4. Raised Beaches - that have never met the sea.

Science is a way of thinking much more than a body of knowledge. - Carl Sagan


Synopsis

A raised beach, marine terrace, or perched coastline is an emergent coastal landform. Raised beaches and terraces are beaches or wave-cut platforms high above the current shore line relative to a fall in the sea level.  These are clearly seen in area such as Norway or Scotland where the ice cap has compressed and sunk the ground surface layer (Isostatic Transformation) and has over thousands of years rebounded back to its original height.

One of the classic cases of these ‘Raised Beaches’ is on the South Coast of Britain between Bournemouth and Brighton.  Unfortunately, an ice cap has never reached these areas during the last half a million years, although the raised beaches are sitting just 18” below the top soil. Theories of how this sandy layer that appears in the soil layers high in hill sediments are abundant, including British tsunamis.


So is there a more sensible answer to the fact that sand is seen 30m above the current sea level and what does that tell us about the environment of the recent past we did not know until now?
