Final answer:
Tectonic plates can separate at convergent boundaries and subduction zones, leading to various geological phenomena.
Step-by-step explanation:
Tectonic plates are large, rigid pieces of the Earth's lithosphere that fit together like a jigsaw puzzle. At convergent plate boundaries, tectonic plates collide and often result in either the formation of mountains (as in the case of the Himalayas) or subduction zones.
A subduction zone is formed when one tectonic plate is forced beneath another plate into the mantle. This process occurs at convergent boundaries where an oceanic plate collides with a continental plate. Subduction zones are often associated with volcanic activity and the formation of deep-sea trenches.
