Junior High School Geography Summary of knowledge points

1. Map

1. Expression methods of scale: literal, line segment, digital

2. Comparison of scale sizes: The larger the denominator, the smaller the scale; the smaller the denominator, the larger the scale.

3. The larger the scale, the smaller the range of representation and the more detailed the content; the smaller the scale, the larger the range of representation and the simpler the content.

4. Scale = distance on the map ÷ distance on the ground

5. Expression method of direction on the map:

For general maps, use the general orientation method: facing Map, up, north, down, south, left, west, right, east.

For maps with indicators, use the pointing method: the direction of the arrow pointing to the indicator generally points to the north.

For maps with a graticule, use the graticule orientation method: longitude lines indicate the north-south direction, and latitude lines indicate the east-west direction.

6. Legend: Symbols representing various geographical things on the map. (Remember the commonly used legends)

7. Notes: On the map, the words used to describe the names of mountains, rivers, countries, cities, etc., as well as the numbers indicating the height of the mountain and the depth of the water.

8. Altitude (absolute height): the vertical distance above sea level at a certain point on the earth's surface. Relative height: The vertical distance that one point on the Earth's surface is higher than another.

Contour lines: lines connecting points with the same altitude on a map.

9. On a contour topographic map, dense contour lines indicate a steeper slope; sparse contour lines indicate a gentler slope.

10. Determine the terrain based on the characteristics of contour lines:

Top of the mountain: The contour line is high in the middle and low on the surrounding sides.

Ridge: Contour lines bulge downwards.

Valley: Contour lines bulge upwards.

Saddle: The contour lines on both sides are relatively high.

Cliff: A place where multiple contour lines overlap.

Extended Reading: Practical Skills in Geography for Junior High Schools

This requires making full use of globes and maps to know the spatial location and spatial connections of the above-mentioned geographical things learned.

Learning to use textbooks is not only a tool for mastering knowledge and skills, but also a basis for cultivating self-study ability. The table of contents reminds you of the main points and connections of the whole book. You should read it frequently so that you have a clear idea of ??the contents of the whole book. Read the text carefully, think deeply, grasp the key points, write down questions, pay special attention to illustrations and tables, and understand the issues illustrated by the charts.

In addition. To study geography, you need to understand the content in the textbooks and learn skills such as reading, using, and drawing geographical charts. You must also pay attention to nature and society, take a look at the appearance of the local geographical environment, and how people live in the area. When observing, use your brain to think about it and ask more questions about why.

In addition to these, we should also read more geography books, newspapers, watch TV programs and listen to geography-related content on the radio, and obtain geography-related information from the computer network, which can enrich our geography. Knowledge, exercise our talents, so that we can learn geography better!
