Question

FORMATION OF FIRST CRUST: WHAT HAPPEND DURING THE EVENT WHICH TECTONIC PLATES WERE INVOLVED HOW IT CHANGED EARTHS SURFACE. PUT IT ALL IN 2-3 SENTENCES COMBINED

Answer 1

The first solid crust formed as the primordial magma ocean cooled and partially crystallized, producing dense basaltic crust and locally buoyant, silica‑rich proto‑continents through melting, volcanism and impacts. Modern plate tectonics likely did not exist yet—early tectonics involved a stagnant lid and small, short‑lived proto‑plates and mantle overturns whose collisions and recycling gradually stabilized crust and created the first continents, transforming Earth from a molten surface to one with solid land, shallow oceans, and new erosion and geochemical cycles.
