Snow Storm In China

The Paleozoic formations of China, excepting only the upper part of the Carboniferous system, are marine, while the Mesozoic and Tertiary deposits are estuarine and freshwater, or else of terrestrial origin. Groups of volcanic cones occur in the Great Plain of north China. In the Liaodong and Shandong Peninsulas, there are basaltic plateaus.
The climate of China varies greatly. The northern zone (containing Beijing) has summer daytime temperatures of more than 30 degrees Celsius and winters of Arctic severity. The central zone (containing Shanghai) has a temperate continental climate with very hot summers and cold winters. The southern zone (containing Guangzhou) has a subtropical climate with very hot summers and mild winters.
Due to a prolonged drought and poor agricultural practices, dust storms have become usual in the spring in China. Dust has blown to southern Mainland China and Taiwan, and has reached the West Coast of the United States. Water, erosion, and pollution control have become important issues in China's relations with other countries.
