The chalk was deeply frozen and in the short summer defrosts the surface layer of snow and partly defrosted chalk would slump under gravity to lower levels. As the glaciers went into retreat from the English Midlands, and as more snow water was released, rivers, and then sea level rose. The Channel formed as we know it about 9, — 8, years ago and Britain was separated from European mainland.
Marine activity swirled away the chalky muds of the channel area and left the flint debris behind. Currents and wave activity gradually rounded the flints into sub-angular pebbles. Currents and storm conditions drove some of this ashore as a fringe to wave activity, leaving a large quantity in the deep channel. It does not move either side of high water. It all ends up at Dungeness eventually.
There is a worrying finding by Sussex University geographers which has become apparent recently, and that is the fact that the shingle is a decreasing resource and that rising sea levels on the south coast, linked to increased storm activity, and dwindling shingle, means a bleak time ahead for coastal dwellers.
Geoffrey Mead, sent to website mailing-list, At last! I have always thought that the pebbles were the result of erosion caused my nature, even as a boy. Some people think that they were put there by man but can you just imagine the man power and machinery needed for such a task! Even now you can see the pebbles embedded in the cliff face and from time to time there is collapse of the cliff face. The sea is a fantastic and conniving force both strong and immense.
I lived by the sea until I was 21, in Eastbourne and saw what the sea can do. In winter, if there was a particularly rough sea, it would empty many beaches of pebbles and sand, right down to either the hard pack sand or the baserock. The ramps going down to the beaches would have their foundations exposed, also the promenade foundations too, it was a great time to go beach hunting as well. Then the next day all the pebbles returned as if nothing had happened. Sometimes the sea would wash tons of pebbles up onto the lower promenade and council workers had to shovel them by hand out of the shelters and back onto the beach.
It is definitely a natural occurrence, the sea is able to sort out different size pebbles and very often you will get a mixture of coarse sand and small pebbles at the half tide mark. Councils spend thousands of pounds installing groynes and repairing them to stem the flow of pebbles easterly which should prove the fact that the sea moves them and could deposit pebbles in an obstructive way in just one area if left to its own devices.
That is how Pevensey Levels were formed, by the longshore drift of pebbles east to west. Pevensey marshes were originally under water until the flow of pebbles cut the sea off when the penisula extended all the way to Bexhill. The pebbles along the Sussex shoreline are During the five ice ages we have had over the past two million years the Downs were covered in deep snow for thousands of years; there is no evidence of glaciation further south than North London.
This poured south and north off the chalk. That to the south eventually was covered by the rising waters of the melted snows and about 10, years ago the Channel formed. The flints are rolled by the currents and are rounded into pebbles, pushed ashore by wave action and moved generally west-east by longshore drift; very little actually comes from cliff falls. This is a non-renewable resource that is being relentlessly dredged offshore for industry and will eventually deplete our beaches, which is worrying as with global warming, sea levels along the south coast are rising, while we are geologically sinking.
Not a good combination! The tar which nestled unseen on the shingle until you found you were covered in it was from ships. Back in the day ships were allowed to flush the dregs of their empty fuel tanks out at sea which clumped together to form tar. Nowadays ships are not allowed to clean their tanks at sea any more, they must be cleaned in an enviromentally friendly way, usually at a harbour by a professional company.
Yes we remember the tar on the beach. We would stand up and lo and behold we would have a great clump of tar, with pebbles stuck in it stuck to our clothes or body! Mum would as stated in one of the other comments, get a load of butter and rub it on the tar to remove it. Just recently I had discussed this with my children and Grandchildren, they could not believe it. Checking out this site in Montrose, Victoria Australia, it brings many memories flooding back.
The section of the beach known as Cliff Beach is for naturists and clothes are strictly optional in this area. So, we threw the question open to the voters on Tripadvisor to make our decision for us and they said, Weymouth Beach in Weymouth Dorset. That beach offers 3 miles of soft sand fronting a very traditional British seaside town. Does Brighton in England have a sandy beach? Brighton beach in East Sussex, also known as London by the sea, is a guaranteed fun day out for sun-seekers and daytime drinkers and clubbers.

Because this cafe is positioned further away from the more bustling touristy part of Brighton city coast. This may be part of its charm And it is further west in a more tranquil part of the Brighton city shoreline. Does Brighton in England have a Sandy Beach?
