Question

How are beaches formed ?

Answer 1

Hint:
A beach is a landform with a body of water that contains loose particles. The particles that compose a beach are usually made of rock, such as sand, gravel, shingles, pebbles, etc., or biological sources, such as mollusk shells or coralline algae. Sediment is disposed of at different densities and structures depending on local waveform and weather, creating different textures and colors and gradients or layers of material.

Complete answer:
Although some beaches are formed at freshwater locations, most breaches occur in coastal areas where ripple or current action accumulates and sediments occur. The erosion and alteration of beach geology occurs through natural processes, such as wave action and extreme weather events. Where the wind conditions are correct, the beaches can be supported by coastal dunes that provide protection and uplift for the coastline. However, these natural forces have become more extreme due to climate change, changing the beaches at very rapid rates. Some estimates suggest that 50 percent of Earth's sandy beaches disappeared by 2100 due to sea level rise due to climate change.
These beaches are popular for recreation, playing an important economic and cultural role - often running local tourism industries. They may also have hospitality sites (such as resorts, camps, hotels and restaurants) for both permanent and seasonal residents nearby or in residence.
Human forces have significantly altered beaches globally: direct impacts include dunes and poor construction work on the beach, while indirect human impacts include water pollution, plastic pollution, and sea level rise and climate. Changes include coastal erosion. Some coastal management practices are designed to preserve or restore natural beach processes, while some beaches are actively restored through practices such as beach nourishment.

Note:
Wild beaches, also known as undeveloped or undiscovered beaches, are not developed for tourism or recreation. Protected beaches are significant biomes with vital roles in aquatic or marine biodiversity, like breeding grounds or ocean areas for ocean turtles or nesting areas for penguins. Protected beaches and their associated dunes are significant for protection from extreme weather for upcountry ecosystems and human infrastructure.
