<u>Answer:</u>
All of the above mentioned options can be used by scientists to date the sediment layer they are found in.
<u>Explanation:</u>
- Rock fossils, animal fossils, etc.found in the sediment layer can be used to determine the age of the sediment based on the period of the existence of that animal or the period of formation of the rock.
- Tree rings clearly exhibit the age of the tree. Hence, a sediment layer with the evidence of tree rings can tell the age of the sediment layer.
- An amalgamation of the data obtained from the animal growth rings and the period of existence of that specific animal species can be used to calculate the age of the sediment.
- The intensity of radioactivity left in the isotopes clarifies how old the isotope is.
- The age of mineral elements can be determined exactly with the help of processes like Potassium-Argon dating, Uranium-Lead dating, etc.
- Thus it would be easy to determine the age of the sediment layer containing mineral elements.
