In the geological field, stratum is a term used to list the layers that a rock formation can have, as a product of years of sedimentation. Most of the rocks that have these peculiar characteristics are within the group of metamorphic, sedimentary and pyroclastic rocks, which differ from the rest because they are formed from other materials, whose origin is not directly with the new creation, such as mineral remains, settled sediment or volcanic ash, respectively. At first glance, you can see how the passage of time has significantly modified the structure of the stone, which has different shades throughout, ranging from the lightest brown to gray with a slight touch of blue.

Sediment, on the other hand, is all the material that is in movement on the earth’s surface and it is almost always a portion that belonged to a rock or some earth, which, due to the effect of some climatic factor, began a long journey. After a while, it takes some stability and is deposited on an area that enjoys great solidity, such as a rock formation, and later, over the centuries, it finally becomes part of where it decided to settle.

The water currents likewise, are an important part of the sedimentation process, because in places where before there were somewhat strong liquid courses, it can be seen how it attracted different waste that settled over time, creating some sedimentary rocks. . However, the word stratum can also refer to the social status that a person belongs to, which is influenced by their economic production capacity.
