Answer 4

That's a pretty good question, actually.  No one really knows, but what we do know is that there wasn't any land life and sea life wasn't much more than slime and microscopic stuff.  

Not really clear if continents were large land masses or a bunch of little microcontinents.  The air didn't have free oxygen, and neither did the ocean, (well, the middle pc is when the oceans became oxygenated so it changed a lot apparently during this period).

I suspect it was a pretty naked and rough place, maybe like mars but with a lot of water?  Or more like a cold and wet venus ?  (venus has the clouds, mars has the CO2 atmosphere-neither have the water)

Pretty well gotta use your imagination on this one-rainy days in CO2-rich air with no vegetation.  Sounds pretty harsh.  Not really a place I'd say "let's stop here" if I were a space alien.

Answer 5

Pretty much just bare rocks and water with a lot of algae floating around.

Answer 6

the Precambrian super-eon lasted about 4 billion years, from the very beginning of earth to about 500 million years ago. lot;s of things happened and earth changed dramatically several times during it:-)

you'd have to be more specific.
