Question

What are fossil ? how is age of fossil determined?

Answer 1

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it. fossils are. the remains or impression of a prehistoric plant or animal embedded in rock and preserved in petrified form.

Answer 2

HI

✨ Fossils : the preserved traces of organisms which lived in the past.

⭐️ Ways to determine the age of fossils:

▶️ From the depth of the layer of the earth in which the fossils are found. Fossils found closer to the surface are more recent than those found deeper.

▶️ By detecting the ratios of different isotopes of the same element in the fossil material.
