A geographical feature characterized by its massive size and sheer cliffs is a plateau, specifically a tableland or a mesa. Plateaus are elevated flatlands that rise sharply above the surrounding area, often due to volcanic activity or tectonic uplift. Their cliffs can be steep, presenting a dramatic contrast with the adjoining valleys. Plateaus are significant for agriculture and settlements due to their fertile soils and access to natural resources. They also serve as ecological regions, hosting distinct flora and fauna adapted to their unique conditions.
