Scientists can use carbon dating to determine the age of a fossil.

What do scientists estimate earths age to be?
Scientists estimate the age of Earth to be around 4.5 billion years old. This estimate is based on the analysis of radiometric dating of rocks and meteorites.
What do scientists use to calculate age when a fossil is too old for carbon dating?
Scientists use techniques such as uranium-lead dating or potassium-argon dating to determine the age of fossils that are too old for carbon dating. These methods rely on the radioactive decay of specific isotopes within the rocks surrounding the fossil to estimate its age.
What do scientists use to find a date on fossiles?
Scientists use radiometric dating methods to determine the age of fossils. This technique relies on the decay of radioactive isotopes within the fossil to estimate its age. By measuring the ratio of parent and daughter isotopes in a fossil sample, researchers can calculate how long ago the organism lived.
How do scientists determine age?
by seeing what levels the fossil go to
How old do scientists think the universe?
They estimate the age of the Universe in more than 12 billion years.
What is the process of how a scientist can estimate the age of fossil?
carbon dating
How do scientists tell the approimate age of mountains?
Scientists can determine the approximate age of mountains by studying the rock layers within them. By analyzing the composition, structure, and fossil evidence in the rocks, as well as using techniques like radiometric dating, scientists can estimate the age of the mountain and when it was formed. Additionally, studying the erosion patterns and surrounding geological features can provide clues about the age of a mountain.
What does relative dating provide for the age of a layer or fossil?
Relative dating provides an estimate of the age of a layer or fossil in relation to other layers or fossils. It does not provide an exact age in years, but instead helps determine whether something is older or younger than something else based on the order in which they are found.
What is the age of the oldest fossil on record?
The age of the oldest fossil on record is about 3.5 billion years old.
What is the relative age of a fossil that can be determined by comparing it to an index fossil is called?
The relative age of a fossil that can be determined by comparing it to an index fossil is called biostratigraphic dating. This method relies on the known age range of the index fossil to estimate the relative age of the fossil being studied.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
What is the age of earth accepted by most scientists?
Most scientists estimate the age of Earth to be around 4.5 billion years old, based on radiometric dating of meteorites and rocks from the planet's surface. This age is determined by measuring the decay of radioactive isotopes in these materials.
