Sandbar
Context
A long, narrow sandbank, especially at the mouth of a river
Explanation
A sandbar, also known as a shoal or sandbank, is a landform made of sand, gravel, or silt, created by the action of tides, currents, waves, or wind. Sandbars form at river mouths, along coasts, and in bodies of water.
Applications
The sandbar was exposed during low tide, creating a temporary walkway to the island.
Sandbars can change the shape of coastlines and create habitats for marine life.
Boaters must be cautious of sandbars to avoid grounding.
