A modern controversy by some maverick, so-called historians wishes to prove that the Great Pyramid of Egypt was built more than
10,000 years ago instead of the generally understood age of 5600 years ago. They propose to date the Cretaceous limestone used to construct the pyramid by using Carbon-14. Will they be successful in proving the pyramid was built 10,000 years ago? If not, why not? HINT: C-14 has a half-life of 5730 years and a maximum utility of 50,000 to 100,000 years.
The method of carbon dating is used to measure the age of artifacts. This has made the technique very important in archaeological investigations.
The method of carbon dating is useful for determining the age of any material of plant or animal origin. However, the material fall within a specified age limit for this method to be successfully applied to it.
Since Carbon-14 dating technique has a maximum utility of 50,000 to 100,000 years and a half life of 5730 years , then they will be successful if they use Carbon-14 dating in the study.
Explination:The moon is tidally locked to the Earth because it rotates in exactly the same time as it takes to orbit the Earth. That is also why we only see one side of the moon.
Earth’s crust is made up of tectonic plates and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep.
