At which lunar phase(s) are tides most pronounced (e. g., the highest high tides)? at which lunar phase(s) are tides most pronounced (e. g., the highest high tides)? both new and full moons first quarter full moon both first and third quarters new moon

At both new and full moons (lunar phases) the tides are most pronounced (for example, the highest high tides).

At both new and full moons

Explanation:

    Depending on the position of the two stars in relation to our planet, the tides have different behaviors. This is where the lunar phases come in. When the earth, moon and sun are aligned - or, as astronomers say, in opposition or conjunction - the gravitational pull of the latter two adds up, amplifying their effect on the sea mass.

    NEW MOON: When the Earth, the Moon, and the Sun align, the gravitational pull exerted by the two stars on the oceans adds to each other, generating sea currents that cause maximum sea level elevation toward this line. It is the time of the highest tides, called tides of sizigia or maximum

    FULL MOON: About two weeks after the New Moon, our satellite travels back to a position where it aligns with the sun and the earth. This combination brings a new wave of high tides. In Santos beaches, the sea level can rise around 1 meter in this period
