Formações are geological features that result from the deposition of sediment over time. They are typically characterized by their layered structure, which reflects the gradual accumulation of materials such as sand, silt, and clay. These layers, known as strata, can provide valuable insights into the Earth's history, including past climates, environments, and the presence of ancient life.

Formações can vary significantly in size and composition. Some are relatively small and localized, while others span vast areas and are composed of diverse materials. They can be found in various settings, including deserts, coastal regions, and river valleys. The study of formações is crucial for understanding the processes that shape the Earth's surface and for identifying potential resources such as water, minerals, and fossil fuels.

The term "formação" is commonly used in Brazil and other Portuguese-speaking countries to describe these geological features. In English, they are often referred to as formations or sedimentary sequences. The study of formações is a key aspect of geology, contributing to our understanding of the Earth's past and present.
