What do you think of contours, rivers, plates, etc? Geographical location?

If you look at the characteristics, just look directly. Rivers, highest points and residential areas are all written, and plates are not visible on topographic maps, so you need geological maps or structural maps.

Contour lines mean that the heights on the same line are equal.

You draw a straight line on the contour line and connect two points on the contour line. The height of these two points is the same.

There is also a contour line in this contour line, which is also crossed by this straight line. From the numerical value, you can know whether it is higher or lower than the contour line you are connected to.

If it is high, imagine that the middle of the ridge is high and the sides are low; Low in the middle and high on both sides, that is the valley.

Similarly, the terrain with dense contour lines is steep and changeable, while the terrain with sparse dispersion is slow.
