That would be false. The Ozone layer is what protects Earth from UV radiation. The Ozone is part of the Stratosphere.
Answer: Radiometric dating
Explanation: Radiometric dating is a procedure used to determine the age of elements such as rocks and fossils. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
Microorganisms that live in severe habitats, such as very
hot, acidic, or salty environments are called extremophiles, which are
bacteria, archaea and eukaryotes. They are the most successful organisms
because they can adapt in any environment. They can live in oceans, rivers,
soil, and even inside a human’s body.
