concordant and discodant Flashcards
(7 cards)
concordant is ..
rocks run parallel to coast
what is a dalmation coast (concordant)
landscape floods due to sea level rise
leaves islands that run parallel to mainland
croatia
what is a haff coast (concordant)
islands made of unconsolidated material
sand and shingle
deposited parallel to coast
what is discondorant coast
rocks run at a right angle to coast
headlands (discondorant)
narrow land that projects into sea
resistant rocks erode at a slower rate
waves become more concentrated
high energy environment
bays (disondorant)
inlet of sea where land curves inwards
less resitant rock
lower energy level
high depostition leading to wide beaches
wave refraction (discondorant)
concentrates energy from waves onto headlands leading to further erosion
energy dissipates into bays leading to deposition
