger than them. It is older than F because F cuts through E; by cross-cutting relations you know that F is younger than E.
F
This fault line is the youngest feature. It cuts through features A, B, C, and E so by cross-cutting relations it must be younger than them. Since it cuts through E but D does not, then F must also be younger than D.

Answer 3

This is a big chunk of work for anyone. Is it possible for you to get started, doing whatever you can, and writing out questions for possible helpers as you go? You'll have far better luck getting help if you divide up this problem into manageable parts.
