high energy and low energy coastlines Flashcards
what are high energy coastlines associated with?
more powerful waves
because high energy coastlines have more powerful waves - it occurs in areas where there is a, what kind of fetch?
large fetch
what kind of landforms in high energy coastlines?
rocky headlands and landforms
what kind of waves tend to occur in high energy coastlines?
destructive waves
why are high energy coasts often eroding?
rate of erosion exceeds the rate of deposition
what kind of waves do low energy coastlines have?
less powerful waves
where do waves in low energy coastlines occur?
in sheltered areas - where constructive waves waves prevail
what kind of areas are the low energy coasts?
fairly sandy
why are their landforms of deposition in low energy coasts?
deposition exceeds the rates of erosion
