-What are plate boundaries?
In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys.
-What types of boundaries are there?
There are three main types of plate boundaries:
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.
-What usually happens when each type of boundary moves?
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.
