A sandbar is a natural formation made of sand that rises above the water level in rivers, lakes, or oceans. These structures are created by the movement of water, which deposits sand in specific areas, often shaped by currents and tides. Sandbars can be temporary or permanent, depending on environmental conditions.
Sandbars can serve as important habitats for various wildlife, including birds and marine species. They often provide a safe resting place for birds and can help protect shorelines from erosion. Additionally, sandbars can influence local navigation, sometimes creating challenges for boats and ships in shallow waters.
