wave formation
Cards (2)
- the sun has direct influence on wave formation
- how are waves formed?
- wind moves across water surface - frictional drag
- circular orbital motion of water particles in ocean
- seabed becomes shallower towards coast
- orbit of water becomes elliptical - horizontal movement of waves
- wave heigh increases
- wavelength and velocity decrease
- water backs up behind wave
- wave breaks and surges up beach
