What was the earth covered with when it first formed?

Answer 1

Earth accumulated from an assortment of rocks, icy bodies, dust and general rubble, the general ejecta from a supernova, combined with general space junk. When it became sufficiently large, compression due to gravitydeveloped, Among these were of course some radioactive ones, and the core became warm due to the radioactivity and gravitational pressure, eventually melting

and the heavier elements sank to the core.

Once melting was well under way, molten material ejected to the surface as volcanoes, emitting methane and CO2. There was little oxygen present at this stage.

The surface was not completely red hot as we know from radiometric dating that there were some zircon crystals present at this time.
