What are the first and last steps of the scientific method
State question or problem, and conclusion
List the 3 plate boundaries, what they do and what they create
Divergent- moves away, creates new sea floor
Convergent- moves towards each other, creates volcano, mountains, trenches
Transform- Slide parallel next to each other, creates earthquakes
