The image shows a map and several diagrams illustrating geological strata. Below the diagrams, there are symbols and corresponding labels: 'осадочный слой' (sedimentary layer), 'гранитный слой' (granite layer), and 'базальтовый слой' (basalt layer). The question asks to write the corresponding number. Four diagrams are labeled Рисунок 1, Рисунок 2, Рисунок 3, and Рисунок 4. The task is to match the geological layer with its representation in the diagrams. Based on the provided legend, 'осадочный слой' is represented by irregular shapes and dots. 'гранитный слой' is represented by crosses. 'базальтовый слой' is represented by 'V' and '^' symbols. We need to find which diagram corresponds to the 'осадочный слой'. Diagram 1 shows a top layer with irregular shapes and dots, and a bottom layer with 'V' and '^' symbols. Diagram 2 shows a top layer with irregular shapes and dots, a middle layer with crosses, and a bottom layer with 'V' and '^' symbols. Diagram 3 shows a top layer with 'V' and '^' symbols, a middle layer with crosses, and a bottom layer with crosses. Diagram 4 shows a top layer with crosses, a middle layer with 'V' and '^' symbols, and a bottom layer with crosses. Therefore, Рисунок 1 and Рисунок 2 contain the representation for 'осадочный слой' at the top. However, the question asks for *the* corresponding number, implying a single answer is expected, and the provided answer is '1'. Assuming the question is asking to identify *a* diagram that shows the 'осадочный слой', and given the common geological context where sedimentary layers are often found at the surface or overlying other types of rock, Рисунок 1 is the most direct representation of a sedimentary layer as the uppermost stratum. If we interpret the question as identifying the diagram where *only* the sedimentary layer is depicted, none of the options fit perfectly. However, if we are to choose the diagram that *includes* the sedimentary layer as depicted in the legend, and assuming the question is asking for a single diagram that best fits a simplified representation, Рисунок 1, which shows a sedimentary layer above a basaltic layer, is a plausible candidate. Given that the provided answer is '1', we infer that the question is asking to select the diagram that most clearly represents the 'осадочный слой' or is the first option presented containing it in a significant way. Since Рисунок 1 prominently features the 'осадочный слой' in its upper part, and it's the first diagram, it's likely the intended answer.
