Answer:
a. A convergent boundary is where plates come together and a divergent boundary is where they move apart from each other.
Step-by-step explanation:
The surface of the earth is made up of a series of different-sized tectonic plates. Over time, these plates move relative to one another, causing earthquakes and volcanic activities.
A convergent boundary is created when two plates come together. The force of this collision can push the edges of the plates into ocean or mountain floors, resulting in a series of volcano.
A divergent boundary on the other hand, is created when a plate moves apart from another. Usually, an earthquake will occur at this boundary and magma will erupt to the surface of the earth crust.
