Geographic common sense video

1. geography review instruction video for senior three.

The college entrance examination questions take the situation as the clue, the question as the center, the ability test as the leading factor, examine the candidates' basic knowledge and skills of geography, and pay attention to the multi-level and multi-angle analysis and the examination of problem-solving thinking ability.

For this reason, only by mastering the basic knowledge with high quality, building a knowledge structure with the backbone knowledge as the framework, and making inferences about the knowledge, can we talk about comprehensively applying the knowledge we have learned to analyze and solve problems. On the basis of understanding the connotation and extension of knowledge, according to the internal relationship between knowledge, relevant knowledge is integrated with certain clues to form a knowledge structure.

The establishment of knowledge structure based on backbone knowledge has a process of gradual development and perfection. Firstly, the "point knowledge structure" is expanded one by one, and then the "section knowledge structure", "unit knowledge structure" and "subject knowledge structure" are transformed to construct ideas and clues for analyzing and solving problems.

The second round of review focuses on theme review, focusing on the transfer and reorganization of relevant knowledge based on a certain theme, forming a new knowledge structure, and training and cultivating relevant knowledge and ability. Pay attention to the cultivation of geographical ability.

1。 Attach importance to the cultivation of geographical computing ability.

Learning geography requires certain computing power, such as time, date, sun height, scale, altitude, temperature, air pressure, population growth, economic data, etc. These all involve calculation problems. The essence of geographical calculation is the synthesis of geography and mathematics, and it is a mathematical operation process under the guidance of geographical principles.

Among them, mastering geographical principles is the key to cultivate geographical computing ability. 2。

Attach importance to the analysis of reading pictures and the cultivation of spatial thinking ability. It is a major feature of geography comprehensive examination questions to examine geography knowledge with maps as the carrier.

Therefore, when reviewing, students must be instructed to learn how to read and use pictures, put relevant knowledge points into maps, develop good habits of reading and using pictures, pay attention to the training of image-text conversion, construct spatial concepts, expand spatial imagination and carry out spatial thinking. When reading and using drawings, we should pay attention to four points: (1) reading relevant information from drawings; (2) Will use maps to express relevant information; (3) being able to judge the geographical position; (4) Using the intuition of maps to solve abstract geographical problems.

3。 Attach importance to the extraction of geographic information and the cultivation of processing ability.

When reviewing, we should consciously strengthen the cultivation of information processing ability such as extraction and judgment, reasoning, analysis and induction of geographic information, and attach importance to the thinking process of information extraction and processing. 4。

Attach importance to knowledge transfer ability and training. Geography has the characteristics of timeliness and neutrality, and pays attention to the practical application of laws and principles.

Therefore, in review, we should not only deepen our understanding of laws and principles, but also learn to use them flexibly and timely. 5。

Attach importance to the cultivation of expressive ability. Inaccurate expression is also a factor of losing more points in college entrance examination, so students should be guided to pay attention to the accuracy of language expression and try to use geographical terms in review.

Judging from the content of geography examination questions in recent years, the key contents of the investigation are: (1) geographical position, the most important position is latitude and longitude, and several important latitude and longitude lines should be mastered when reviewing; (2) time calculation; (3) weather and climate; (4) Isogram; (5) regional geography; (6) Environmental problems. This knowledge needs to be taught and practiced more, so as to achieve the effect of drawing inferences from others.

Social hot issues are often the focus of comprehensive literature examination. Taking hot spots as the spatial background, explaining regional problems with the basic principles of geography and analyzing regional development are the main ways to study hot spots.

This hot spot may be a hot spot of current politics or a key subject, especially a major issue related to human development resources, environment, population and sustainable development, and it is also a place with high frequency of investigation. For example, sandstorms in the north, soil erosion in the Loess Plateau, river pollution and so on.

2. The video of the first geography lesson in the seventh grade is urgently needed. I need to preview before class.

chapter one

1, geography, nature, humanities

1. Respect the laws of nature. Two. According to local conditions, foster strengths and avoid weaknesses. Three. Have the concept of sustainable development.

The natural environment and resources on which we live are not only inherited from our parents, but also borrowed from future generations.

2. Earth size: Earth surface area: 5 1 100 million square kilometers; Average diameter: 6371km; The maximum circumference is about 40,000 kilometers.

3. Weft: the weft indicates the east-west direction and is circular; The length is different, the equator is the longest, and it gradually shortens to a point towards the poles.

The north of the equator is called north latitude, and "n" means; South of the equator is called south latitude, and "S" means.

4. Meridian: Meridian indicates the north-south direction; Semicircular; They are all the same length.

The west of longitude 0 is called the west longitude, and "W" means; East of longitude 0 is called east longitude, and "e" means.

5. Earth axis: Earth rotation axis.

6. North Pole: the intersection of the northern section of the earth's axis and the earth's surface.

7. South Pole: the intersection of the southern section of the earth's axis and the earth's surface.

8. The dividing line between the northern and southern hemispheres: the equator.

9. the dividing line between the eastern and western hemispheres: east longitude 160 degrees west longitude 20 degrees (prime meridian)

10, Earth rotation: direction: from west to east cycle: 24 hours.

1 1, the revolution of the earth: direction: from west to east cycle: one year.

12, the relationship between the earth's revolution and the seasons:

13, geographical phenomena related to the earth's rotation and revolution:

The date of the festival, the location of direct sunlight in the northern hemisphere, and the length of day and night.

The vernal equinox is around 2 1 on March, and the equatorial world in the northern hemisphere is equal day and night in spring.

Around June 22nd, the solstice in summer, the Tropic of Cancer in the northern hemisphere has long days and short nights.

Around September 23, the autumn equinox, the northern hemisphere, the equator in autumn, the world is equal to day and night.

Winter solstice 65438+February 22, the tropic of Capricorn in the northern hemisphere has short days and long nights.

Rotation: alternating day and night

Earth motion: time difference in different places

Revolution: the change of the height of the sun at noon in a year

Changes in the length of day and night in a year: changes in the four seasons

14, divided into five regions: the northern cold region is located at 66.5 degrees north latitude, and the southern cold region is located at 66.5 degrees south latitude, with extreme phenomena of day and night, and the climate is cold all year round; The northern temperate zone lies between 66.5 and 23.5 degrees north latitude, and the southern temperate zone lies between 66.5 and 23.5 degrees south latitude, with obvious seasonal changes. The tropics are located between 23.5 degrees north latitude and 23.5 degrees south latitude, and the climate is hot all year round.

15, elevation: the vertical distance above sea level at a certain point on the ground.

16, contour line: mark the altitude of each place on the map, and then connect the points with the same altitude into a line.

Features: 1, where the slope is steep and the contour lines are dense. 2. Where the slope is gentle, the contour lines are sparse.
