In what way is the use of radioactive dating more beneficial than the other techniques?
Radioactive dating is beneficial because it provides an absolute age for rocks and fossils based on the decay of radioactive isotopes. This method is more precise than other dating techniques and can accurately determine the age of objects that are millions or billions of years old. Additionally, radioactive dating can be used to study the Earth's history, evolution of life, and past environmental changes.
What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.
Why radioactive decay to date fossils and artifacts?
Radioactive decay is used to date fossils and artifacts because certain radioactive isotopes have predictable rates of decay over time. By measuring the amount of remaining radioactive isotopes in a fossil or artifact, scientists can estimate how long it has been since the material was formed. This method is known as radiometric dating and provides a way to determine the age of objects that are thousands to billions of years old.
What of the use of isotopes in archeology?
One would use radioactive isotopes as to measure decay rates in an ancient piece (e.g. rock) to estimate its age. e.g. carbon dating
Is it true that radioactive dating means putting everything in proper sequence?
No. It means finding out the date something was created or died or placed by comparing the amount of certain radioactive isotopes to those expected of an original object before death or placement.
What does a radioactive dating estimate about the earth's formation with isotopes of uranium and thorium?
Radioactive dating estimate the age of rocks.
What Does radioactive dating with isotopes of uranium and thorium provide an estimate of the beginning middle or end of the period of Earth's formation?
The limit of this measurement is 500 000 years.
How Does radioactive dating with isotopes of uranium and thorium provide an estimate of the beginning middle or end of the period of Earth's formation?
The upper limit of uranium-thorium-230 dating is 500 000 years.
How Does radioactive dating with isotopes of uranium and thorium provide an estimate of the beginning middle and end of the period of earth formation?
The upper limit of uranium-thorium-230 dating is 500 000 years.
What way is the use of radioactive dating more beneficial than the other techniques?
Radioactive dating can be used to estimate the absolute age of an object.
What would be the most appropriate estimate for 54 out of 99?
15
When is it appropriate to estimate an answer?
In a school lunch serving or a when going to the groceries store
What is the most appropriate unit of measure that can be used to estimate the area of a country?
Metric
When you make an estimate within a graph what are you making?
You are making an estimate. You are making an assumption that the model is appropriate and that it is valid for the required values of the independent variables.
How does radioactivity allow us to estimate the Earth?
Radioactive or radiometric dating allows us to estimate the Earth's age by giving us the actual age of rock within a range of several million years. Radiometric dating is based on the scientific law of radioactive decay and the half-life of radioactive elements. Uranium and some other elements decay into lead over time at a specific rate. Knowing the content of these elements in the makeup of a rock allows its age to be calculated. Currently, the oldest rocks of Earth origin are estimated to be over 4 billion years old.
When is estimating an appropriate course of action?
An estimate may be appropriate when a more precise calculation is not possible or would require too much in time or other resources for the value of the answer that might be obtained. When doing school work, however, it is only appropriate to estimate an answer when doing so is part of the process being taught at the time.
What is the most appropriate unit of measure to estimate the length of a golf club?
You would use inches.
