A beach is a geographical formation made up of loose sediments, such as sand, gravel or pebbles, located along the coastline. It can be washed by oceans, seas, lakes or rivers and is subject to natural processes such as erosion, sedimentation and tidal action.
In addition to their ecological importance, beaches play a central role in tourism, water sports and coastal culture, and are essential to the economy of many regions.
Main characteristics of beaches
✔ Location: Encontram-se em zonas litorais, podendo ser oceânicas ou fluviais. ✔ Composition: Can vary between fine sand, gravel, rocks, shells, and algae. ✔ Formation: Result of wind, tides, and sediment transport over time. ✔ Biodiversity: Habitat for coastal birds, fish, and other marine organisms.
Types of Beaches
| Type of Beach | Characteristics | Examples |
|---|---|---|
| Sandy | Predominantly fine or coarse sand | Praia da Rocha, Algarve |
| Rocky | Composed of rocks and cliffs, usually less accessible | Praia da Ursa, Sintra |
| Fluvial | Located along rivers or lakes, with fine sediments | Praia Fluvial do Penedo Furado |
| Reef Beach | Found near coral reefs, common in tropical regions | Beaches of the Madeira Archipelago |
🔹 Beaches can also be natural or artificial, depending on the origin of their sediments and maintenance processes.
