Question

Fossils change through a section of rocks because ______. Multiple choice question. each species has its own level of magnetism, with some species being magnetically drawn closer to Earth's core different species were alive during different periods of time the heavier fossils move to the bottom of the rock layers, and the lighter fossils remain closer to the surface

Answer 1

the organism at the lowest level is a more simpler organism but as years pass each layer we can see how that organism is evolving to become more complex. Each layer contains a organism developing and becoming more complex. After the organism has been buried, more sediment, volcanic ash or lava can build up over the top of the buried organism and eventually all the layers harden into rock.
