Geography 31 Why, Geography 6th Choice, Why C

Negative correlation is the opposite of positive correlation, and negative correlation is generally understood to mean that in the case of a given value, one of the two variables increases, and the other decreases, like an inverse proportional relationship.

In layman's terms, environmental population capacity is the maximum number of people that can be sustainably supported by the total amount of resources, scientific and technological level, education, and consumption level of a country or region. Therefore, the ambient population capacity is a maximum (constant value). Then, when the per capita consumption level increases, the social output value or social wealth consumed will also increase, and the number of people to feed will naturally decrease.

a option should be positively correlated, b Although the number of resources available within a given area is also relative, it is also positively correlated if it is only a resource.

d Human beings are part of nature, and they prefer to live in a place with better natural conditions than in a harsh natural environment.

The total amount of resource use is equal to the environmental population capacity multiplied by the per capita consumption.

As the per capita consumption level increases, the social output value or social wealth consumed also increases, and the number of people supported naturally decreases.

In fact, there is a drop in the textbook Is it high school?

The high level of consumption, the high consumption of resources, and the high pressure on the environment, the population capacity is naturally small, so it is negatively correlated.

6. Select C on the same isobaric surface with equal air pressure;

In the vertical direction, the higher the altitude, the lower the air pressure - b is below the isobaric surface a, b a, and c is above a, so a c; d is below b, so d b.

So d b a c. So the lowest air pressure value is c.

Look at the diagram with two lines like parentheses, that is the range of the air mass, and the air pressure on the side of the air mass is the lowest. If the air pressure in the unified horizontal line of A and B is the same, the air pressure on the ground will be higher than that in the sky

If there is a rock dissolution, you should consider the limestone (which is very eroded) first

In recent years, people have destroyed vegetation, reclaimed wasteland, and enclosed lakes to create fields... Serious damage to vegetation and destruction of biodiversity are all human activities.

So choose C

Surface water loss and rock dissolution are mainly karst landforms.

I can't explain it to you, and the other answers don't make sense.

The type of land used for the layout of the city's land depends on the level of land rent that is willing to be paid, i.e., land**; With the improvement of traffic conditions, the urban spatial structure has changed, and although the development history and living habits can affect the spatial structure, they are not the main factors, so choose a and c).

Sugarcane and rice are relatively cheap, indicating that the yield of sugarcane and rice in this area is relatively abundant, and the "southern Fujian triangle" meets the conditions. From the perspective of economic benefits, flowers and vegetables are more profitable and yieldy).

It must be b, reason: on the winter solstice, the Antarctic Circle is a polar day, so the day length of Kunlun Station and Zhongshan Station is 24 hours; The longitude of Kunlun Station and Zhongshan Station is east longitude, whoever has a large longitude will enter the new day in advance, and the Great Wall Station is the west longitude, and the date is later than them.

A is obviously wrong, the latitude of the Great Wall Station is less than the latitude of the Polar Circle, so the Great Wall Station does not have the phenomenon of polar day and night;

d is also wrong, the rotation line speed with a small latitude is large, so the maximum rotation line speed should be the Great Wall Station.

b。Answer: You can refer to the "2009 College Entrance Examination Geography Hot Topics - Antarctic Kunlun Station".

b, should. The latitude of Zhongshan Station is not very clear, if it is in the Polar Circle, it is the same polar day, and the length of the day is not divided into long and short.

b Kunlun Station is located in the easternmost place.

The sunrise time in various parts of our province is the latest of the year, so this is the winter solstice day in the northern hemisphere, and the polar night phenomenon occurs in the Arctic Circle and its north, and the polar day phenomenon occurs in the Antarctic Circle and its south.

a, the Great Wall station is located north of the Antarctic Circle, so there is no polar day phenomenon c, Kunlun Station and Zhongshan are located in the south of the Antarctic Circle, so there is a polar day phenomenon d, the speed of the Earth's rotation line decreases from the equator to the poles, and the Great Wall Station has the lowest latitude so the largest is the Great Wall Station.

Hello, first look at the sake brewery, and then of course think that it is raw material-oriented, and the raw material for this production needs water, and you must find a place close to the water source.

This question Z is closest to the water source, so it can only be D.
