Question

Compare neap and spring tides. Give two comparisons in your answer.

Spring tides occur approximately twice a month, when the earth and moon and sun are about co-linear. That is about at full moon and about at new moon.
Neap tides occur at half moons, when the moon is off to the side of the line between earth and sun.
