High School Geography and Chinese Geography Partial Knowledge Points

GEI mailbox, send back to you. ok?

1. The level of the celestial system: total galaxy - Milky Way (extragalactic galaxy) - solar system - Earth-Moon system.

2. The conditions for the existence of life on Earth.

Stable solar light conditions.

Relatively safe cosmic environment.

Because the distance between the sun and the earth is moderate, the surface temperature is suitable (the average temperature is 15 degrees).

Because of the Earth's moderate mass and volume, the Earth can attract the atmosphere to form an atmosphere (mainly nitrogen and oxygen).

Formation and presence of liquid water.

3. The impact of solar activity on the earth:

1) Signs of solar activity: sunspots, flares.

2) Impact: Affect the ionosphere and interfere with radio shortwave communications;

the phenomenon of "magnetic storm" and "aurora" is generated;

Affects the Earth's climate.

4. The geographical significance of the rotation of the earth:

Alternation of day and night: the dividing line between the day and night hemispheres - the morning and dusk line (circle) - the time of the intersection with the equator is 6 o'clock and 18 o'clock respectively - the height of the sun is 0 degrees - the plane on which the morning and dusk circle is located is perpendicular to the sun's rays;

Local time difference: morning in the east and evening in the west, longitude varies by 1 hour every 15 degrees.

Geostrophic deflection force: no deviation on the equator, right deviation in the northern hemisphere, left deviation in the southern hemisphere. The deflection force increases with latitude.

5. The geographical significance of the revolution of the earth:

1) Change in the length of day and night:

In the summer half of the Northern Hemisphere, the sun shines directly on the Northern Hemisphere, and the days and nights are short at all latitudes in the Northern Hemisphere, and the higher the latitude, the longer the days and the shorter the nights. On the summer solstice, the day length at all latitudes in the Northern Hemisphere reaches its maximum of the year, and the polar day phenomenon occurs in the Arctic Circle and the areas north of it.

In the winter half of the northern hemisphere, the sun shines directly on the southern hemisphere, and the nights are longer and the days are shorter at all latitudes in the northern hemisphere. On the winter solstice, day lengths at all latitudes in the Northern Hemisphere reach their lowest values of the year, and polar nights occur in the Arctic Circle and areas north of it.

On the day of the vernal and autumnal equinoxes, the sun shines directly on the equator, and the length of day and night is equal to 12 hours each around the world.

The equator equinoxes day and night throughout the year. The situation in the southern hemisphere is the opposite of that in the northern hemisphere.

The role of wetlands.

1. Material production function.

Wetlands have a strong material production function, and they contain abundant animal and plant resources.

2. Atmospheric composition adjustment function.

The abundant plant community in the wetland can absorb a large amount of carbon dioxide gas and release oxygen, and some plants in the wetland also have the function of absorbing harmful gases in the air and can effectively regulate the composition of the atmosphere. At the same time, it is important to note that wetland habitats also emit greenhouse gases such as methane and ammonia.

3. Water regulation function.

Wetlands play an important role in water storage, regulating river runoff, replenishing groundwater and maintaining regional water balance, and are the natural "sponges" for water storage and flood control.

4. Purification function.

Swampy wetlands act like natural filters that help to slow down the flow of water as it passes through wetlands containing toxins and impurities (pesticides, domestic sewage and industrial effluents), which facilitates the sedimentation and removal of toxins and impurities. Some wetland plants can effectively absorb toxic substances in the water and purify the water.

5. Provide animal habitat functions.

6. Adjust the local microclimate.

The wetland water is evaporated into water vapor, and then in the form of precipitation to the surrounding areas, maintaining local humidity and rainfall, making Ninghe County one of the wetter areas in Tianjin.

Physical Geography:

1) Climate (pay attention to this, because many questions will be used, although it is not explicitly examined, but it is closely related to it, such as agriculture, you don't need to remember too much detail, as long as you remember the general line, which includes a lot, general terrain, climate, wind direction, etc.).

2) Topography (the general topography should be remembered, and its respective characteristics should also be memorized, because this is very often tested) Desertification in the northwest, the influence of the topography of the Qinghai-Tibet Plateau on the northwest wind, the karst topography of the Yunnan-Guizhou Plateau, etc., these questions are very frequent.

