How can fossils be used to date rocks?
Geologists look for index fossils in the sedimentary rock to help determine its age. Index fossils are of organisms that were widespread and only existed during a specific slice of geologic time. Finding an index fossil in a rock means that the rock dates to that specific slice of time.
What type of rock is most useful historical geologists?
Geologists love sedimentary rock because the fossils give a quick reference to their date of formation and environment of deposition.
How do geologists use index fossils to determine rock age?
Index fossils, also known as zone or guide fossils, help date strata and sediment to determine the age of entrapment. The best index fossils are those that were abundant , common, and short lived.
Is this question true or false to study earths interior geologists often rely on indirect methods such as evidence from fossils?
no they use seismic waves
What do geologists look for?
Geologist look for rocks that have been in the earth.Geo in in geologist means earth.Geologist also may look for fossils from dinosaurs millions of years ago.

How do geologists use the column?
Geologists use the geologic column to classify layers of rocks and fossils that make up the Earth's crust.

What are index and what do geologists learn from them?
Index fossils are very important to geologists because they identify geological. The fossil snail is a particularly difficult animal to study.
Who dates fossils?
Fossils can be dated within a broad range by studied amateurs, geologists, and paleontologists. Absolute dating within a narrow time range is the domain of paleontologists and some geologists, scientists with access to specific information, knowledge, and equipment.
How do geologist us the geologic column?
To help them interpret rock sequence .

What do scientists use index fossils for?
Geologists use index fossils to define and identify geologic periods.
What type of rock is most useful historical geologists?
Geologists love sedimentary rock because the fossils give a quick reference to their date of formation and environment of deposition.
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
How are index fossils used by uniformitarian geologists?
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
