A ball of dust, ice, and rock was pulled together by gravity.
Reason: accretion of dust and planetesimals built the proto‑Earth first; subsequent collisions generated heat that melted and formed the core, followed by cooling and solidification of the crust and mantle, and later the young Sun’s strong winds could strip away a primordial atmosphere.
