Burrow (geological)

A burrow, in geological terms, refers to a tunnel or hole created by animals in the ground, often for shelter or nesting. These structures can reveal much about past ecosystems and environmental conditions, as they provide insights into the behaviors of the animals that made them. Burrows can vary in size and complexity, and they are typically found in soil, sediment, or rock. They play an important role in soil aeration and nutrient cycling, and they can also serve as habitats for other organisms. Understanding burrows helps scientists study biodiversity and the interactions within ecosystems.
