Analysis on the location conditions of nonferrous metal smelting from the perspective of high school geography. According to geography textbooks, non-ferrous metal smelting is a power-led industry, so electricity must be considered when analyzing the location.

Generally, it is analyzed from the following aspects:

First, motivation. It is best to use cheap energy such as hydropower and thermal power.

Second, non-ferrous metal mineral resources are abundant.

Third, traffic conditions.

Fourth, the water source conditions.

5. Industrial base.

6. National policies and technologies.

According to the order from important to unimportant, it is mainly the first two aspects.

For example, the conditions for developing nonferrous metal smelting in the Yangtze River basin in China are abundant and cheap hydropower and abundant nonferrous metal resources. The location condition of Shanxi aluminum smelting is rich in thermal power and aluminum ore resources.

The above is beneficial, and the disadvantage is mainly environmental pollution.

From the perspective of high school geography, the reason of heavy snow in Altay, Xinjiang is 1. The water vapor formed in the Mediterranean Sea moves from west to east, affecting northern Xinjiang. There is a natural gap in the terrain of Xinjiang. Facing west, Altai Mountain is located at the gap, and the terrain is getting higher and higher from west to east, which is easy to form topographic precipitation. Coupled with the influence of cold air, the precipitation in Altay increased from 10 last year.

2. It is related to La Ni? a phenomenon ("La Ni? a phenomenon" means that the surface seawater temperature in the equatorial Middle East Pacific region is lower than the multi-year average of 0.5 degrees Celsius for six consecutive months, which will make it colder in winter and hotter in summer. La Nina basically ended in May last year, but the sea surface temperature near the equator in the central and eastern Pacific Ocean is still low. Although it does not meet the criteria for the formation of La Nina phenomenon, it still causes frequent meridional (north-south) airflow exchange. The cold airflow from Siberia meets the warm and humid airflow from the south, causing a lot of precipitation in Altay.

3. The annual precipitation distribution is uneven. Last year, the cold air mainly affected the northern part of China in June 5438+February, and the impact was weak. In June this year, there were frequent cold air activities in 5438+ 10, and warm and humid airflow from the south was also very active. Under the joint action of the two, the precipitation from south to north is relatively large.

What do you want to ask for the analysis of geography reading in senior high school?

From the perspective of high school geography, this paper analyzes the reasons why Beijing won the right to host the Winter Olympics. 1 *** Give unconditional support (China has a unique advantage in hosting the Olympic Games).

People support other cities and give up because they don't.

Social stability: Needless to say, Ukraine knows this.

4 The opponent is too weak Almaty

China has a vast market. The IOC hopes to expand the China market.

High school geography analysis questions ecological problems: serious soil erosion, vegetation destruction, air pollution, serious river pollution and so on.

Countermeasures: shut down and turn to small mines to realize large-scale mining and unified pollution control; Planting and protecting local vegetation; Pollution emission standards, etc.

Analysis of geography topics in senior high school The cycle of day and night on the earth is moderate-there is a change of temperature difference-the change of temperature leads to the change of air pressure-so it can be atmospheric precipitation.
