Planation is a geomorphological process which creates nearly flat surfaces by fluvial (river), aeolian (wind) and marine processes. The process is erosional and takes millions of years, and its legacy from the tertiary period (65-2Ma) is present in many of today's landscapes. It has been studied since the 1890s but many fundamental questions remain about this process.
