Question

why are temperatures more moderate around the fall and spring equinoxes?
the angle at which earths axis tilts changes.
neither end of earths axis is tilted toward the sun.
the north end of earths axis is tilted toward the sun.
the earth briefly wobbles on its axis.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Earth's axial tilt angle is constant (about 23.5°), so this is incorrect.
• Option 2: During equinoxes, neither the North nor South Pole is tilted toward the Sun. This leads to more even distribution of solar energy across hemispheres, causing moderate temperatures. This is correct.
• Option 3: This describes solstices (e.g., summer solstice in Northern Hemisphere), not equinoxes, so incorrect.
• Option 4: Earth's axis doesn't "wobble" briefly during equinoxes; precession is a long - term wobble, so this is incorrect.

Answer:

B. Neither end of Earth's axis is tilted toward the Sun.
