Summary of geography knowledge points in grade seven

Genius is diligence. Someone once said. If this statement is not completely correct, it is at least largely correct. Learning, even a genius, requires constant practice and memory. The following are some knowledge points of seventh grade geography that I compiled for you, hoping to help you.

Induction of geographical knowledge points in seventh grade

1, the geographical position of the world strait

Malacca Strait: between Malay Peninsula and Sumatra Island; Communicate the South China Sea and the Caspian Sea in the Indian Ocean. The Pacific Ocean-the throat of Indian Ocean shipping is called Japan's "maritime lifeline".

The Strait of Hormuz: The Iranian-Arabian Peninsula is connected with the Persian Gulf-Arabian Sea. The Persian Gulf is the throat leading to the Arabian Sea and the "oil strait" of the world.

Bering Strait: Chukchi Peninsula-alaska peninsula; Communicate the Arctic Ocean-Pacific Ocean. The dividing line between Asia and North America and the passage between the Pacific Ocean and the Arctic Ocean.

Mande Strait: between Arabian Peninsula and African continent; Communicate the Red Sea-Indian Ocean. The main road connecting the Red Sea, the Mediterranean Sea and the Indian Ocean.

Turkey Strait: Between the Black Sea, Aegean Sea and Mediterranean Sea. The Black Sea is the gateway to the Mediterranean and the dividing line between Asia and Europe.

Strait of Gibraltar: Iberian Peninsula-African continent; Communicate the Mediterranean-Atlantic. The Mediterranean Sea is the gateway to the Atlantic Ocean and the only way for Asia-Europe routes.

English Channel: Great Britain-continental Europe; Communication between the North Sea and the Bay of Biscay. The North Sea is the main shipping route of the Atlantic Ocean, and it is the busiest shipping channel with the largest number of ships in the world.

Strait of magellan: between the South American continent and Tierra del Fuego; Communicate the South Atlantic-South Pacific. Large ships and routes between the Atlantic Ocean and the Pacific Ocean.

Drake Strait: between South America and the Antarctic Peninsula; Communicate the Atlantic-South Pacific. The dividing line between South America and Antarctica; The only way for scientific research teams from all over the world to visit Antarctica.

Mozambique channel: Between the African continent and Madagascar. Connecting the South and North Indian Oceans, it is the longest strait in the world.

2. American knowledge points

(1) Bering Strait: the intersection of "three lines" (the dividing line between Asia and North America; The border between Russia and the United States; International date line passes by).

(2) Panama Canal: located in the south of the Central American isthmus, in Panama, connecting the Atlantic Ocean and the Pacific Ocean.

(3) Canada is the country in North America and Brazil is the country in South America.

(4) Main areas: ① Amazon Plain-the plain in the world; ② Brazil Plateau-the largest plateau in the world.

5. Latin America: the American region in the southern United States. Spanish and Portuguese are the main languages, mainly mixed-race.

Residents: ① The residents of North America are mainly from Europe and other countries, mainly white. (2) South America is a melting pot of world races, mainly mixed race.

⑺ Economy: ① The United States is the most powerful capitalist country in the contemporary era. (2) Mexico is dominated by oil industry, and the main food crop is corn. Mexico City, the capital, is the national economic center. Argentina is an important exporter of beef and mutton. Brazil's iron, Mexico's silver, Chile and Peru's copper reserves are the highest in the world. South America exports a lot of coffee, bananas, sugar, cotton and corn.

3. Introduction to Australia

Australia, the sixth largest country in the world, is a country that monopolizes the whole continent in the world and is also a country in Oceania. Australia borders New Zealand in the southeast, Indonesia in the northwest and Papua New Guinea, West Papua and East Timor in the north. Australia is the oldest continent on the earth, an island on the earth and a continent with a single country, with a total area of 7.692 million square kilometers.

4. Submarine topographic features

Submarine topography is the result of global geological evolution, which has experienced a long geological history period under the action of internal and external forces and has become today's state.

According to the basic characteristics of seabed topography, it can be roughly divided into three units: continental margin, ocean basin and mid-ocean ridge. The so-called continental margin, that is, the vast transition zone between the continental surface and the bottom of the ocean, is a huge and complex slope zone, which connects the mainland and the ocean. The global continental margin extends 350,000 kilometers with a total area of about 80 million square kilometers, accounting for about 15.9% of the global surface area.

The topography of continental margin can usually be divided into continental shelf, continental slope, continental uplift, trench, island and other first-class topographic units. The continental margin has been changing constantly throughout the earth's history, and it is also a region rich in geological minerals and the most favorable for mining. Ocean basin is the main part of the ocean, with wide and flat terrain, accounting for about 45% of the ocean area.

The dip angle of ocean basin is small, about 0.20' ~ 0.40', and the depth can extend from continental uplift to about 6000 meters. In the wide ocean basin, because there is no light, the temperature is very low, and the benthic animals in the deep ocean are very rare. The seabed sediments are mainly composed of calcareous and siliceous skeletons of plankton, which breed on the ocean surface and sink into the seabed to add ooze, forming calcareous ooze and siliceous ooze.

