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 earths axis is tilted at the maximum

Explanation:

• Option A: Ocean tides are related to the moon's and sun's gravitational pull, not equinoxes. Eliminate A.
• Option B: Lunar eclipses occur when the Earth is between the sun and moon, unrelated to equinoxes. Eliminate B.
• Option C: Equinoxes (spring and autumn) happen when the sun is directly over the equator, marking the start of new seasons (spring and autumn), so they signify a change in seasons.
• Option D: Lunar phases are due to the moon's position relative to Earth and sun, not equinoxes. Eliminate D.
• Option E: Earth's axis tilt maximum is related to solstices, not equinoxes. Eliminate E.

Answer:

C. a change in the seasons
