Why do spring tides happen? When there is a new and full moon, the gravitational pull of the sun is supplemented to the gravitational pull of the moon on Earth. The result of this is that the oceans swell even more than usual. Therefore, there's an increase in the height of high tide – which is what a spring tide is.
Cassie is writing an equation to show the effect of gravitational pull of the sun and moon on tidal range which equation would Cassie use to show the effect of the sun and the moon on Spring tides?
A - sun + moon = spring tides
B - sun + Earth = spring tides
C - moon - sun = spring tides
D - earth - moon = spring tides
