deposition at transform boundaries accretion at convergent boundaries landslides at divergent boundaries meteorite impact at convergent boundaries
I gave my students this multiple choice question: The western coast of the United States has been increasing in size for millions of years. Which process has added material to the western coast of the United States?

Only one answer is correct among these 4 choices:
- deposition at transform boundaries
- accretion at convergent boundaries
- landslides at divergent boundaries
- meteorite impact at convergent boundaries

Could you tell me which one is correct?
