The meteoroids present in the space some times enter the Earth's atmosphere due to the _____pull of the Earth.

Options

A. gravitational
B. frictional
C. both a and b
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the reason why meteoroids enter the Earth's atmosphere. It provides a blank space that needs to be filled with the correct term.

2. **Identifying Key Terms**: The key term in the question is "pull of the Earth." This suggests that we are looking for a force that acts on the meteoroids.

3. **Recalling Relevant Concepts**: In physics, the force that attracts objects towards the Earth is known as gravitational force or gravitational pull. This force acts on all objects with mass.

4. **Applying the Concept**: Meteoroids are small rocky or metallic bodies in space. When they come close to Earth, they are influenced by the Earth's gravitational pull, which attracts them towards the planet.

5. **Concluding the Answer**: Therefore, the correct term to fill in the blank is "gravitational pull." This explains why meteoroids can enter the Earth's atmosphere.

6. **Final Answer**: The meteoroids present in space sometimes enter the Earth's atmosphere due to the **gravitational pull** of the Earth.
