Question

select the correct answer. what do the equinoxes signify?
a. a change in ocean tides
b. a partial lunar eclipse
c. a change in the seasons
d. a change in lunar phases
e. a period during which earth’s axis is tilted at the maximum

Explanation:

The question seems to be about what an equinox signifies. An equinox is when the Sun is directly above the equator, leading to nearly equal day and night globally, which is a change in seasons (spring and autumn equinoxes mark the start of those seasons). Option A is about ocean tides (tides relate to lunar/solar gravity, not equinox directly). Option B: Lunar eclipses are when Earth is between Sun and Moon, not equinox. Option D: Lunar phases are about Moon's position relative to Sun/Earth, not equinox. Option E: Earth's axial tilt maximum is solstice, not equinox. So the correct answer is C as equinoxes mark a change in seasons (start of spring or autumn).

Answer:

C. a change in the seasons
