Question

The range of the tides is affected by the relative positions of the sun and the moon. During the new moon and full moon, the highest high tides and the lowest low tides occur. During the first and third quarters of the lunar month, the lowest high tides and highest low tides occur. Throughout the month, the tidal range gradually increases and decreases between the minimum and maximum values of the range. • Sketch a graph of a tidal range as a function of time, showing what you think the shape of a tidal cycle might look like for one month.
