Answer:
a. A convergent boundary is where plates come together and a divergent boundary is where they move apart from each other.
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.
The language is the most basic mean of understanding and collaboration between the people. If there's two or more groups of people that speak different languages, than automatically they will only communicate and collaborate with people that speak the same language, while avoiding the people that speak another language as they will not be able to understand each other.
This can be a very big reason for division between the people. This usually means that there will either be a country that is divided and functions with two or more confederate states, or more likely it will lead to separatist movements and creating two or more nations. The borders will most likely be set in accordance to the areas where certain language is spoken.
