|
Fossils are not affected by weathering and erosion.
|
|
|
Fossils stopped being formed thousands of years ago.
|
|
|
Fossils are usually located near ancient volcanoes and fault lines.
|
|
|
Fossils found in deeper layers are older than those found in upper layers.

Detailed explanation-1: -It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers. Therefore, some discovered fossils are able to be dated according to the strata, a distinct layer of rock, that they are found in.
Detailed explanation-2: -Sedimentary rocks are formed particle by particle and bed by bed, and the layers are piled one on top of the other. Thus, in any sequence of layered rocks, a given bed must be older than any bed on top of it.
Detailed explanation-3: -The deeper a fossil is found, the older the rock layer it is found in.
Detailed explanation-4: -This is called the Law of Superposition in geology. Students in the above images, you see that older layers are on the bottom and therefore the animal fossils found in those older layers are therefore older animals. More recent organisms are found on the top layers.
Detailed explanation-5: -The oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Fossils are once-living organisms that have been turned into rock, in which the shape or form of the organism can still be seen.
