Third, the map

1, the basic elements of a map (three elements of a map)

(1) scale

① Concept: the ratio of the distance on the map to the actual distance.

(2) Forms of expression: numbers, characters and line segments.

(2) Direction explanation:

① General plan: face the map from north to south, from left to west, and from right to east.

② Map with beacon: According to the direction, the beacon arrow generally points to the north.

2. Interpretation of topographic map

(1) Calculation method of ground height (Figure 1.27 in P 16)

① Altitude (absolute height): the vertical distance from a point on the ground to the sea level.

For example, Mount Everest is 8844.43 meters above sea level, and Turpan Basin is-155 meters above sea level.

② Relative height: the vertical distance from one place to another. Example: the flagpole is off the ground 15m.

⑵ Topographic map types: contour topographic map, layered color topographic map and topographic profile map.

Contour: A line on a map connecting points at the same height.

Isobathymetric line: Connect points with the same depth in the ocean into a line on the map.

⑶ Interpretation of contour topographic map: (P 16 map 1.29)

① Judging the steepness of slope according to the density of contour lines: sparse contour lines indicate gentle slope; Dense contours indicate steep slopes.

② According to the contour shape, determine the terrain type: peak, ridge, valley, saddle and steep cliff. The curved part of the contour line protrudes upward to indicate the valley and downward to indicate the ridge; The part between the two peaks is a saddle; Where contour lines overlap, it means a steep cliff.

(4) Five basic landforms on land: plains, plateaus, mountains, hills and basins. On topographic maps, elevation is used to represent the ups and downs of the ground. On the layered color topographic map, green represents plains, blue represents oceans, yellow represents alpine plateaus, and white represents glaciers.

Step 3 get information from the map

⑴ Common map types: guide map, traffic map and administrative map.

(2) The corresponding relationship between scale size and map scope and details:

The size of the scope indicates the detail or conciseness of the content.

Large-scale small details

Small-scale oversimplification

In the case of the same map, the larger the scale, the smaller the field scope and the more detailed the geographical information; or vice versa, Dallas to the auditorium

Chapter II Land and Sea

5] Common weather symbols (Figure 3.6 on page 46)

We need clean air.

Evaluation method of air quality: the level of air quality is related to the amount of pollutants contained in the air, which is expressed by pollution index. The pollution index is small, which is beneficial to human health; A large pollution index is harmful to human health.

Air quality level, air pollution index and air quality status

First class 1~50 excellent

Secondary 5 1~ 100 is good.

3. Temperature distribution

(1) isotherm: the connection of points with the same temperature.

⑵ indicates that the temperature varies around the world, which is usually represented by an isotherm diagram.

⑶ Influencing factors: latitude position, land and sea position and topography.

(4) Distribution law:

① Latitude difference: Generally, the temperature is high at low latitudes and low at high latitudes. (Figure 3 in P53.17)

② Sea-land difference: the land temperature is high and the ocean temperature is low in the same latitude zone in summer; Winter is the opposite.

③ Vertical variation: the temperature decreases with the elevation, and the temperature decreases by about 0.6℃ with each elevation of 100 m..

5] Interpretation of isotherm diagram:

① The isotherm is closed, with a high temperature center and a low temperature center.

② Where isotherms are dense, the temperature difference is large; Where the isotherm is sparse, the temperature difference is small.
