The picture shows "a schematic diagram of the weather system and geological structures of a certain place." Read the picture and complete the following questions (10 points) (1) Place B is subject to &nbs...

(Unless otherwise noted, each blank is 1 point)

(1) Warm front? Continuous precipitation

(2 ) Fold? Syncline valley? The top is affected by tension and is often eroded into a valley?

(3) B, A, C

(4) B anticline because of its arched structure , strong load-bearing capacity, stable lithology, not easy to seep water, etc. (Any two points are worth 1 point)

Test question analysis:

Question (1) , this question tests the relevant knowledge of weather systems. In the picture, the warm air mass is strong and the cold air mass gradually retreats, which indicates that this weather system is a warm front system. Under the control of warm fronts, area B often experiences cloudy days and continuous precipitation.

Question (2), this question tests the relevant knowledge of geological structures. The rock layer in the picture bends and deforms, forming folds. The original rock layers at site A curve downward to form a syncline, while the original rock layers at site B arch upward to form an anticline. The top of the anticline is easily eroded into a valley due to tension.

Question (3), this question examines the geographical significance of geological structures. Anticlines are oil storage structures; among the three locations A, B, and C, location B is an anticline and often becomes a good oil storage structure. Syncline is a water storage structure; of the three locations A, B, and C, two of them, B and C, are synclines that are conducive to water storage.

Question (4), this question examines the application of geological structures. Because of its arched structure, the anticline has strong load-bearing capacity, stable lithology, and is not prone to water seepage, making it suitable for the construction of underground tunnels. There are four locations A, B, C and D. Only location B is an anticline structure.

Comments: This question is difficult. Integrate relevant knowledge about geological structures and weather systems into the same picture to test students' comprehensive analysis abilities. To answer this question, it is necessary to clarify: (1) The rock layer bends and deforms, forming folds. There are two basic forms of folds: anticline and syncline. Anticlinal rock layers arch upward to form mountains; syncline rock layers curve downward to form valleys. The top of the anticline is easily eroded into a valley due to tension, while the syncline trough has hard rock and is not easily eroded due to compression, but instead becomes a mountain. (2) Anticlines are oil storage structures, and synclines are water storage structures. Tunnels, reservoirs, and large-scale engineering construction should avoid faults as much as possible. (3) There are three main types of weather systems: cold front systems, warm front systems and quasi-stationary front systems. You must know the differences between these three weather systems and prepare knowledge for future answers.
