Question

How are the movement of plates at divergent boundaries and at transform boundaries similar?

Answer 1

They both have earthquakes and involve two tectonic plates.

Explanation:

Divergent boundaries are where two tectonic plates are moving away from each other, allowing the mantle to flow up and create new lithosphere. There are volcanic eruptions, as well as very weak earthquakes.

Transform boundaries are where two tectonic plates are moving past each other, and they don't create or destroy the lithosphere. There are usually strong earthquakes.

So the only similarity I see between the two is that they have earthquakes and involve two tectonic plates.
