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.
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers scientists can learn what?
I.which types of organisms were more common during various time periods.II.how species have evolved over time.III.the relative age of different species. there it is
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
An understanding of which of these best enabled scientists to determine the approximate ages of fossils?
Radioactivity
What is examined to do relative dating?
The position of fossils in sedimentary rock layers.
How can scientists determine the relative age of rocks and fossils an area?

What two things did 19th century scientists do to determine the relative age of sedimentary rock all over the world?
They studied fossils and applied the principle that old layers of rock are below young layers! -

Fossils that can be used to establish relative dates are most likely to be found in?
sedimentary rocks.
Can fossils be used to determine the relative ages of rocks layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
