A barrier bar which gets keyed up to the headland of a bay is called a spit. A spit is a coastal landform. This article will briefly cover some interesting aspects of the Spit landform.

• There will be a gradual extension of spits, bars, and barriers at the mouth of the bay.
• This gradual extension will only leave a small opening of the bay into the sea.
• A lagoon will eventually be developed from the bay.
• There are possibilities of spits developing attached to hills or headlands.

Waves Building Spits (Landforms)

• When the gently sloping sedimentary coast gets hit by waves, the sediments at the bottom get churned thereby helping to build spits, lagoons, and barrier bars.
• Eventually, a lagoon will be formed when spits and barrier bars are formed at the mouth of a bay.
• Barrier bars and waves are important for the formation of a bay.
• Bars are long ridges of sand and/or shingle parallel to the coast in the nearshore zone.
• When bars show up above the water, they are called barrier bars. Bars are usually submerged features.
