Shoals are raised landforms made of sand and gravel that are commonly found in Florida. They are often called sandbars and are located in and around bodies of water such as oceans, rivers, and lakes. Which factor most commonly causes shoals to form or change shape?

Formation. Wave shoaling is the process when surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling, and the waves are said to shoal.

Heavy rain fall causes shoals to form and change shape creating depressions and bars in the sand
