Exercise Solution: Geography Textbook Grade 10 Exercise 34: Practice: Drawing a Situation Chart of Industrial Production of Some Industrial Products Worldwide
Page 133 Geography Textbook Grade 10:
Based on the given data table, perform the following tasks:
* Solution:
1. Draw a chart
a) Calculate and prepare a data table showing the growth rate
GROWTH RATE OF SOME INDUSTRIAL PRODUCTS IN THE WORLD, PERIOD
b. Draw a chart
2. Comment on the chart and explain the reasons
- Coal, oil, and electricity are products of the energy industry. Steel is a product of the metallurgical industry.
- Generally, from 1950 to 2003, the production value of the energy industry (coal, oil, electricity) and the metallurgical industry (steel) increased, but the growth rates were not consistent. Since 1970, all industries have made significant breakthroughs.
- Electricity: The growth rate was very fast, reaching 1535% in 53 years, with an average annual increase of 29%. Since the 1980s, the growth rate has been very high, reaching 1223% per year in 1990 and 1535% per year in 2003 compared to 1950. This rapid growth is due to the exploitation of new energy sources such as atomic energy, solar energy, wind energy, etc.; and also due to the increasing demand of the industry and life.
- Oil: The growth rate was quite fast, reaching 746%, with an average annual increase of 14%. This increase is due to the increasing demand for fuel in the world market; especially for transportation, energy industry, and oil refining.
- Coal: The growth rate is quite steady, reaching 291%, with an average annual increase of only 5.5%. Since the 1990s, the growth rate has slowed down due to the pollution caused by this type of fuel, but recently it has been recovering due to the crisis in the oil industry.
- Steel: The growth rate was quite high, reaching 460%, with an average annual increase of 8.7%. Steel is widely used in industries, especially in mechanical engineering, construction, and daily life, so the market demand is high.
