because this is possible if fragments of rock from 1st and then magma or lava come surrounding it and gradually loss heat and become solid . therefore sourrouding rock younger than fragment rock
Step 3
The principle of original horizontality states that __Sedimentary _____ rocks were deposited in horizontal layers. Thus, if rock layers are now _tilted (or not horizontal )____, they must have been disturbed after lithification
Step 4
The principle of _lateral contunity ______ states that rock layers extended laterally in all directions unless or until they terminate in one of a number of natural means.
Step 5
