The knowledge points of the high school geography exam must be memorized in the high school geograph

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 various problems, 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 it is formed 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 map, read maps and other geographical problems, for example, understand the causes and laws that affect climate, and also master temperature, precipitation and other climate data, 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 analyze each problem in detail, and then solve it in a targeted manner.

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.

There are a lot of knowledge points in the high school geography exam.

The knowledge points that must be memorized in the high school geography exam are as follows:

Determine the sunrise and sunset moments:

1. The sunrise time of a place is the place where the latitude line and the morning line intersect.

2. When calculating, you can use the noon time - half the day length, or the midnight time + half the night length.

3. The sunset time of a certain place is the place where the latitude line and the dusk line intersect.

4. The calculation can be calculated at noon time + half the length of the day, or, midnight time - half the length of the night + 1 day.

5. At the spring or autumn equinox, the global day and night are equinox, with sunrise at 6 o'clock and sunset at 6 o'clock.

6. The square of day and night on the equator is all year round, and the sunrise is 6 o'clock and sunset at 18 o'clock throughout the year.

Determine the height of the sun:

1. The height of the sun in the day hemisphere is greater than zero, and the maximum value occurs at noon, that is, at 12 o'clock local time.

2. The height of the sun in the night hemisphere is less than zero, and the minimum value occurs at midnight, that is, at 0:00 local time.

3. The height of the sun on the morning and dusk line (circle) is equal to zero.

Noon Sun Altitude:

1. The height of the sun at noon is equal to 90°.

2. There are two parallels with the same height of the sun at noon on the same day, and these two parallels are distributed on both sides of the direct parallel, which is equal to the latitude difference of the direct parallel.

3. The height of the noon sun on a certain parallel, which is equal to 90°, minus the latitude difference between the parallels and the direct parallels.

Diequix to solar altitude distribution law:

1. At the vernal equinox, the sun shines directly on the equator, and the height of the sun at noon on the equator is 90°, and the height of the sun at noon gradually decreases from the equator to the poles.

2. During the summer solstice, the sun shines directly on the Tropic of Cancer, the height of the sun on the Tropic of Cancer is 90°, and the noon solar height in the area north of the Tropic of Cancer reaches the maximum value of the year, and the southern hemisphere reaches the minimum value.

3. At the autumn equinox, the sun shines directly on the equator, and the noon solar height on the equator is 90°, and the noon solar height gradually decreases from the equator to the poles.

4. During the winter solstice, the sun shines directly on the Tropic of Capricorn, the height of the sun on the Tropic of Cancer is 90°, and the noon solar height in the north and south of the Tropic of Cancer reaches the maximum value of the year, and the northern hemisphere reaches the minimum value.

Determine the date cut-off line:

1. There are two date demarcation lines, one is the international date line, referred to as the date line, which has the same time on both sides of the line, and the date difference is one day. The other date dividing line is the meridian at 0:00 local time, which is the 24:00 of the previous day and the 0:00 of the following day.

The point meridian line goes east to the date line one day earlier; The 0:00 meridian goes west to the date line one day later.

3. When the direct point of the sun is on the east longitude and the 0 point is at the west longitude, the range of the date on the earth is one day earlier accounts for most of the range.

4. When the direct point of the sun is at west longitude and 0 is at east longitude, the range of the date on the earth is one day earlier accounts for less than half.

5. When the direct point of the sun is on the 0° meridian and the 0 point is on 180°, that is, the date line, the world is the same day.

6. When the direct point of the sun is at 180° and the point of 0 is at 0° meridian, the range of one day earlier and one day later is equal in the world. At this time, Beijing time is 8 o'clock.
