Ans: A spit which is also usually known as sandspit is a deposition bar of a beach formed by the re-entrance of the water from the water bodies. They are usually composed of sand or shingle and are mostly formed because of the longshore movement of the sediments. They have a curved feature that is complex in nature along with a recurved hear or hook which is a characteristic part of the spit. This happens because of the refraction of the waves around the spit from the re-entrance of the water from the water bodies back into the land.
