Geology and terrain
A varied continental planet
Sel contains broad continental regions with contrasting climates, mountain systems and river basins. Its geography supports strongly separated environmental zones.
Climate and atmosphere
Regional climates rather than one global pattern
Climate changes from temperate and fertile regions to drier interiors and colder highlands. Distance, elevation and continental barriers shape local conditions.
Biosphere
Life divided by geography
The known biosphere includes farmland, forests, grasslands and freshwater environments. The wider ecology remains poorly described outside the best-mapped regions.
Habitats
River basins, highlands and enclosed regions
Settlements favour river valleys, fertile plains and defensible highland corridors. Mountain ranges and distance isolate populations and environments.
Open questions
A map with major blank spaces
The unexplored continents, full climate cycles and diversity of remote ecosystems are not yet known in enough detail for a global model.
