Which of the following correctly describes spring and neap tides?
Spring tides only occur during a full moon, neap tides only occur during a new moon.
Spring tides occur when the Earth, moon, and sun are in a straight line, while neap tides occur when the moon and sun form a ninety degree angle with the Earth.
Spring tides have less of a difference in its high and low tides compared to neap tides.
Spring tides cause high tides and neap tides cause low tides.
