Homonym: strata (Layers)
Strata refers to layers of material, often found in geological formations. These layers can be made up of different types of rock, soil, or sediment, and they provide important information about the Earth's history. For example, when scientists study strata, they can learn about past climates, natural events, and the evolution of life on Earth.
In addition to geology, the term "strata" is also used in other fields, such as sociology and education. In sociology, it describes the different levels of social hierarchy, like class or status. In education, it can refer to various levels of learning, helping to organize students based on their skills or knowledge.
