How are isotopes used in scientific research?
Isotopes are used to determine the age of rock.
Can scientist use the isotope c-14 to date granite?
Yes because they look at the ammount of radioactive decay and they can determine the age of the granite. As the radioactive isotope decreases the non radioactive element increases. The less radioactive decay ammount there is the older it is.
. Describe in a few sentences how scientists use radioactivity to determine the age of a rock.?
Scientists use radioactivity to determine the age of a rock through a process called radiometric dating. They measure the amount of radioactive isotopes present in the rock and the rate at which they decay into stable isotopes. By comparing the ratio of parent isotope to daughter isotope, scientists can calculate the age of the rock based on the known half-life of the radioactive isotope.
Which isotope can be used as a tracer to study the age of organic material?
Carbon-14
What is dating rocks?
Dating rocks is when the radioactive isotope, carbon-14 is used to determine the age of fossilised rocks. Carbon-14 is present in the air, and is absorbed by plants during photosynthesis. When animals/people eat plant matter, they absorb the carbon-14 from the plants into their bodies. It has a half-life of 5730 years and so the mass of C14 remaining in a fossilised rock can be used to determine the age of the rock.

How can bone remodeling determine age?
Bone remodeling can provide information about someone's age through the process of continuous bone turnover. As people age, their bones undergo remodeling, where old bone is broken down and new bone is formed. By studying the rate of bone remodeling and the balance between bone formation and resorption, researchers can infer an individual's age. Additionally, changes in bone density, structure, and composition can also indicate age-related bone remodeling patterns.
How is radioactive decay used to determine the absolute age a rocks?
The basic idea is to measure the amount of the radioactive isotope, and of one or more of its decay products. The older the rock, the larger the percentage of the original isotope that decayed - so the ratio between the original isotope and the decay product changes over time.
Why is a uranium isotope often used rather than 14C in radiometric dating to determine the age of earth?
The isotope carbon 14 is used only for organic materials (or objects contaminated with organic materials); also carbon 14 dating is applicable only to short periods of time.

What is the use of measuring the activity of a radioactive isotope in a sample to determine its age?
radioactive dating
What was the use of bone hook in stone age?
In the Stone age, bone hooks were used for fishing.
Which of the following terms describe the process that is used to determine the age of an object by measuring the amount of a certain radioisotope remaining in that object?
The general term is "radiometric dating. If the isotope is carbon, then it is "carbon dating"
Which isotope can be used as a tracer to study the age of organic material?
Carbon-14
Explain how radiometric dating is used to estimate absolute age?
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
How can bones determine age?
Bone remodeling can help determine age because when a person is dead their bones shows every little mark , which on most bones displays a pattern called lamellar.
