Which isotope is useful for dating wood and charcoal that is less than 60 000 years old?
Carbon-14 (C-14) is the isotope commonly used for dating wood and charcoal that is less than 60,000 years old. It is a radioactive isotope of carbon that decays over time, allowing scientists to measure the age of organic materials through radiocarbon dating. This method is effective for dating samples from the late Pleistocene and Holocene epochs.

What radioactive isotope has a half-life closet to 5000 years?
The radioactive isotope with a half-life closest to 5000 years is Carbon-14 (C-14). It has a half-life of approximately 5730 years, making it useful for dating organic materials in archaeology and geology. C-14 is produced in the atmosphere and is absorbed by living organisms, allowing for the determination of the age of remains after death.
What isotope is best for dating very old rocks?
Uranium-lead dating is often used for dating very old rocks, as it has a long half-life of about 4.5 billion years. This allows for dating rocks that are millions to billions of years old with good accuracy.
What isotope is used to date rocks'?
The isotope commonly used to date rocks is Uranium-238 (U-238). It decays into Lead-206 over a predictable timescale, allowing geologists to determine the age of igneous and metamorphic rocks through a process known as uranium-lead dating. This method is particularly useful for dating rocks that are millions to billions of years old. Other isotopes, like Potassium-40 and Rubidium-87, are also used for dating different types of rocks.
What is the similarity of radioactive isotope and radioactive dating?
Both radioactive isotopes and radioactive dating rely on the process of radioactive decay. Radioactive isotopes decay at a known rate, allowing scientists to measure the passage of time based on the amount of decay that has occurred. Radioactive dating uses this decay process to determine the age of rocks and fossils.
How do you find the half life in carbon dating?
You do not find the half life in carbon dating. The half lives of carbon isotopes are derived by studying their radioactive decay. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.
Which isotope is useful for dating wood and charcoal that is less than 75000 years old?
carbon- 14
Which isotope is useful for dating wood and charcoal that is less than about 75000 years old?
Carbon-14 is the isotope commonly used for dating wood and charcoal less than about 75,000 years old. This isotope is useful because plants take in carbon-14 while they are alive, and it decays at a known rate after the plant dies, allowing for accurate dating.
The characteristic of the radioactive isotope uranium-238 that makes this isotope useful for accurately dating the age of a rock is the isotope's BLANK?
The characteristic of the uranium-238 isotope that makes it useful for dating rocks is its long half-life of about 4.5 billion years. This allows for accurate dating of rocks that are billions of years old.
What isotope is used to date plants and animals that lived during the last 10 000 years?
The primary dating isotope is carbon-14
Why is carbon dating not useful for determining the age of human artifacts that are 100000 years old?
Carbon dating is limited to around 50,000 years due to the half-life of the carbon-14 isotope. Once an artifact exceeds this range, there is not enough carbon-14 left to accurately measure its age. Other dating methods, such as uranium-lead dating, are used for older artifacts.
What radioactive isotope has a half-life closet to 5000 years?
The radioactive isotope with a half-life closest to 5000 years is Carbon-14 (C-14). It has a half-life of approximately 5730 years, making it useful for dating organic materials in archaeology and geology. C-14 is produced in the atmosphere and is absorbed by living organisms, allowing for the determination of the age of remains after death.
Carbon 14 is useful for dating fossils that are?
Carbon 14 is useful for dating organic remains less than 60-70,000 years old. It is not useful for fossils as the vast majority are much older than that.
Carbon 14 dating technique can be used to date the most ancient rocks on Earth. True or False?
False. The half life of Carbon 14, which is a radioactive isotope and unstable, is only 5,730 years. Carbon 14 dating techniques are only useful up to 60,000 years and therefore are mainly used by archaeologists and not very much by geologists.

What is a example of a radiochemical dating?
An example of radiochemical dating is carbon-14 dating, which is used to determine the age of organic materials. It measures the ratio of carbon-14, a radioactive isotope, to carbon-12 in a sample. As carbon-14 decays at a known rate (its half-life is about 5,730 years), scientists can estimate how long it has been since the organism died. This method is particularly useful for dating artifacts, fossils, and other biological remains up to about 50,000 years old.
How useful is isotopes for dating bones a million years ago?
Just for knowing its origin
