This is the map of my alien planet's continents and I want to know if the environments are accurate.
The symbol at the top is the Arctic island. It's like Greenland and has some greenery or should I say yellowery but is mostly frozen and covered in snow. It is above the middle equator of the planet. The one in the middle of the equator and middle of the super continent is a jungle/forest. Do these normally happen in the middle of a continent? The one next to it is a savanna, and the one above it with the orange is a desert. And finally the one at the bottom-left of the continent is a swamp or marsh, and the other one on the left of the forest symbol is a grasslands.
Would these be accurate? and What would the bottom of the supercontinent where all the rivers meet be? I imagine the lower level being eroded by waves and frequent storms.
The pyramid-looking things are mountains and not pyramids.
The conditions of my super earth for help-The atmosphere of the planet has 30% oxygen (if this is too much then i will take it down to 25% to avoid global fires). Argon is 0.92% and nitrogen is around 65% and there's like 0.1 percent of other gases like carbon dioxide,methane and water vapor. The average temperature is between 59 and 49 degrees Fahrenheit. The average humidity is around 57% while the highest could be around 60° on a hot season, but it's not 60° the whole planet.
