How much do you know about the learning skills of geography in junior high school?

When learning junior high school geography, we need to have a professional way, carefully understand, understand the knowledge learned, and clarify the knowledge points and interrelationships of each part, we must also make full use of this knowledge, so that our junior high school geography results are better, so that we can get better development.

In learning, we need to use junior high school geography to analyze and solve problems in an all-round way, we need to practice a lot, complete the homework assigned by the teacher, take exams, and answer various questions, so how can we solve these difficulties quickly, accurately and completely? This requires us to understand and easily solve these difficulties, and slowly improve our own capabilities.

Here are some ways to improve your ability to understand problems in geography in junior high school, as well as ideas for solving them.

The key to understanding books is that they are a prerequisite for improving their abilities.

All kinds of local problems are inseparable from location, mastering specific location knowledge is the key to junior high school geography, location can be reflected through a variety of maps, such as geography textbooks, which contain a wealth of knowledge (knowledge and skills), in learning, you need to know how books describe various problems, summary, analysis, and their distribution on the map of the way of expression, and the combination of the two, to form a variety of geographical things, location contour map, In order to understand all the content and skills required to understand junior high school geography, clarify the characteristics, location, how to form and other key points of each phenomenon, so that the performance of junior high school geography can be improved to a certain extent, and correctly answer various geographical questions such as maps and reading maps, for example, understand the causes and laws that affect climate, and also master temperature, precipitation and other climate data, and it is possible to use relevant climate data, climate charts (such as monthly and annual precipitation data), changes and precipitation, etc., or the location and characteristics of a certain place, etc., You can make correct judgments and answers, analyze each problem in detail, and then make targeted solutions.

And if you can't solve the problem by yourself in the study, you need to discuss it with the teacher, so that you can solve every difficulty in time, and add textbook knowledge and extracurricular knowledge, you can make your knowledge content more abundant, and improve your junior high school geography scores, but the knowledge you have learned needs to be practiced again after a period of time, otherwise you may forget.

The above is the skills of learning geography in junior high school, through the above content, after learning the above methods, your grades will be improved to a certain extent.

Part I....World Geography (Part I).

Knowledge point 1: Learn to read the basic elements of the map: scale, direction, legend and annotation.

1. Scale bar.

Definition of scale: The so-called scale bar is compared with it, which is expressed by the formula as: scale distance on the map and distance from the field.

There are three representations of the scale: e.g., 1:1000000 linear segment, e.g., e.g., 1 cm on the map represents the distance from the field of 10 kilometers.

The size of the scale: The scale bar is a fraction, the denominator, and the smaller the scale.

Scale calculation: 1 cm on the map = how many kilometers or meters of the distance from the field.

Application: The same picture sheet, the larger the scale, the more the range drawn, the more the same picture sheet of the representation content, the smaller the scale, the more the range drawn, the more the content represented;

2. Direction: General orientation method: facing the map, usually ","

Pointing Direction Method: According to the pointing point orientation, the arrow pointing to the target generally points to the square.

The direction of the warp and weft lines: the warp indicates the direction, and the weft line indicates the direction; Stand at the North Pole with all directions around; Standing at the South Pole, the surrounding directions are facing.

3. Legends and annotations (some commonly used legends textbooks P10 Figure 1-17).

A legend is a map that represents a variety of geographical things; The annotation is the sum on the map.

Knowledge point 2: The topography of the world.

1. Land topography.

4. The vertical distance above a certain point on the ground is called elevation.

The distance at which one place is higher than another is called relative height.

The various undulating forms of the earth's surface are collectively called. Topography refers to the general tendency of the earth's surface to rise and fall.

5. The terrain of land is divided into mountains: altitude note: the determination of the eastern and western hemispheres

Last year I worked hard to learn geography and biology! After scoring 191 points, I was told that I only needed 110 to pass the high school entrance examination this year! I regret it!

If you want information, I recommend using the "New Curriculum Standards" of Geography and the "100 Days of Fire" of Biology, the exam questions are very simple, don't worry! But be careful.

Me too, oh, you can see if you can

1. The shape and size of the earth The earth is an irregular sphere with slightly flattened poles, and its average diameter is 6,371 meters.

2. Latitude and latitude On the globe, the circle that circles around the globe in the east-west direction is called the latitude. All the weft threads are circles and can be called weft coils; The length of the weft coil is long and short, the equator is the longest, and gradually shortens towards the poles, and finally becomes a point. The parallels all indicate the east-west direction.

The equator is the longest and parallel, about 40,000 kilometers long. It is at an equal distance from the poles and divides the earth into two hemispheres, north and south. The equator is the zero degree latitude on a globe. The latitude north of the equator is called the northern latitude, and it is customary to use it.
