the age of the earth can be estimated in many ways. which statement below is most accurate (remember that uniformitarian calculations involve looking at the thickness and type of sedimentary rocks, and similar things, but do not include radiometric dating or counting of annual layers)? group of answer choices uniformitarian calculations show that the earth is more than about 100 million years old, and radiometric techniques tell us how much older. uniformitarian calculations show that the earth is more than about 1 billion years old. uniformitarian calculations show that the earth is about 100 million years old. uniformitarian calculations show that the earth is 4.6 billion years old.



Answer :

The correct answer is uniformitarian calculations show that the earth is more than about 1 billion years old. uniformitarian calculations show that the earth is about 100 million years old. uniformitarian calculations show that the earth is 4.6 billion years old.

Scientists use a sample of the item they wish to date to determine how much parent isotope and daughter isotope are present. This method is known as radiometric dating. They can establish the age of the substance from this ratio. Can sediment thicknesses be used to accurately estimate the Earth's age? No. Rather than the strata themselves, unconformities between layers indicate the majority of Earth's history. Geology and tree ring research demonstrate that the Earth is just 5,000 years old and not any older. The longest record, which spans more than 100,000 years, is supported by several tests and indicates that certain ice cores have stably kept yearly layers.
