Which tide occurs during a full or new moon and is characterized by an extra-high tide caused by the straight-line arrangement of the sun, moon, and earth? a. low b. neap c. spring

c. spring. When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.
