<h3>What is geology? </h3>

Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.

In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.

According to the previous process, it can be inferred that the missing layers in each column are:

Column 1: Layers 3 and 8 are missing.
Column 2: Layers 1 and 7 are missing.
Column 3: Layers 1 and 5 are missing.