Manganese nodule resources with wide distribution and large reserves have been found in seabed sediments with a depth of more than 4700 meters.

Geography must recite knowledge points in the first semester of junior high school

1. Weather has two important characteristics: weather reflects the atmospheric conditions in a short time; At the same time, the weather in different places may be very different.

2. See Figure 3.4 on page 45 of the textbook for wind direction and wind force.

3. Temperature and its distribution

① The temperature in a day appears around 2 pm, and the lowest temperature appears around sunrise.

② In a year, the temperature in July is the lowest in the northern hemisphere, and it is 65438+ 10 in the mainland.

In a year, the temperature in July in the southern hemisphere is the lowest on the mainland, 1.

③ From the equator to the poles, the temperature gradually decreases.

(4) According to the observation, the temperature drops by about 0.6℃ every time the altitude rises 100 meters.

⑤ Use isotherm diagram to show the horizontal distribution of air temperature.

4. Precipitation and its distribution

① Rain, snow and hail falling from the atmosphere are collectively referred to as precipitation. Rainfall is the main form of precipitation.

② From the equator to the poles, the general trend is that the annual precipitation decreases gradually.

③ Near the Tropic of Cancer, there is more precipitation on the east coast of the mainland and less precipitation on the west coast of the mainland.

④ In temperate regions, there is less precipitation in Chinese mainland and more precipitation in coastal areas.

⑤ The distribution of precipitation is represented by isoprecipitation line graph.

6. The world's "rainy pole"-begging for help; The world's "dry pole"-Atacama Desert.

⑦ Usually, there is more precipitation on windward slopes and less precipitation on leeward slopes in mountainous areas.

5. World climate

(1) Climate is the average weather condition of a place for many years, and generally it doesn't change much.

② See page 58 of the textbook for the world climate distribution map.

③ Near the equator (tropical rain forest climate); Polar regions (frigid climate); The east coast of the mainland near the Tropic of Cancer (subtropical monsoon and monsoon humid climate); The west coast of the mainland near the Tropic of Cancer (tropical desert climate); Mid-latitude inland areas (temperate continental climate).

④ Climatic characteristics of tropical rain forest: high temperature and rainy all year round; Mediterranean climate features: less rain in high temperature period and more rain in low temperature period.

⑤ The main factors that affect the climate are latitude, land and sea, topography, temperature and precipitation.

Learning methods and skills of geography in junior one.

Listen carefully in class. Most of the geography in the seventh grade needs to be understood, and it will be much easier to remember after understanding it. So listening in class is the key. Some people think that geography is the liberal arts and the main backrest. If you memorize it, you will get good grades. Actually, it's not. Much depends on understanding. Only by understanding can we get twice the result with half the effort.

Positive thinking, focusing on understanding. There are many parts of seventh grade geography to understand. Most knowledge can't be learned by rote. Even if the knowledge points are memorized, they will not be used in practical exercises, so we must think more and pay attention to understanding.

Pay attention to summing up the law of induction. A lot of junior high school geography knowledge is regular, such as climate type and population distribution. Summing up the rules is easy to learn and remember.

Comparative memory of the same and similar knowledge points. There are many similarities between geographical things and many laws. Therefore, we can easily find out the similarities and similarities among them and compare them for memory and study.

Pay attention to the importance of maps. There is a lot of knowledge in geography that can't be learned and memorized by words alone. Looking at pictures is more important than reading words. Don't forget, maps are a basic tool for learning geography.

Read the textbook 10- 15 minutes every day. Geographical knowledge is complex and there are many knowledge points, so we must review it in time. Keep reading textbooks 15 minutes every day, and long-term persistence will have good results.

Competition law. Collect the knowledge of current geography textbooks, sort out the answers, judge the questions and determine the score of each question. Then divide the class into several groups. Choose a moderator from the class to read the questions and announce the correct answers. Determine another student's statistical score. After the competition, the winning team will be selected and given spiritual and material rewards, and several people with profound geographical knowledge can also be selected. Through this form, students' enthusiasm will be high, they will do a lot of preparatory work in advance, and they will also change from passive to active to review a lot of knowledge.

Drawing method. By drawing geographic information map, students can actively understand relevant knowledge, and then draw the map accurately. And in the group exchange show. Introducing and explaining the geographical knowledge involved in your painting to your classmates will leave a deeper impression on the lecturer himself. It will also leave a clear clue of knowledge in the brain.

Contrast method. Compare the climate characteristics and terrain characteristics of different countries, and deepen understanding and memory in comparison. You can even sort out the comparison results in the form of tables.

Induction. Summarize countries or regions with the same characteristics to reduce the amount of repeated understanding and memory of knowledge. It is also conducive to cultivating students' geographical concentrated thinking and helping students find more effective learning skills.
