What are estuarises?

Answer 1

Estuaries are coastal areas where freshwater from rivers and streams meets and mixes with saltwater from the ocean. They are characterized by brackish water, which has a salinity level between that of freshwater and seawater. Estuaries serve as crucial habitats for a diverse range of wildlife, including fish, birds, and other organisms, and they play a vital role in nutrient cycling and water filtration. Additionally, they act as natural buffers against storms and erosion, providing protection for coastal regions.
