GEOLOGY

Detailed explanation-1: -The rock layers get older as you dig deeper. The layers position does not necessarily tell you about the age. The youngest is always on the bottom.

Detailed explanation-2: -The positions of fossils in rocks indicate their relative ages; older fossils and rock layers are deeper than fossils and rocks that are more recent.

Detailed explanation-3: -Final answer: If the fossil of an organism is found in the deeper layers of the Earth, then we can predict that the extinction of organisms occurred thousands of years ago.

Detailed explanation-4: -The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.

Detailed explanation-5: -Why do older fossils tend to be in deeper layers than the younger ones? When sedimentary layers form, it is by deposition on top of existing sediments. Animals preserved in the bottom layers are therefore older than the animals preserved in the shallower layers.
