Amazing rock formations

I have traveled to many beaches in this world and not only do I love beaches for there white powdery sand and the blue turquoise waters the other feature that I love and find attractive and fascinating is the seascape formations the cliff sides, small rocks, big boulders and every beach has it's own distinguishing formations of rocks which draws my attention.

What really fascinates me most about beach rocks is why are they so different on every beach of the world I assume this could be put down to the history of the geological events that have taken place over the millions of years over the beaches of the world.
