The age of our planet i.e. Earth is

Question

Accepted Answer

The age of our planet i.e. Earth is more than 3600 million years because:

*   **Option 1 is correct:** Scientific evidence, primarily based on radiometric dating of meteorites and the oldest Earth and lunar samples, indicates that the Earth is approximately 4.54 ± 0.05 billion years old. This translates to 4540 million years. Therefore, "More than 3600 million years" accurately reflects the Earth's age, making it the correct option.

*   **Option 2 is incorrect:** 2600 million years is significantly younger than the established age of the Earth. Radiometric dating of ancient rocks and meteorites consistently points to a much older age.

*   **Option 3 is incorrect:** 1600 million years is also far too young to represent the age of the Earth. The Earth was already a well-formed planet with geological processes occurring long before this time.

*   **Option 4 is incorrect:** 600 million years is a gross underestimation of the Earth's age. This timeframe only covers a relatively recent portion of Earth's history, specifically the Phanerozoic Eon, which is characterized by the rapid diversification of multicellular life. The Earth existed for billions of years before this period.
