1.which evidence would confirm that a given rock layer is newer than the layers around it?

It has been crumpled and folded, while the other layers lie flat.

Other layers have been deposited above it.

It is horizontally-oriented.

It cuts through all the other layers.(this)

i think its C or D but im not sure.

2.which of the following are methods of relative aging of rocks? (three answers)

superposition(this)

horizontal relationships

angular relationships

cross-cutting relationships(this)

original angularity

faunal succession(this)

if any of these are wrong please explain so i know next time.
