Recipe for Mountainous Single Biome Planets Start with a desert planet in a young solar system full of small rocky (non-ice) asteroids. Let the asteroids fall into the planet's gravity well to punctuate the planet's crust with craters and crater ridges. Keep the individual impacts down to a size that at most cracks the tectonic plates, not so big that they ...

I assumed sunken continents are what I marked with black dotted lines I marked hot currents in red and cold in blue, as far as I understand they should behave

I'm no oceanographer, but I would say that your submerged continents would affect ocean currents as if they weren't submerged. Surface currents generally run as deep a 400 meters, so it's entirely reasonable that your continents being around 3 meters below sea level would exert an effect on surface currents. Deep water currents would naturally be affected. ...

Trees are not a given. You could have a world whose only plants are grasses, or at least grasslike. Evolution on Earth favoured large woody structures in land plants but that doesn't necessarily mean that that is the only viable pathway. It is plausible that land plants could have maintained the frond like structure of the Caulerpa seaweeds which resemble ...

Recipe for Tropical Single Biome Planets Have a planet with a dam' good magnetic field and a thick atmosphere, around 20atm may be enough place it in orbit around a hot star, emitting in UV to soft-Xray at the peak of the black-body radiation spectrum - maybe a young white dwarf? You can put the planet way further than in the case of UV-Vis stars watch how ...

Short Answer: You are wrong about a moon tidally locked to its planet having eternal day on one side. If a planet is tidally locked to its star, one side of the planet will always face the star and have eternal day and great heat, while the other side will always face away from the star and have ternal night an d grat cold. Some older people might remember ...

One day lasting several earth-months Earth-days have little meaning on this Earth-like planet/moon, because it does not rotate. In fact, it does rotate, once per orbit, but this rotation is as slow as the orbit itself because of the tidal lock. Sundawn to sunset takes half the duration of the orbit. One orbit around the gas giant could take several of our ...
