There is incredibly little variation in biomes on Uriti. The temperature ranges from 1105℃ to 1285℃ at the poles, with a maximum recorded temperature of 1673℃ along the planet's Equator. These temperatures are caused by the atmosphere trapping all the heat that enters, leaving none to escape and causing the surface of the planet to never cool down.
The entire planet is coated with lava, a fairly liquid form of it. This lava is capable of running as rivers and falls, erupting constantly out of volcanoes and seeping out of large cracks in the ground that extend down to the mantle.
