18,000 years ago, the central Cyclades were one island, whereas today they are separated. This could have happened because:
of river and/or rain inundation over the years.
of continental rifting that divided the initial island into many lesser ones.
of eustatic sea-level rise due to glacier melting.
the central (i.e. planar) part of the initial island was eroded.
The processes that led to the formation of this Naxian tafoni could be:
aeolian erosion
corrosion (chemical solution)
wave erosion
bioerosion (erosion through organisms)
development of salt crystals
Would you describe these sand dunes as stabilized?
Yes, because there is scarce vegetation and the sand is not eroded by the roots.
No, because there is scarce vegetation and it cannot restrain the sand grains.
No, because they are very close to the beach and the sand will therefore be eroded by wave activity.
No, because sand dunes are dynamic landforms.
How did this tombolo form?
It was a large sandy peninsula and it was eroded through wave activity and this spit is what remained.
It was the boundary of a lagoon, a part of which was eroded and/or inundated, thus this spit remained.
It formed as sand was deposited through waves and/or currents.
It was excavated and/or the sand was removed by humans.
How would you describe the landform in the center of the picture?
As a beachrock, formed through the cementation of the palaeo-beach, which was linear but was tectonically folded afterwards.
As a beachrock, formed through the cementation of the palaeo-beach, which bended because there was a river delta, offering the beach sediment.
As a beachrock, formed through the cementation of the palaeo-beach, which was connected to an adjacent island through a palaeo-tombolo.
It was constructed by humans.
How did this coastal cliff form?
Through wave erosion.
Through splash (rain) erosion.
Through landfalls/landslides.
Through glacial erosion.
Why is this beachrock submerged?
It formed underneath the sea-level.
It formed underneath the bottom sediments and was later exposed.
It is not a beachrock, but a rock which fell from the adjacent mountain.
It formed at the sea-level and was inundated.
These are two maps of a site of Naxos, 6,000 years ago (left) and today (right). How could this difference be explained?
The area was embanked through sediments transported from an adjacent river.
The area was uplifted and the initial bay disappeared and was rendered inland.
The area was embanked through sediments transported from waves and/or currents.
The area was later filled with sediment artificially (from humans).
How did this notch form?
It was created in this position through bioerosion by marine organisms
It was initially created near the sea-level by wave erosion and was later submerged.
It was initially created near the sea-level by bioerosion and was later submerged.
It is a palaeo-surface on top of which the overlying sediments were deposited.
Which coastal feature/features protect the coastal zone from flooding due to sea level rise at Naxos?
Beachrocks
Sand dunes
Lagoons
