potential influences on coastal landscape systems of wind

Question 1

what is wind the source of energy for?

Answer 1

source of energy for coastal erosion and transportation
(speed, direction, frequency)

Question 2

what is the energy of a wave dependent on?

Answer 2

the energy of a wave is dependent on the strength of the wind, its duration and the length of the fetch –> the longer the fetch the greater the energy

Question 3

how does wind strength varying make a difference globally?

Answer 3

wind strength and duration varies around the world - therefore wave energy also varies

Question 4

what do many coastlines have?

Answer 4

they have a prevailing (most common) wind direction

Question 5

equation for power of a wave?

Answer 5

P=H2 T
tells us that wave height is most important in determining wave energy

Question 6

where does wind energy dominate?

Answer 6

in dune environments

Question 7

what are onshore winds effective at?

Answer 7

onshore winds blowing from the sea towards the land are effective at driving waves towards the coast

Question 8

do winds create waves?

Answer 8

yes because of its frictional drag
