How Beaches Are Formed

Why Do Some Beaches Have Rocks Instead Of Sand?

Beaches are a highly desired attraction for vacations or holidays and with good reason! Beaches are vast gateways to some of the most gorgeous views of the ocean.

From the crisp sands, vibrant shades of blues and greens, and lush backdrops of vegetation, beaches certainly offer a remarkable visit.

With such iconic views, it leads to the curiosity of how beaches are actually formed. Nature can be a mystery, however, when it comes to how beaches are created, there is some insight!

Formation Of Beaches

Most beaches are formed by waves or currents washing up sand, rocks and other sediments onto shorelines of outer-lying parts of continents. This process is more than just waves or currents carrying these items onto shorelines worldwide. In fact, the process is quite fascinating!

The formation of beaches dates back millions of years. This extremely dated process has helped to give a base for beaches to continually be changed and reformed. While this is not always seen by the naked eye, beaches are constantly everchanging.

In areas like Australia for example, its preliminary beach fronts were formed when it broke away from Antarctica. Once that happened, Australia, specifically the NSW area, gained astronomical amounts of debris from mountain areas on Antarctica.

It is said that floods of melted ice from this area made its way to the shorelines of NSW Australia.

In regards to basic beach formation, sand can be made of quartz, corals, rocks, seashell pieces, etc.

All of these are deposits brought forth to shorelines carried through the ocean and pushed ashore by strong waves.

The motion of these waves and the miles upon miles that these deposits may have travelled results in smoothed edges.

This is particularly true for quartz beaches which are considered to be perfectly sized and soft to the touch.

Moreover, the constant movement of the ocean and its various waves are what make these deposits truly unique. It makes for no single piece to appear exactly the same.

When looking at a beach from this perspective, their immersive beauty even more stunning.

It is commonly believed that what a beach is made from helps identify the region in which that beach is located. Geological speaking, these materials can travel from miles and miles away, however, it can be from region-specific sediments.

Once again, it all really boils down to these sediments becoming smooth enough to create these sands along the shorelines.

How Are Pebble Beaches Formed?

Overall, no matter what beach sand is comprised of, the process in which it is formed is pretty standard. However, pebble beaches are distinctively formed a little differently.

Pebbles, in general, are usually extremely smooth in texture. This is obviously similar to how all beaches are made as the pebbles roll around within the constant movement of waves and tides. This action in itself aids in making the textures slick and smooth.

What really sets pebble beaches apart from regular beaches is where the sediments originate. When waves crash into large cliff sides, falling pieces are captures in the waters.

These pieces go through erosion and an extreme break down to create the small, smooth pebbles.

Even more idyllically, these pebbles are continuously ground down into finer and finer pieces as they travel along the waters. This creates smooth, tiny pebbles that wash up along shorelines.

It is incredible to think that ocean waves and tides can be strong enough to break off chunks of these cliffs.

This truly gives insight into how remarkable pebble beaches are as well as other types of beaches.

Various Coloured Sand Beaches

The deposits that wash up along shorelines to form beaches can come in so many different colours. These colours are the result of the material in which the sand derived from.

Some beaches even have multi-coloured sands creating such a rainbow of beauty.

When assessing these gorgeous colours, knowing their overall origins helps put their colours into perspective. Below are the top colours that can be found in beaches all over the world!

  • White – This colour is generally quartz and limestone
  • Light-Coloured – Typically derived from quartz and iron
  • White (in tropical areas) – This colour is made up from finely ground seashell pieces which are usually made of calcium carbonate.
  • Pink – This pale peachy pink colour comes from calcium carbonate that is primarily mixed with coral pieces.
  • Black – This colour on a beach is not too common, but is from volcanic rock. These types of beaches are unique in their own way.
  • Red – Red is also considered volcanic rock sediment. However, it is moreover considered iron that has been oxidized.
  • Orange – This vibrant colouring is usually a mixture of seashells, orange limestone, iron, and even volcanic rocks.
  • Green – It may seem absurd that some beach fronts have green sands, but it does occur. These sanded shores are believed to be made of olivine. This particular coloured beach forms from eroded volcanic forces.

These colours are found worldwide and really make for tremendously beautiful beaches. The specific colouring makes them unique and as expressed before, relative to their particular regions.

Beaches: No Two Are Alike

No two beaches will ever be exactly the same. Moreover, beaches all over the world are in a constant state of change. The waves and tides consistently crashed upon the shorelines keeps the shape and overall look of beaches always appear slightly different.

While this may not be immediately noticed by a general glance, it can be noticed throughout many years of this activity. When people take a trip to beach fronts, their experience in witnessing these natural forms of art is breath-taking.

The ever-changing shorelines around the world along continents are mobile, moving pieces of art. It will continuously be a way that shorelines become even more gorgeous beachfront areas.

Perhaps this is what attracts people to beaches all around the world for vacations or holidays. Whether people notice or not, their eyes are beholding these works of natural art be formed.

Spending time on the beach gives way to experiencing this as well as enjoying the tranquil and picturesque atmospheres that beaches truly provide its visitors!
