the diagram below represents a cross - section of a cliff. it shows several rock layers containing fossils. how is a cross - section, like the one above, most likely help to identify the age of different rocks and fossils on earth?
Answer
Brief Explanations:
The principle of superposition in geology states that in undisturbed rock - layers, the oldest layers are at the bottom and the youngest are at the top. By looking at the order of rock layers and the fossils they contain in a cross - section, we can determine relative ages. Fossils are also index fossils for certain time periods.
Answer:
The cross - section helps identify the age of rocks and fossils by showing the order of rock layers (older layers at the bottom, younger at the top) and the types of fossils in each layer, which can be used as index fossils for relative dating.
