How to identify five basic landforms on the terrain?

First of all, the five basic landforms refer to plains, plateaus, hills, basins and mountains.

The map is a plane, how to represent the uneven three-dimensional terrain? There are several representations such as layered color topographic map (color map), shading map (color map), contour (depth) topographic map and topographic profile map.

Layered color topographic map: green represents the plain, blue represents the ocean, yellow and brown represent the plateau and mountain, and the depth of color indicates the height.

Shading map: a photo equivalent to a topographic map, which is represented by shading color. This is easy to understand.

Contour topographic map: plains and plateaus are sparse contours, which are distinguished by height values; The contour line of the mountain is closed and pulse-shaped; There are many small closed circles in the contour line of hilly terrain, and the contour data are generally within 1000 meters; There are dense contours around the basin and sparse contours in the middle.

Profile: a topographic map that cuts the terrain vertically and reflects the height difference.

The distribution characteristics and laws of topography should be analyzed in combination with regional geography (world geography & China geography), such as plateaus, basins and mountains in the west of China, plains in the east and hills in the southeast.

(Attach a simple picture:)

Contour topographic map is a common figure in geoscience examination, which should be grasped emphatically. It is the carrier in geography and is linked with climate, agricultural planting and engineering construction through contour topographic map.
