DOUBLE Jeopardy Why do spring tides have higher bulges on Earth than all other tides?
Spring tides occur only during the new or full moon phase. The sun, moon, and Earth must be all lined up in a straight line. The pull of the sun's and moon's gravity on Earth is at its strongest and tides bulge out at their highest. Don't go into the ocean during High Tide!!
