high energy interrelationship of landforms Flashcards

1
Q

shore platforms and cliffs

A

when cliffs are eroded - retreat occurs - shore platform - due to tidal range - seasick bay - 400m long - 500m wide

horizontal bedded strata

Q

how is interrelationship showED

A

as for a shore platform to be formed a cliff must be eroded

different rock types will alter speed of retreat

Q

Headlands and CASS

A

headlands such as flambourough head (chalk) - haves waves hitting the headland - have large energy due to 1500km fetch

Q

wave refraction

A

waves are refracted due to friction - therefore exert more of their energy on the headland - leads to CASS formation - green stacks pinnacle

Q

what is needed for headlands and bays to form

A

must be a variation in geology - discordant coastline - robin hoods bay (shale formed in jurassic period) - ravansgvr (sandstone - porous water enters cracks)

Q

differences in retreat

A

wouldn’t form if shale of robin hoods bay didn’t retreat at 0.8m a year - while ravansgvr retreats at 0.1m a year
