Short answer: No — the formation of the Earth itself was not a convergent-plate-boundary process. Plate boundaries are processes that operate on a finished planet; Earth formed earlier by accretion and differentiation.
A bit more detail and the relevant boundaries afterward:
- How Earth formed: Earth grew from dust and planetesimals in the solar nebula (accretion), probably experienced a giant impact that formed the Moon, and then differentiated into core, mantle and crust. This happened ~4.6–4.4 billion years ago and is not described by plate-tectonic boundary types.
- When plate tectonics started (debated, maybe 3.8–3.0+ Ga), different boundary types then produced and modified crust:
- Divergent boundaries (mid‑ocean ridges) create new oceanic crust by upwelling magma.
- Convergent boundaries (subduction zones and continental collisions) recycle oceanic crust and are the main way continental crust and mountain belts form (e.g., island arcs, the Andes, Himalaya).
- Transform boundaries slide plates past one another and don’t create/destroy much crust (e.g., San Andreas Fault).
If you meant a specific feature (the continents, mountains, the Moon, etc.), tell me which and I’ll say which tectonic or non‑tectonic process made it.
