Radiometric or Radio-active decay dating involves looking at certain radio-active isotopes in the rocks of the earth, such as potassium and argon. Certain Isotopes have a half life and decay into another isotope after a certain amount of years. Geochemists use these types of dating to determine the age of rocks and how long the crust has been forming and moving.
What else can I help you with?
What can radiometric dating tell us about the age of rock that law of superposition cannot?
Radiometric dating can give us the absolute age of the rock. Trace fossils and the Law of Superposition can only provide the relative age of the rock. Radiometric dating is far more specific in formation analysis.
What type of dating involves half-lives and can tell in which geologic period a rock was formed?
This is called absolute, isotopic, or radiometric dating.
What evidence is given to tell how old the moon is?
Using standard radiometric dating of rocks returned from the Moon by the Apollo missions.
Can use radiometric dating on all minerals to tell their absolute age?
You can't date all minerals using the radiometric dating method because not all minerals have radioactive isotopes. In addition, the parent and daughter isotopes must remain together in a rock to use them to determine the rock's age. Because sedimentary rocks contain fragments of many rocks that could be different ages, radiometric dating is less useful for dating sedimentary rock. This technique is primarily used to date igneous rocks.
How do you tell how old a fossil is by the rock layer?
You can determine the relative age of a fossil by looking at the position of the fossil in the rock layers. The closer a fossil is to the surface, the younger it is relative to fossils found deeper in the layers. To determine the absolute age of a fossil, scientists use radiometric dating techniques on the surrounding rocks to determine the age of the rock layer the fossil is found in.
What does radiometric dating tell geologist about some rocks and minerals?
their ages
When was Earth's discovery?
Earths discovery is when believed to when god made earth, with Adam and eve with it it was full of wildlife and things to help Adam and Eve through there journey. Scientificly it was discovered six thousand years ago. you will hear popular science say that it is 4.5 billion years old, but there is no way to tell because radiometric dating methods can only date back approx. one million years. over ninety percent of radiometric dating results agree with the theory that the earth is six thousand years old. also they have found tissue and marrow in some dino bones agreeing with this theory.
Can you tell the age of the earth from fossils?
no but you can tell the age of the fossil from the age of the rock around it, you cant tell the age of the earth from fossils is because animals with bones were didnt exist until later in the earth's "life"
How can fossils be used to determine the relative ages?
They are able to tell the order in which events occured, NOT how long ago they occured.Identify the order in whicih rock units formed(:rocks makes babys with apenis
What radiometric dating tell us?
Radiometric dating tells us the age of rocks and fossils by measuring the decay of radioactive elements in them. By analyzing the ratio of parent to daughter isotopes, scientists can determine how long it has been since the rock or fossil formed. This allows us to establish the age of Earth's material and uncover the timeline of geological and biological events.
How could you travel through the mantle?
It's impossible but many scientists and other smart people are working on it. we can tell whats under the earths crust by the vibrations produced through earthquakes ect
What is the difference between radioactive decay and radiometric dating?
It is the difference between sand running out of an hour glass and determining what time it is by how much sand is left. Radioactive decay happens at a steady rate. If you can determine how much of that radioactive isotope ought to have been in a sample at the start and you can measure how much is left, you can tell how much time has passed.
