what conditions are required for sand dune formation?correct answers -a large flat beach -a large supply of sand formed by constructive waves -a large tidal range so sand has time to dry -onshore wind to move sand to the back of the beach - prevailing winds (strong and fast enough) -an obstacle such as driftwood for the dune to form against characteristics/ nature of sand dunescorrect answers •Coastal dunes are accumulations of sand •This sand is shaped into mounds b...

Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. - AnswerThe more times the wave is passing through a point in space = a higher frequency, the higher frequency creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has the highest frequency and the shortest distance between waves, the velocity can be measured in m/s and is composed of frequency and wavelength Calculate any one (frequency, wavelength, or velocity) given the...
