Ah yeah, I wasn't sure about the difference between those two terms.

What's the difference between a syncline and an anticline? What's the difference between a syncline and a synform?
When the earth is in wavy-folds, the syncline is folded around the baby rocks, and the anticline is folded around old rocks. A syncline is the fold, and the synform is that the fold is pointed? down

`A syncline has youngest layers closer to the middle while an anticline has youngest layers farthest from the middle. A synform is a downward fold. Synclines are usually synforms but may be overturned to become antiformal synclines.`
Your turn!

(sorry, picture is huge)

If apparent bed thickness xy equals 15 units, please give true bed thickness to the nearest hundredth unit. Never trust image proportions.

I believe it's
`15cos 25° = 13.6 (or 14 if we're going with sigfigs)`
I can post an explanation of how I got that if anyone wants.

Correct! I did sin(90)/15=sin(25)/x, (x=c) but your way works fine.

Please do explain. (also 13.6 only goes to the tenth, doesn't it?)

Wait I misread the problem lol never mind my answer, freed2003 is correct.

Describe Horsts and Grabens along with their cause.
`Horsts and grabens are created when land is sandwiched between two normal faults. Horsts are raised, and grabens are lowered.`
