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.
Sand can be trucked in from other sources and filtered for sediments to eventually make way into the air and water. They can also build seawalls, revetments, and jetties along the shoreline. :)
The correct answer is - C. hot spots in the mantle.
The Hawaiian Islands are a volcanic islands. They are lying above a hot spot. The hot spot volcanoes, unlike the other ones, are far away from the boundaries of the tectonic plates and they are emerging on places were there's hot spots. These hot spots manage to penetrate through the crust and get the magma from the mantle up to the surface and create volcanic islands in meantime.
