(1) warm front? Continuous precipitation

(2) folding? Synclinal valley? The top is under tension and is often eroded into valleys?

3) Party A and Party C

(4) Anticline B has strong bearing capacity and stable lithology due to its arched structure, and is not easy to leak (65438+ 0 for any two answers).

Test analysis:

Question (1), this little question examines the relevant knowledge of the weather system. In the picture, the warm air mass is strong and the cold air mass gradually recedes, so it can be judged that this weather system is a warm front system. Under the control of warm front, cloudy days and continuous precipitation often occur in B.

Question (2), this small question examines the relevant knowledge of geological structure. In the figure, the strata are bent and deformed, forming folds. The original rock in the first place bends downward to form a syncline, and the original rock in the second place arches upward to form an anticline, and the top of the anticline is easily eroded into a valley under the action of tension.

Question (3), this small question examines the geographical significance of geological structures. Anticline is an oil storage structure; Among A, B and C, B is anticline, which often becomes a good oil storage structure. Syncline is a water storage structure; A, b and c, where b and c are water storage synclines.

Question (4), this small question examines the application of geological structure. Because of its arch structure, anticline has strong bearing capacity, stable lithology and is not easy to leak, so it is suitable for building underground tunnels. A, b, c and d have only b anticline structure.

Comments: This question is more difficult. Put the knowledge about geological structure and weather system in the same picture to test students' comprehensive analysis ability. To solve this problem, it is necessary to make it clear that (1) rock strata bend and deform, forming folds. There are two basic forms of folds: anticline and syncline. The anticline rocks arch upward to form mountains; Syncline rocks bend downward to form valleys. The top of anticline is easy to be eroded into valleys by stretching, while the trough of syncline is difficult to be eroded into mountains by squeezing. (2) The anticline is an oil storage structure and the syncline is a water storage structure, so the construction of tunnels, reservoirs and large-scale projects should try to avoid faults. (3) There are three weather systems: cold front system, warm front system and quasi-static front system. To know the difference between these three weather systems, make a good knowledge reserve for answering questions in the future.
