where rivers form where tectonic plates meet where oceans are deepest where land and water meet
I gave my students this multiple choice question: Where are the active volcanoes most likely to be found?

Only one answer is correct among these 4 choices:
- where rivers form
- where tectonic plates meet
- where oceans are deepest
- where land and water meet

Could you tell me which one is correct?

where tectonic plates meet
