Beach Desktop Wallpapers Biography

A beach is made of very small loose rock (sand) that gathers at the shore of a body of water. Beaches are created by waves or currents. The sand comes from erosion of rocks both far away from and near the water. Coral reefs are a major source of sand.

A beach's shape depends on how the waves move. Some waves move material up the beach, while others move it down the beach. On sandy beaches, the waves move sand away from the beach, making gentle slopes.

When the waves are not strong enough to move the sand away, the beach is steeper.

Crabs, insects, and birds feed on material left by the waves. Some small animals dig into the sand to get their food. Birds use beaches to nest, and sea turtles lay their eggs on ocean beaches. Sea grasses and other beach plants grow on areas of the beach and dunes where there is not much activity.

A beach is a landform along the shoreline of an ocean, sea, lake or river. It usually consists of loose particles which are often composed of rock, such as sand, gravel, shingle, pebbles or cobblestones. The particles comprising the beach are occasionally biological in origin, such as mollusc shells or coralline algae.

Wild beaches are beaches which do not have lifeguards or trappings of modernity nearby, such as resorts and hotels. They are sometimes called undeclared, undeveloped or undiscovered beaches. Wild beaches can be valued for their untouched beauty and preserved nature. They are most commonly found in less developed areas including, for example, parts of Puerto Rico, Thailand, the Philippines, and Indonesia. Bangladesh is the home of the world's longest natural sandy sea beach located at Cox's Bazar.

Beaches typically occur in areas along the coast where wave or current action deposits and reworks sediments.
