This latitude range is located in temperate monsoon humid climate, with flat terrain, rivers providing water irrigation conditions, fertile soil and pleasant climate.
The temperate humid climate is mainly distributed in the mid-latitude zone of eastern North and South America (Mississippi River basin and its east, Argentina and southern Brazil), the southeast coast of Australia and the European plain.
Geomorphology of temperate humid climate
Temperate humid climate and landforms are mainly distributed in mid-latitude areas, and the scope of this climate in the northern hemisphere is much larger than that in the southern hemisphere. Its main characteristics are that the annual average temperature is about 10℃ and the annual rainfall is about 800 ml. Physical weathering is as important as chemical weathering, and running water is the most important geomorphic force. In the natural state, the process of landform evolution is much slower than that in cold or arid areas.
Therefore, the ancient landforms formed during the Pleistocene period have been completely preserved. But this is just the general situation. In this area, the climate on the east coast of the mainland is different from that on the west coast of the mainland, and the Mediterranean climate is somewhat unique.
