You will need to narrow or broaden your research question to make sure you have enough supporting information to write an essay that fits with the requirements. Make sure you understand the assignment's guidelines and talk to your professor if you are unsure!
Example of applying these strategies to the topic of orbital debris and narrowing it down to something more manageable:
Now: What is the impact of small orbital debris on Earth's ecological safety?
Once you start testing your research question, you might find that you narrowed it down too much. If that’s the case, you can use opposite strategies or remove one component to broaden it.
Let your research question evolve naturally as you research.
