How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
How do scientists date fossils and artifacts?
Dating fossils and artifacts are easy. Scientist can look and tell how old the fossils by how many layers is under it.
Fossils that appear all over the world in certain rock layers are what?
Index fossils :)
Why is the seaside a good place to look for fossils?
The seaside is a good place to look for fossils because it often contains exposed layers of sedimentary rock that are rich in fossils. The constant erosion from the waves can also help to uncover new fossils that may have been buried. Additionally, marine environments are known to have a high abundance and diversity of fossilized marine organisms.
Describe what happens at a transfrom boundary-?
The transform boundary is also known as the transform fault. This type of boundary is commonly found in deep ocean floors and are typically involved in movement which aids in relieving tension in the layers of the earth.

The atmospheres layers contains what?
The atmosphere layers contain huge abundance of air. These are divided into 4 layers.

Are older fossils found in higher layers of earth or lower layers?

What are index fossils and how are they used to determine the absolute age of sedimentary rock?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.

Why are index fossils useful for figure out the age of a set of disturbed rock layers?
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
What type of rocks form in layers and have fossils in them?
sedimentary
