The absolute age of a rock is the approximate number of years ago that the rock formed. The absolute age of an igneous rock can best be determined by?
It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
What method do geologists to determine the absolute age of a rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
How does a geologist determine absolute age?
Geologists determine absolute age by using radiometric dating techniques that involve measuring the decay of radioactive isotopes in rocks or minerals. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, geologists can calculate the absolute age of the rock formation. This method provides a numerical age in years for the rock layer or mineral.
Absolute dating is best performed on rocks formed?
Absolute dating is best performed on igneous rocks formed from volcanic activity, as they contain radioactive elements that decay at a known rate and can be used to determine the rock's age. Sedimentary rocks are typically dated using the fossils contained within them, allowing for a relative dating technique rather than absolute dating.
What evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.

Why is it difficult to determine the absolute age of a rock?
It is difficult to determine the absolute age of a sedimentary rock because sedimentary rocks are made up of diverse particles that are all different ages. As a result radioactive dating can only determine the age of the particles, not the whole rock.

The absolute age of a rock is the approximate number of years ago that the rock formed The absolute age of an igneous rock can best be determined by?
The absolute age of an igneous rock can best be determined by radiometric dating methods, such as uranium-lead dating or potassium-argon dating. These methods rely on the natural decay of radioactive isotopes in the rock to calculate the time elapsed since the rock formed.
What property of radioactive elements make useful for determining absolute age?
Igneous rock. If you are in FIS you know me. O.K.

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.
What property of radioactive elements make them useful for determining absolute age?
The property of radioactive decay is what makes radioactive elements useful for determining absolute age. By measuring the amount of parent and daughter isotopes in a sample, scientists can calculate the age of the material based on the known half-life of the radioactive element.
How is the absolute age of a rock determined?
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
Why can't scientist use carbon to determine the age of an igneous rock?
Largely because igneous rock doesn't contain any carbon; any carbon would be vaporised in the heat of molten rock. Uranium is more commonly used to date igneous rocks.
