how is a cross - section, like the one above, most likely help to identify the age of different rocks and fossils on earth? a the layers accumulate as time passes creating a visible timeline of earths life forms and rock compositions. b the layers can be used to see every species of life that was present at each time in earths history. c the layers show how long it takes for rocks and fossils to form from sediments and decaying plants and animals. d the layers provide specific dates to scientists as to when each animal lived and died and when each rock was formed
Answer
Brief Explanations:
The principle of superposition in geology states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top. Rock - and fossil - containing layers accumulate over time, creating a chronological record. Option A correctly describes this concept. Option B is incorrect because it's not possible to see every species in the layers. Option C is wrong as the layers don't directly show the formation time of rocks and fossils. Option D is incorrect since rock layers don't provide specific dates for when animals lived/died or rocks formed without additional dating techniques.
Answer:
A. The layers accumulate as time passes creating a visible timeline of Earth’s life forms and rock compositions
