Hi,
I'm not good enough to contribute answers yet, but I hope to entertain you with questions.
Practically all the Earth formation stuff I've read talks about the Earth being molton. That always seems strange to me. If I think of a space body without an atmosphere, I generally think of it being damm cold. If I think of a proto-earth gathering up rocks and dust thru aggregation, then I think of this space dust being freezing cold grains of sand.
I guess what I'm missing is a clearer picture of the dust cloud that was probably the origin of our planet. Was this dust cloud super hot? Where there molten bits of sand and iron floating around in space raining down on proto-earth? I dunno. I just think a huge dusty "asteroid" looking space body is easier to imagine than this fire and brimstone stuff. Sure, when the planet gets big enough, then the silicates etc will turn molten under the pressure from above. But maybe, there was always a dust crust on Earth as we vacuumed up everything in our near orbit.
Thanks for any help.
