Lowland refers to a portion of the Earth's surface that is predominantly flat and lies at a lower altitude compared to its surrounding areas. These regions can be found all over the world and are commonly characterized by their extensive plains, fertile soil, and suitability for agriculture and settlement. The term encompasses a variety of landscapes including valleys, basins, and floodplains. Lowlands are significant for human habitation due to their accessibility, ease of transportation, and resource availability. Additionally, they often play a critical role in the ecology and hydrology of an area, serving as areas for drainage, water retention, and biodiversity.
