What are the three types of plate boundaries and how do they move relative to each other?

Convergent, Divergent, Transform Boundaries are three plate boundaries.

Explanation:

The boundary where the two separate plates push into each other forms a Convergent boundary. Group of volcanoes are formed in parallel line to the trench because of this.  

When two plates move in an opposite from each other forms a Divergent boundary. When two plates pass each other grinding one another, it results in transform boundaries. This does not result in the mountain formation whereas the halting motion of plates results in Earthquakes.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
