Explanation

To use nature correctly and protect it, a large natural region is divided into smaller parts: natural-geographic sub-regions, groups of natural districts and natural districts. Because of climate differences two sub-regions are distinguished in Central Asia: Turan and Kazakhstan. In the Turan sub-region the climate has subtropical features: winters are relatively mild, most precipitation falls in spring so ephemerals sprout in spring, and summer is scorching and rainless. The Kazakhstan sub-region has a temperate climate: precipitation is low but nearly equally spread over the seasons, winter is very cold, and ephemerals do not grow. In the mountains spring and summer come late, autumn and winter early, windward slopes get more precipitation, and mountain-valley winds blow in valleys; in the Khujand corridor linking the Fergana Valley with Mirzachul the local Bekabad wind blows. In each sub-region groups of mountain districts and plain districts are distinguished separately.

Worked examples
Tashkent, Samarkand and Termez lie in the Turan sub-region, while Astana and Karaganda are in the Kazakhstan sub-region or close to it.
Tirich Mir in the Hindu Kush (about 7700 m) is the highest point of the Turan sub-region, while Pobeda Peak in the Tien Shan (7439 m) falls in the Kazakhstan sub-region.
Class activity

“Two poles”: the class splits into “Turan” and “Kazakhstan” groups. Each writes 5 features (winter, summer, precipitation, plants, soil) of its sub-region and then the groups check each other.

Practice
1
Which two sub-regions are distinguished in Central Asia?
2
In which sub-region do ephemerals grow and why?
3
Tirich Mir is about 7700 m and Pobeda Peak is 7439 m. About what is the difference in metres?
4
Why is natural-geographic zoning needed for the economy? Give an example.
