Explanation:

The gently sloping accumulation of coarse alluvial deposits by the braided stream is known as a sand bar. • A sandbar is a portion of sand, gravel or fine sediment that sits above the water. It may be get connected to the shoreline, or it may be offshore. It is usually narrow and straight. A sandbar is also called as a shoal or a sandbank. A large sandbar is also called a barrier island. • Sandbars begin forming underwater. As the waves break, this attracts material from the shoreline, migrating even further into the ocean. During the time of heavy storms, large waves can build sandbars far from the shore, until they rise above the water's surface. Sandbar Landforms Have 3 Main Characteristics: • Made of sand, silt or gravel • Formed by the wave action and currents • Generally forms the straight line Famous Sandbars (or Barrier Islands): • Miami Beach, Florida, USA • Bolivar Island, Texas, USA
