Glass deposits are found on shores, which are formed after broken glass is eroded by the ocean. Their sharp edges smoothen with time, resulting in rounded and smoothened surfaces. These are man-made in artificial environments that are specifically created in an urban setting by urban planners. With sand being the classic element of these beaches, many of us have fond memories of making sand castles in them.
The sand is formed from minerals and rocks, which break into tiny bits and pieces by tides and waves. These comprise entirely or mostly seashells, which are from dead animals like snails, crabs, and other crustaceans that are washed up on the shore by the waves.
Black sand beaches, found in places with volcanoes, are created from lava stone being broken down into sand. There are only four green sand beaches in world, in Norway, Ecuador, Guam and Hawaii. These are created by olivine crystals, a silicate mineral containing iron and magnesium. Other sand colours include pink, orange, and purple, all influenced by different local minerals. Rocky beaches occur where coastal cliffs erode and crumble into large rock deposits along the the shoreline, blocking the build up of smaller, sandy sediment.
Rocky beaches are areas of rich intertidal biodiversity. Due to their accessibility, they have been studied perhaps more than any other habitat in the field of marine ecology. A process known as zonation occurs along rocky shores where very distinct habitat zones emerge as a result of the various stages of tidal exposure along the shore. Across these zones, species include plankton, seaweed and algae, barnacles, limpets and sea anemones, as well as a wide array of organic matter brought in with the tides.

Theses beaches are typically the result of a glacial activity, where the pebbles are polished over time by waves and tides. The profile of shingle beaches are typically quite steep because of their porous nature.
Mudflats are formed when tides and rivers deposit mud, estuarine silts, and clay along the shoreline. The majority of mud is found within the intertidal zone. This means they are only exposed during low tide, making the mud quite wet and soft. In northern European countries, such as Netherlands and Germany, mudflat hiking is a popular activity where hikers capitalize on low tides to hike along the mud flats.
Many of the worlds mudflats exist in this region, however they are also found in Asia and North America. Perhaps the most unique of all locations for a beach are cities. Urban beaches are different from beaches that naturally occur in urban areas in that they are man-made beaches designed to simulate a beach experience.
Most urban beaches are built near water, but some are even built in parks or other urban areas completely isolated from any body of water. Photo by Benson Kua.

Historical Status When swimming season is over or when a beach's water quality data has not been updated frequently enough weekly it goes into historical status. Special Status We may manually set the status for a specific beach if we have concerns about the sampling protocol, if there is an emergency, if monitoring practices don't exist or have recently changed, or other reasons that render this site "special.
Red means the water at the site has water quality issues or there is an emergency. Grey means there is no current water quality information, the beach is under construction, there has been an event that has rendered water quality information unreliable or unavailable.

This breathtaking view of Maldives is something that people across the world flock to catch a glimpse of. The purple color of the sand is due to sand sediments, like unique minerals, surrounded by the beach. While sands usually comprise of quartz, at this beach the sand is saturated with garnets.
This further contributes to shades of purple in the sand. Note that not all the sand at Pfeiffer beach is purple. Like green sand beaches, there are patches of sands being non-purple in appearance. It is more likely for you to come across the purple color after a winter storm. At times, the color seems to be more pinkish or even greenish too. The sand is not the only attractive element of the beach. Climb on it, take photos, or witness the glorious sunset or sunrise from the top. The view it offers is indescribable!
The good part is that if you ever feel hungry at the beach, there are a couple of eateries nearby such as the Big Sur Deli and The Big Sur Bakery and Restaurant. They are located just a mile away on the south of the beach. It is common for beaches to wash up empty shells on the shores. However, there are beaches that wash up seashells in bulks. Commonly, beaches comprise of rock particles like grit, gravel, pebbles, sand, etc. However, very rare beaches are composed of intact, broken, or partially broken seashells.
There are only four such beaches in the entire world; the most famous of them all is the Shell Beach in Western Australia. This stunning white sandy beach consists of millions of small shells that can go up to 10 meters deep. On the upper side of the beach, numerous shells have clammed together to form types of large, solid conglomerations. Sanibel Island in Florida is another seashell beach that consists of large quantities of seashells. The beach also accommodates plenty of local shell shops where you can get shells of your choice.
There is also a museum — the Bailey-Matthews Shell Museum — that houses an impressive collection of seashells. Glass Beach in Fort Bragg, California , is one of the most popular sea glass beaches in the entire world. You will be surprised to know that this beach site was originally a water dump site where people would discard old appliances, glasses, and vehicles too. After years of discarding the trash, cleanup programs took the initiative to clean up the dumpster.
The waves of the ocean rolled and tumbled sleek and shiny pieces of glass that were created from broken glass and metallic bottles and tableware. A casual walk on this beach will instantly turn into a happening stroll as you will come across amazing sea glasses in gorgeous colors like amber, sea green, white, and brown.
The rarest sea glasses are the ones that boast turquoise, orange, yellow, black, teal, and gray. Rocky beaches are created by the eroding of coastal cliffs. These cliffs are crumbled into different sizes of rocks along the shoreline.
The buildup of large rocks prevents the formation of sandy beach sediments. It is nearly impossible to navigate rock beaches in a vehicle which is why they must be approached on foot. Nonetheless, these beaches make for an amazing picnic destination with your loved ones. The most astonishing rocky beach is the Giants Causeway Beach Ireland which is composed of volcanic rocks and lava in odd geometric shapes. Sea caves are worth the second glance. We are sure their majestic beauty must make you wonder how they got formed in the first place.
Basically, sea caves are created by the wave action of a lake or an ocean. They usually occur in almost every coastal area where the waves break against a rock cliff. The continuous striking of waves on the cliff makes the rock weaker.
Over time, these rocks begin to erode, causing humongous inland caving. Also known as a city beach, urban beaches are a man-made, artificial environment.
