I'm not sure why you also put this in religion, but scientists study rock layers because they can tell us a lot about the past based on different types of rock and types of things in the rock.

You can tell the age of the layers. The bottom layer is the oldest and the top is the youngest. When the layers are disturbed they tend to get bent and messed up and you cannot tell the age
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.

sedimentary rock is a multiple of layers
The hard ones.
it's layers of rock tell us about the past
Yes. The layers, the fossils inside, and the types of crystals found within all tell a story.A2: Not literally, but a rock has a story to tell if you know geology.

yes
When you look at a rock that has undisturbed layers, the bottom layers are older and the upper layers are younger. Anytime a rock layer crosses another (ie. an intrusion), the crossing layer is younger.
Unless disturbed by later events, younger layers overlie older layers. See the law of super-position.
