UUHHHMMM
are we talking fantasy or SF here?
lately a lot of geomorphological research is centered on the link between
largescale geophysical phenomena and geomorphology.
If you want to build a world consistent with current views on our planet,then you have your work cut out for you!
remember,e.g. if you describe seasons,the planet has to have an axial tilt.
Tides imply a satellite,etc.Vegetation,ice cover etc.imply heat sources and sinks,and influence planetary albedo.Strong air movements(storms) imply strong differential heating,
et a lot of
cetera.
Hope I haven't scared you,BTW
