Why are the fossils at the bottom older than the ones at the top of the soil?

Answer 1

I don't now you

Answer 2

The deeper ones were deposited first. The geologic law of superposition states that, in undisturbed strata, newer layers will be deposited over older layers; thus, in a core sample containing fossils, those samples nearest the surface will be newer in age than those beneath them. builds up like a stack of photos

Answer 3

The fossils found at the top of a canyon will probably be younger than those at the of the bottom of the canyon because the fossils at the bottom of the canyon would have been there earlier when the so called "canyon" was once a flat land, so as time went by, the flat land began growing and getting taller and finally became a canyon so the fossils at the top of the canyon WOULD be younger than those at the bottom because the bottom fossils were there before the top of the canton even existed.

Answer 4

Sedimentary rock is formed over long periods of time when sediments layer over each other and form a rock. The bottom is older because it's the first layer of sediment played down, and therefor forms first.

Answer 5

Because the ones at the bottom, the animals would have died first and soil would have covered them building a cliff and the fossils up top would have died later.

Answer 6

because the earth has layers, each layer is like a different time period, so the lowest layer would be really old, and the upper layer very new.

Answer 7

this is because older fossils have been buried in the sediments long before. The younger one which were buried in the new deposition of sediments

Answer 8

As rock builds up and buries fossils so the higher it is the more recent it is.
