Students of the geological faculty analyzed the geological structure profile shown in the figure. Establish the correspondence between the rock layers, designated by letters in the figure, and the geological eras to which their formation belongs: for each element of the first column, select the corresponding element from the second column. ROCK LAYERS A) A B) Б B) B Write the chosen digits in the table under the corresponding letters. Answer: A Б B

Solution:

• The image displays a geological profile with rock layers labeled A, Б, and B. These layers are associated with geological eras. By analyzing the strata, we can infer their relative ages. Layer B is the oldest, followed by layer A, and then layer Б is the youngest.
• Geological eras are typically ordered as follows: Proterozoic (oldest), Paleozoic, Mesozoic (younger).
• Therefore, we can match the layers to the eras:
• Layer B (oldest) corresponds to the Proterozoic era (2).
• Layer A corresponds to the Paleozoic era (3).
• Layer Б (youngest) corresponds to the Mesozoic era (1).
