There is a constant flow of sand from the land into the ocean. Watershed run-off and bluff and hillside erosion bring sand to the beach. Sand grains travel southward down the coast, while finer particles of sediment are carried and deposited further out to sea.
Along the way, sand is washed ashore, temporarily resting on beaches, until it is re-suspended in the ocean by wave action or wind. The one-way journey down the coast ends when sand is blown inland forming sand dunes, or more commonly, when it flows into a submarine canyon. This deep underwater feature is essentially the dead end of a littoral cell, where sand is deposited for the long-term and, for practical purposes, lost.
Littoral Cell
A littoral cell is a distinct area of the coastline where sand enters the ocean, flows down the coast, and then is removed from the system. Permanent loss of sand occurs at the end of the littoral cell when it flows into a submarine canyon or, less frequently, when it accumulates on shore as part of a sand dune. The amount of sand available to beaches is the amount of sand flowing into the littoral cell minus the amount flowing out. If this sand budget is altered, beaches can narrow or even disappear.

Seasonal Change
Southern California beaches undergo dramatic seasonal change due to a shift in wave energy. High-energy winter storm waves pull sand offshore, creating more narrow, cobbled beaches. Lower, gentle summer waves carry sand onshore, widening beaches.

Beach erosion (coastal erosion) is the process that takes place in the coastal areas. This process refers to the removal of the sand particles and are carried towards the sea. It is caused mainly due to the occurrence of storms, movement of sea water currents and tidal effect. It leads to the formation of narrow beach and lowers its elevation.
Some of the ways by which the beach erosion can be reduced are, by covering the areas with vegetation, by constructing seawalls, sandbags and setting up sand fences. Natural and artificial sand dunes can also prevent beach erosion.
In other societies education can be harder to get because not all people can afford and have schools. And others still use like hitting hands with rulers for punishment instead of detention, suspension, etc.
I live in the Republic of Macedonia, Tikvesh area, town of Negotino. The area that falls in the borders of the municipality in which I live has climate that is very variable. The summers are heavily influenced by the Mediterranean climate, so they are hot and dry, the winters are heavily influenced by the continental air masses, so they are cold and dry, while the spring and autumn are moderate and are also the rainiest periods of the year. The precipitations varies a lot from year to year, and it can be anywhere from 250 to 750 mm. The landscape is dominated by a valley, naturally being a grassland, but now heavily used for agriculture, mostly wine trees. The eastern side is bordered by a mountain of slightly over 1,000 m, while the southern part is bordered by a volcanic plateau. The population is slightly more than 20,000, and it has been like that for around two decades now. The main reason why there haven't been significant changes is that the birthrates have dropped, while the life expectancy has increased, so the population is gradually aging.
In this description I have used three geographic themes, location, human/environment interactions, and place.
