What are the elevations of the four plateaus?
The Qinghai-Tibet Plateau, with an average elevation of 4,000-5,000 meters, is known as the "roof of the world" and "roof of the world".
The altitude of Inner Mongolia Plateau is 1000~ 1400 meters, which is high in the south and low in the north, forming an east-west lowland in the north, and the lowest altitude drops to about 600 meters. There are intermittent dry erosion residual hills on the border between China and Mongolia, and the relative height is about 100 meters.
The Loess Plateau slopes from northwest to southeast, with an altitude of 800-3000m.
Yunnan-Guizhou Plateau: The western Yunnan-Guizhou Plateau is more than 2000 meters above sea level, and the plateau topography is obvious. The eastern Guizhou Plateau is undulating, with many mountains and few plateau areas. It is called "Mountain Source", with an altitude of 1000- 1500m.
Altitude is the vertical height above sea level. People use an average sea level as the starting surface of altitude. Altitude is defined as the vertical height above the average sea level. I.e. elevation or absolute elevation. ? The elevation of the ground point calculated by the average sea level is called elevation or absolute elevation. Mean sea level, also known as geoid. Due to the inhomogeneity of mass inside the earth, the gravity lines of all points on the earth's surface do not all point to the center of the sphere. In this way, the geoid perpendicular to the gravity line forms irregular surfaces everywhere. So all countries in the world have their own average sea level, that is, the geoid. Altitude provides convenience for people to accurately express the ups and downs of geographical things.
