The correct statement regarding the relationship between the new moon, full moon, and spring tides is:
These phases indicate that the Earth, Moon, and Sun are aligned, combining the Moon's and Sun's gravity on Earth's tides.
During the new moon and full moon phases, the Earth, Moon, and Sun are in alignment. This alignment results in the combined gravitational pull of the Moon and the Sun on the Earth's oceans, leading to higher high tides and lower low tides, which are referred to as spring tides. Spring tides occur approximately every two weeks, during the full moon and new moon phases.
