Fossils up to 75,000 years old can be dated with Carbon-14.

Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.

I'm stuck on this problem

Veseljchak [2.6K]

Answer:

Dear people in Westfield,

your pipes contain rust because of a chemical reaction on the iron you use.The problem could be fixed by using strong plastic pipes as that takes a long time to degrade.The rust is produced when water and air mix with the iron.it takes time for the pipe to rust but that is the problem

as I said before,try using plastic pipes that are resistant to pressure.you could get them at home Depot or other pipe production company's.

Sincerely,

random kid

A fossil can be studied to learn __________.

Fudgin [204]

I think the best answer is letter b. which is all of these. By studying fossils, a scientist can determine what organism is found. The scientist also can determine the age of the fossil but it can be recognized as a fossil if it was older than 5,000 years. And lastly, fossils can illustrate the changes of environment, climate and evolutionary patterns of our world.
