Read the following materials and complete the related questions. Material 1: Look at the topographic map of the United States and the climate type map of a certain place. Material 2: northeastern United States

(1) North temperate zone, between 30 N and 50° N in most parts of the United States.

(2) Southwest direction

(3) The plain area is vast, the soil is fertile, the water is abundant, and the climate is warm and humid (2 points is enough for correct answer).

(4) The cold and humid climate is conducive to the growth of succulents; The consumer market is vast. Deep inland, dry and little rain.

(5) The Central Plains runs through the north and south, and the cold air from the north can drive south.

(6)C

Test analysis:

(1) Most of the United States lies between the Tropic of Cancer and the Arctic Circle, so most of the United States lies in the north temperate zone among the five zones.

(2) The United Nations headquarters is located in new york, and Virginia and West Virginia are in the southwest of the United Nations headquarters.

(3) The favorable conditions for agricultural development in the United States are: the Great Lakes and the Mississippi River have convenient water transportation and fertile plains; Flat terrain and abundant water resources.

(4) The development condition of dairy industry is that the climate is cold and humid, which is conducive to the growth of succulent forage; The consumer market is vast. The reason for developing irrigated agriculture is to live in the deep inland and the climate is dry and rainy.

(5) Because the terrain of the United States is high in the east and low in the middle, cold air can go south in winter, which often leads to cold weather along the Mexican coast in winter.

(6) According to the analysis of temperature curve and precipitation histogram in the figure, the climate type in this area is Mediterranean climate, which is distributed on the west coast of the mainland. So this question chooses option C.

Comments: There are tall mountains in the west of North America, and the water vapor in the Pacific Ocean is not easy to penetrate eastward. The low mountains and plateaus in the east will not block the water vapor from the Atlantic Ocean. Therefore, the precipitation in North America mainly comes from the Atlantic Ocean, with the annual precipitation decreasing from east to west and increasing year by year along the Pacific coast. Central plains of North America, with gentle north and south. Cold air from the north may push south in winter, and warm air from the south may push north in summer, thus raising the temperature in North America and aggravating the continental characteristics of the climate in North America.
