3.  Spit is a long narrow ridges of sand and shingle which
is projected into the sea from coastline

4.  Longshore drift transports material along the coastline
 Spits formed in shallow and sheltered water when
there is a change in the direction of the coastline
 Deposition occurs resulting in the accumulation of
sand and shingle
 The material initially deposited is the largest
material, dropped due to the reduction in energy

5.  Finer material is then deposited, helping to build up
the rest of the spit
 As spit grow outwards, a change in wind direction may
result in a change in the direction of the spit forming a
curved end (recurved laterals)
 If growing across a river estuary, the length of the spit
will be restricted
 A salt marsh may form in the sheltered, low energy
zone behind the spit.

7.  a ridge of sand and shingle joining the mainland to an
island

8.  Tombolo's are created through the process of
longshore drift
 A tombolo is formed where the spit continues to
grow until it reaches an island, forming a link with
the mainland, just like bridges

10.  a ridge of sand and shingle which has joined two
headlands, cutting off a bay

11.  (a) a spit grows the whole way across a bay
(b) a sandbank devlops offshore, parallel to the
shore, and is moved towards the coastline by the
waves and wind until it joins the mainland
 Behind the bar, a lagoon is created, where water has
been trapped and the lagoon may gradually be infilled
as a salt marsh
 Over time the lagoon will become infilled by
deposition

Summary
Tombolos Bars
What is it? a ridge of sand and a ridge of sand and
a ridge of sand and
shingle projecting shingle joining the
shingle which has
from the mainland mainland to an joined two
into the sea island headlands, cutting
off a bay
How does it form? when there is a formed when spit (a)form when a
break in the continue to grow spit grows the
coastline and drop outwards whole way across a
in energy, long- connecting the bay
shore drift mainland to the (b) a sandbank
deposited the offshore island just develops offshore,
material and build like bridges parallel to the
up spit shore until it joins
the mainland
