(2012江苏卷)图5是某地地形剖面及其地下同一沉积岩层埋藏深度示意图。岩层的埋藏深度(岩层距离地面的垂直距离)可以用来帮助恢复岩层的形态。读图回答9~10题。9.属于背斜谷的地方是()A.12 B.23C.34 D.14此题考查地貌形态及地质构造的判断。首先从地形上看四地均是谷地地形,那么到底哪个才是背斜呢?大部分学生没有理解“同一沉积岩层埋藏深度线”的问题,只是单纯地根据该深度线的 (2012 Jiangsu Vol.) Figure 5 is a schematic diagram of the buried depth of a certain terrain profile and its subterranean sedimentary strata. The burial depth of the rock formation (the vertical distance between the rock formation and the ground) can be used to help restore the rock formation. Figure read answer 9 ~ 10 questions. 9. Belongs to the anticline valley () A.12 B.23C.34 D.14 This question examines the morphology and geological structure of the judgment. First of all, from the topography, all four places are valley terrains, so which one is the anticline? Most of the students do not understand the problem of “buried depth line of the same sedimentary layer ”, simply based on the depth of the line
