How might zircons scientists study early earth?
zircons are the remains of billions and billions of cyanobacteria.
zircons may add more radioactive isotopes to radiometric dating techniques.
zircons show how the earth's crust formed.
zircons may hold evidence of early life and atmospheric composition.

The Earth crust formation show by Zircon helps scientists to study early Earth.

Option C

Zircon is a popular mineral which is formed of mainly zirconium sulphate crystals and are mainly blue in colour. Zirconium sulphate crystals are very old in nature, dating back to thousands of years. These minerals actually hold the chemicals that were formed back then.

This minerals can be studied to explain how were the landforms and chemical composition of earth crust back to thousands of years. Zircons can also hold some other radioactive elements which were radioactive back to thousands of years, but now they are normal.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
