map

First, the basic elements of the map

(1) Legend and notes: introduce the signs of each geographical thing. 2 direction: used to identify the direction; There are coordinates: n is north, s is south, e is east, and w is west; No coordinates: up north and down south, left west and right east; The direction is determined by the (north-south) latitude (east-west) network. ③ Scale: the ratio of the distance on the map to the actual distance. Expression: a. Numbers B. Words C. Line segments. Nature: large denominator, small scale, large scope and simple content; On the contrary, the opposite is true.

Second, the interpretation of topographic map

1, which is usually expressed by contour lines. The vertical distance above the altitude of a place on the ground is called altitude (absolute height). The vertical distance from one place to another is called relative height. Connecting points with the same depth in the ocean into lines on the map is called isobath. The denser the contour, the steeper the slope; The thinner the contour, the slower the slope. Five different forms of mountains: peaks, ridges, valleys, saddles and steep cliffs.

2. Types of topographic maps: contour topographic map, layered color topographic map and topographic profile map.

3. land topography: The ups and downs of the surface are called topography.

Topographic types: plains, plateaus, mountains, hills and basins. On topographic maps, altitude is used to indicate the ups and downs of the ground. Green represents plains, blue represents oceans, yellow represents alpine plateaus, and white represents glaciers.

4. Topographic features: the common feature of plains and plateaus is that the ground fluctuates slightly; The difference is that the plain has a low altitude, generally below 200 meters, while the plateau has a high altitude and steep edges. The same feature of mountains and hills is that the ground is rugged; The difference is that the mountains are relatively high, with an altitude of more than 500 meters, steep slopes and deep valleys, while the hills are relatively low, and the relative height is generally within 200 meters. Most of the basin is surrounded by mountains or plateaus, and the middle part is relatively low and flat.

5. Submarine topography: continental shelf: the natural extension of land to the ocean, with a gentle slope and a water depth of less than 200 meters. Continental slope: A steep slope in which the continental shelf inclines outward and the water depth increases sharply to several kilometers. Mid-ocean ridge: the place where the seabed was born in the ocean, where volcanic activity is relatively strong. Trench: the deepest part of the sea floor. The maximum water depth can reach more than 1 10,000 meters.

Third, get information from the map.

Only by applying what you have learned and choosing a map correctly according to the purpose of use can you get useful information in time and accurately.
