Geographical knowledge, in a hurry, who will!!

1。In the northern part of the Amazon region, coal, the main coalfields are distributed in the Paraná Basin.

Iron ore, mostly found in the states of Minas Gerais and Pará.

Manganese, mainly found in the Amapá region, Minas Gerais and Barra, with the main mining area being the Azul manganese deposit in the Karajas region.

Chromium, mainly found in Bahia.

Bauxite, mainly in the Amazon Basin, Minas Gerais, Poçus di Caldas, etc.

Copper, found in Bahia and Calajas.

Nickel, mainly found in the states of Goiás and Minas Gerais.

Gold mines, almost all over the country.

2.The reason for the abundance of freshwater resources is because of the Amazon River, which has a tropical climate, so that the period of precipitation is abundant!

3.Water pollution is mainly the pollution of industrial production and the pollution of domestic wastewater.

4. In the southeast corner of Brazil, Rio de Janeiro, São Paulo, and Brasilia, now the capital.

Reasons: 1. Rio de Janeiro, Sao Paulo and other areas in the southeast are traditional industrial areas in Brazil, with developed economies and various industries distributed here, and at the same time, there are the largest cities and largest ports in Brazil, which are seriously polluted.

2. Brasilia is the new capital, but because it is a world-famous megacity, with a population of more than 10 million, and is located on the Brazilian plateau, there is relatively little precipitation.

The development of high-tech industries will increase the unemployment rate in the United States. Because of the development of high-tech industries, low-tech industries such as manufacturing will be transferred to other countries, and the possibility of unemployment will increase for low-quality workers in the United States.

Impact on the U.S. economy: The first is to promote economic development, and the second is to improve the economic and industrial structure.

Not particularly good, please let me know if there is anything to add.

You have so many questions that you can go to the world geography textbooks one by one, and look for them all.

Briefly say what you think, I don't know if it's right.

Possible causes of the first question: ocean current (Japanese warm current), topography (basin), heat island effect The second question is the transfer of resources and labor, the advantages can consider the abundance of resources and labor, and the disadvantages can consider environmental pollution, traffic pressure, etc.

The third question can consider the advantages of the provincial capital, such as the administrative and cultural center, and the second question is transportation, population, etc., and the fourth question is to undertake the cement plant, which can consider the transportation, population, and environmental aspects.

You didn't take all the questions in question 27 (2), but you answered all the other questions, please give points.
