Sources of energy: Wind Flashcards
wind is a …………….source of energy in the coastal systems as………………………………………..
primary source as it drives other processes
wind is not only a source of energy, but also
an important agent of erosion and transportation
another way of looking at wind is a
spatial variation in energy
where wind speeds are persistently high and uninterrupted, wave energy is likely to be
higher
most coastlines will have a
prevailing wind direction
the prevailing wind controls
the directions that waves approach the coastline and also the direction of transport of material in the coastline
waves are created from the
wind blowing over the sea surface
the wind blowing over the sea surface is called
frictional drag
the energy acquired by waves depends on: (3 items)
- fetch
- wind strength
- length of time the wind blows for
wind acts as an agent of erosion because
it can pick up and remove sediment from the coast, which is then used to erode other features
abrasion is when
material picked up by the wind is used to erode other features by the wearing out of landscape features
