The solution is the point of intersection between the lines on the graph. Identify this point and substitute the x and y values into both equations to see whether they produce two true statements.

convergent boundaries: where two plates are colliding. subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.

divergent boundaries – where two plates are moving apart.

transform boundaries – where plates slide passed each other.

explanation:

the correct answer is in fact b. spring tides are the highest, while neap tides are the lowest.
