(Q002) Which of the following was a component of the Earth's Hadean atmosphere?Group of answer choicesozoneoxygenironammonia

The Hadean atmosphere of Earth, which existed about 4.6 to 4.0 billion years ago, was likely composed of light elements, such as hydrogen and helium, and heavier elements and compounds, such as nitrogen, carbon dioxide, and water vapor. However, it did not contain a significant amount of oxygen or ozone, as these are products of life processes and the Hadean eon predates the existence of life. Iron is a solid element and would not have been a significant component of the atmosphere.

Therefore, out of the given options, ammonia is the most likely component of the Earth's Hadean atmosphere. This is because ammonia is a compound of nitrogen and hydrogen, two elements that were likely present in the Hadean atmosphere.
