Options

A. 4600
B. 3000-4000
C. 2
D. 10000

Answer

To determine the age of the Earth in million years, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Age of Earth**: The age of the Earth is estimated to be about 4.6 billion years. This is a widely accepted scientific estimate based on various forms of evidence, including radiometric dating of the oldest rocks and meteorites.

2. **Convert Billion Years to Million Years**: Since the question asks for the age in million years, we need to convert billion years to million years.
- 1 billion is equal to 1000 million.
- Therefore, to convert 4.6 billion years to million years, we multiply by 1000.

3. **Perform the Calculation**:
- \( 4.6 \, \text{billion years} \times 1000 = 4600 \, \text{million years} \).

4. **Conclusion**: The approximate age of the Earth is 4600 million years.

5. **Select the Correct Option**: Based on the calculations, the correct answer to the question is option A, which states that the age of the Earth is approximately 4600 million years.

### Final Answer:
The age of the Earth in million years is approximately **4600 million years**.
