Simple geographical problems

Scale = distance on the map/actual distance (pay attention to the conversion unit)

The distribution of oceans and land on the earth's surface.

The ocean accounts for 7 1% of the earth, and the land accounts for 29%.

Is the land and sea distribution fixed?

number

The difference between weather and climate

The weather is limited to a certain time or a certain day; Climate refers to the perennial characteristics of a place.

weather symbol

The sun, sunny;

The sun adds clouds, and it turns sunny to cloudy;

A cloud, cloudy;

There is a row of rain in the shade, light rain; Two rows of rain are moderate rain, and three rows of rain are heavy rain;

Symbols like the letter f, but not f, are six winds; Like a small flag, it is eight winds; The blowing direction is different, so is the blowing direction.

Snowflakes are light snow; Two snowflakes refer to snow; Three snowflakes and heavy snow.

Examples are given to illustrate the impact of human activities on the atmosphere and the importance of protecting the atmospheric environment.

Harmful gases such as deforestation, automobile exhaust emissions and industrial exhaust emissions have a very important impact on the atmosphere; If human beings continue like this, the earth will become a big greenhouse and will face serious problems such as melting glaciers (fresh water resources) and rising sea levels.

The influence of latitude position and ocean distribution topography on climate is analyzed with examples.

Different latitudes, different climates;

Compared with land and sea in latitude, the temperature is high in summer, low in winter, less precipitation in inland, and the opposite is true in ocean. For example, Shanghai and Urumqi;

The temperature decreases with the elevation, with more precipitation on windward slope and less precipitation on leeward slope.

Warm current temperature is higher, precipitation is more, cold current temperature is lower and precipitation is less.

Give examples to illustrate the impact of population problems on the environment and social economy.

China has a large population base, rapid growth, uneven distribution and great population pressure.

Large population, less per capita resources; The population quality is not high, employment difficulties and other issues.

How to treat the cultural differences in the world

Respect foreign culture and promote local culture.

The difference between developing countries and developed countries

The consumption capacity, medical conditions, living standards and urbanization level of developing countries are lower than those of developed countries;

Describe the characteristics of population distribution in China.

Heihe-Tengchong line, with more in the southeast and less in the northwest.

Give examples to illustrate what natural resources are and what types they have.

Land resources, mineral resources, hydropower and water resources, marine resources.

Tell me the spatial and temporal distribution characteristics of resources and their influence on social and economic development with data

Uneven distribution, relatively concentrated; Restrict the development of regional economy.

Compare the characteristics of different modes of transportation and tell the general pattern of China's transportation network.

Railways and railway networks are dense.

Highway, extending in all directions

Developed maritime transport

Overall pattern: dense in the east and sparse in the west.

Explain the necessity of developing agriculture according to local conditions.

Mainly from natural conditions and social conditions.

If there is no suitable climate and soil conditions, there will be no good harvest;

If it is not based on social conditions such as market demand and national policies, it will be a loss-making business after all.

Describe the geographical distribution of industries in China and its role in the development of high-paying technology industries.

China's industries are mainly distributed in coastal areas,

High-tech industries promote the economic development of China and accelerate the adjustment of industrial structure.
