This is fitting because tectonic plates are the massive pieces of Earth's lithosphere (the rigid outer layer) that move and interact, essentially "building" and "remodeling" the planet's surface over geological time.
The term "tectonic" was first used in the 19th century to describe the forces that shape the Earth's crust. It wasn't until the mid-20th century that the theory of plate tectonics was developed and widely accepted, explaining how these massive "building blocks" move and interact.
