What are the five basic landforms in the world?

Five basic landforms: mountains, plateaus, plains, basins and hills. Plain: a relatively small land area below 200 meters above sea level. The plain is wide and flat with little fluctuation. For example, the North China Plain

Plateau: The elevation is generally above 1000 meters, with a vast territory and open terrain, and a relatively complete large uplift area bounded by obvious steep slopes. Such as the Qinghai-Tibet Plateau.

Mountain area: above 500 meters above sea level, with a relative height difference of more than 200 meters. For example, Changbai Mountain and Wuyishan Mountain.

Basin: high around and low in the middle. For example, the Sichuan Basin.

Plain: low altitude and flat ground; For example, the Yangtze River Delta Plain

Plateau: high altitude, flat ground and steep edge; For example, the altitude of the Qinghai-Tibet Plateau is above 1000 meters.
