### How would a geologist use absolute dating to determine the age?

How would a geologist use absolute dating to determine the age of sedimentary layers? A.by dating the age of several radioactive elements in a sedimentary rock layer Hope this helps! Did this page answer your question?

### How is the age of a sedimentary rock layer determined?

by dating the age of several radioactive elements in a sedimentary rock layer by dating the age of intrusions and extrusions near a sedimentary rock layer by comparing the relative ages of several sedimentary rock layers by identifying fossils in nearby intrusion and extrusions and determining their age

### How do geologists date rocks and fossils?

Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil? This page has been archived and is no longer updated Dating Rocks and Fossils Using Geologic Methods

### What method is used to determine the age of rocks?

This method uses the orientation of the Earths magnetic field, which has changed through time, to determine ages for fossils and rocks. Relative dating to determine the age of rocks and fossils

### How would a geologist use absolute dating?

an ancient volcanic rock an igneous rock A Woolly Mammoth Fossil How would a geologist use absolute dating to determine the age of sedimentary layers? by dating the age of several radioactive elements in a sedimentary rock layer by dating the age of intrusions and extrusions near a sedimentary rock layer

### How do geologists determine the age of rocks?

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.

### How do you find the absolute date of a rock?

Radiometric dating. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes.

### What determines the age of ancient fossils older than 50 000 years?

measures the number of unstable elements in ancient volcanic rocks determines the age of ancient fossils older than 50,000 years old dates the remains of organisms to determine when they died

### How do geologists determine the age of rocks?

Relative dating to determine the age of rocks and fossils Geologists have established a set of principles that can be applied to sedimentary and volcanic rocks that are exposed at the Earths surface to determine the relative ages of geological events preserved in the rock record.

### How do geologists date rocks and fossils?

Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil? This page has been archived and is no longer updated Dating Rocks and Fossils Using Geologic Methods

### How do you determine the age of an isotope?

The abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. This method is known as radiometric dating. Some commonly used dating methods are summarized in Table 1. The rate of decay for many radioactive isotopes has been measured and does not change over time.

### How can you tell how old a fossil is?

Second, it is possible to determine the numerical age for fossils or earth materials. Numerical ages estimate the date of a geological event and can sometimes reveal quite precisely when a fossil species existed in time. Third, magnetismin rocks can be used to estimate the age of a fossil site.
