    Honestly, by the numbers, Earth is mostly an ocean/forest planet with some desert. Desert and ice planets are believable, too, given those are more temperature-based, and city planets seem like they’d be inevitable in a sci-fi setting just due to population sizes.

      By the numbers I think it’s an ocean planet with 71% coverage. Of the land, it’s actually pretty evenly split 1/3 forest, 1/3 desert, 1/3 grass or shrubland.

      Given what we know of the Earth’s own history, forest planets, ice planets, and desert planets are all possible and the Earth has been each in different geologic times. Although in every case there will be pockets of other biomes that are very large on a human scale. A single France-sized forest would be massive to a human explorer, even if the rest of the planet is ocean and ice.
