Evidence from the analysis of zircon crystals suggests that the Earth

Question

Quizplus · Accepted Answer

Evidence from zircon crystals suggests that the Earth had cooled down enough to have liquid water on its surface within the first 100 million years after its formation. This indicates that the Earth may have been habitable in a relatively short period of time after its formation. Therefore, the best choice is D. Option A is not necessarily true as the presence of liquid water does not guarantee habitability. Option B is not supported by the evidence, as the presence of oxygen is not a requirement for habitability. Option C is incorrect as the Hadean Eon lasted until approximately 4 billion years ago, much earlier than the timeframe indicated by the evidence.
