Spits
A spit is an extended stretch of
beach material that projects out
to sea and is joined to the
mainland at one end.
SPIT
HOW ARE THEY
FORMED?
Back to Agenda Page
Spits are formed where the
prevailing wind blows at an angle to
the coastline, resulting in longshore
drift. An example of a spit is Spurn
Head, found along the Holderness
coast in Humberside.

STAGES OF
FORMATION
Stages of Formation:
Sediment is transported by
longshore drift
Where the coastline changes
direction, a shallow, sheltered area
allows for deposition of sediment
Due to increased friction, more
deposition occurs
Eventually, a spit slowly builds up
to sea level and extends in length
Back to Agenda Page
If the wind changes direction,
then the wave pattern alters
and results in a hooked end
The area behind the spit
becomes sheltered
Silts are deposited here to
form salt marshes or mud
flats
FACTORS THAT
AFFECT FORMATION
Back to Agenda Page
Spits are eroded by the sea and wind but a constant supply of sediment from
longshore drift ensures their continued existence. Events such as storms change
the shape of a spit drastically over short periods of time though. During a storm
event, erosion exceeds deposition so a lot of material is removed from the spit,
changing its shape.
