The document summarizes the geography of Spain. Spain is located on the Iberian Peninsula in southwestern Europe, surrounded by the Cantabrian Sea, Atlantic Ocean, and Mediterranean Sea. The peninsula is dominated by a large central plateau surrounded by various mountain ranges. Spanish rivers are generally short with irregular flows that depend mainly on rainfall, though some have larger flows due to passing through mountainous areas with abundant rainfall, such as the long River Ebro fed by tributaries from the Pyrenees.
