Answer :
Final answer:
During the spring and autumnal equinoxes, both of Earth's hemispheres receive an equal amount of energy from the sun due to the Earth's axis position. These equinoxes signify the times when neither hemisphere is tilted toward or away from the Sun.
Explanation:
Both Hemispheres Receiving Equal Sunlight
The Northern and Southern Hemispheres receive the same amount of energy from the sun during the spring equinox and the autumnal equinox. During these times, the Earth's axis is in a position where neither hemisphere is tilted toward or away from the Sun, resulting in both hemispheres receiving equal amounts of sunlight.
Explanation of Equinoxes
- During the spring equinox on March 21st, the Sun is perpendicular to the equator, illuminating both hemispheres equally.
- Similarly, during the autumnal equinox on September 23rd, the same phenomenon occurs, leading to equal distribution of sunlight to both hemispheres.