3) Agriculture (this combines the above two points, for the general products of each place to remember some, because it will be tested in the comprehensive questions, such as rice in the south, wheat in the north (winter wheat in the south, spring wheat in the north) What are the growth conditions, and the soil, topography, climate, and water source should be considered here).

Human Geography: Well, the main thing is to remember the examples in the book, such as the coal mines in Shanxi and the hydropower in Sichuan, not only to remember these examples, but also to figure out why these properties are there, that is, the conditions for producing these properties, such as hydropower, hydropower in the south, the two most important conditions are to have a large amount of water resources, and one is to have topographical conditions - a large terrain difference. Figure out these, you can draw inferences, the questions on the test paper can't be the same as the book, but everything changes, no matter what the test paper says, as long as it meets the conditions, those on the book can be set up. For example, acid rain caused by industrial pollution, as long as it is the acid gas produced, that is, the emission of exhaust gas, no matter in the first place, acid rain will be generated.

In fact, the Chinese geography exam comes and goes, the most important thing is to sum up the experience in the questions, I took the college entrance examination two years ago, the whole senior year of high school basically did not turn over the geography book again, and the test papers were also very few, (I graduated from the third year of high school, I dared to tell my geography teacher about it.) Because I got an A+ in geography and I studied history, this is also the case).

One reason is that my language is not good, and the Jiangsu college entrance examination depends on the number of words, and the other is that there are some questions, no matter how to change the statement, the answer is still that, it is useless, so if you want to take the college entrance examination in high school geography, it is best to pay attention to the summary when you start a round of review in the second year of high school, so as not to be distracted in the third year of high school. If you are taking the college entrance examination, then just remember what the teacher said when he reviewed for you.

The above is my personal experience, I hope it will be helpful to you.

Topography, topography, climate, agriculture, industry...

Let me first talk about the compulsory one, the knowledge points of the compulsory one is the most, but also the most difficult, if you master the compulsory one, the rest will be easy to understand, first of all, you must master the seven air pressure belts and six wind belts, as well as the seasonal movement of the air pressure belt and the wind belt, there are many topics that have evolved from it.

1. Master the map of the global wind bands of the pressure zone, remember the distribution and name of each wind band, then the prevailing wind direction of each wind zone (the wind direction is related to the geostrophic deflection force), and whether the air currents over each pressure zone are rising or sinking (and their impact on the local climate).

2. The seasonal movement of the global pressure belt and wind belt, through the application of this map, the local climate, wind direction, season, etc. can be judged.

3 Keep in mind the above two diagrams, and then combine them to remember the distribution pattern map of the northern hemisphere climate zone type (the corresponding natural zone name should also be noted), the content of these three maps must be combined to remember, and after remembering these three, you must also do climate exercises, which is mainly like this.

There is not much knowledge about the water cycle. Understand the sea and land circulation, the sea circulation, and the land circulation, of course, you have to understand, but this part is not often tested.

Crustal movements mainly identify anticline (suitable for resources such as coal), anticline (suitable for resources such as natural gas), and faults. There are also several types of rocks and their genesis.

The integrity and diversity of the geographical environment is very important.

All right. I'm a graduate party, and that's all I can think about now. Hope it helps you pull.

I was good at geography when I went to school, and I couldn't get a score of 95 in geography in the comprehensive exam.

The key to learning geography well is to be familiar with every area map, topographic map, and precipitation map.

If you master the map, you will master 80% of the geography, and the exam will give you a map, and if you don't know what it is, no matter how good the basic knowledge is, it will be in vain.

Don't listen to those nonsense, geography is a special subject, it is a liberal arts in high school, and it belongs to science in college, according to the knowledge structure, it belongs to science in the first semester of high school, and the latter belongs to liberal arts, the geography in the first semester tests your spatial imagination ability, you must think more, do more questions, remember to think in front, you must close your eyes and think more, otherwise it will be difficult for you to master. The next few books are basically liberal arts, and the key is to understand, and you don't need to read it like political history, you have to read it silently to understand.

Learning geography needs to cultivate your own interests, you can look at the map, it is very helpful to cultivate interests, what is the climate, what is the place, what is it, some people tell you how to master how to remember what name Ah, those (he) (mother) are all nonsense! You tell me!
