Comparison of physical geography and human geography between Central Asia and North America

Geographical location: located in the middle of Eurasia, far from the sea;

(2) Terrain: the terrain is high in the east and low in the west, and the terrain is mainly plains and hills;

③ Climate: mostly temperate continental climate, with intense heat in winter and scarce precipitation;

(4) Rivers and lakes: most of them are inland rivers and lakes, and a few rivers are mostly saline lakes;

⑤ Vegetation: mainly grassland and desert.

Second, North America.

1. The coastal mountains press the Pacific coast, and the windward slope is rich in topographic precipitation. However, the coastal mountains prevented the warm and humid westerly winds from advancing eastward in the Pacific Ocean, and restricted the temperate maritime climate and the Mediterranean climate to extend eastward to the west of the mountains, so that the above two climates were distributed in the coastal areas in a north-south direction. Due to the terrain barrier, it is difficult for marine water vapor to enter the mountain plateau basin, so the climate is dry and presents a desert scene.

2. The northwest slope of the eastern highland meets the northwest wind in winter, which often causes heavy snow; The southeast slope lifts the Atlantic water vapor, resulting in topographic precipitation. However, due to the low altitude and poor continuity in the east, the dry and cold northwest wind in winter can affect the east coast, and the warm and humid airflow from the Atlantic Ocean can also cross the highlands and enter the inland in summer.

3. The seasonal variation of temperature and precipitation in the central plain is the largest, which is continental. This is because the central plain is low and flat, there are no east-west mountains, and the north and south are open, which makes the north-south airflow unimpeded. In winter, the polar cold air mass can go south and suddenly cool down. In summer, the tropical heating mass from the Gulf of Mexico can go north freely, and the weather is sultry and rainy. Under the control of cold and warm air masses, a temperate continental climate has formed in the Central Plains, with strong seasonal changes in temperature and precipitation and strong continental nature. Residents are a large collection of immigrants, with more English and French, and English is the main language. Native Indians and Inuit are yellow people.
