Relative dating is when you give the age of a rock or fossil _________ to another rock or fossil.

• relative

• younger

• older

• compared

When sedimentary rock layers are deposited, younger layers are _________ of older deposits.

• top

__________ rock layers are deposited horizontally. If they are tilted, folded, or broken, it happened later.

• sedimentary
