The autumn in the Southern Hemisphere occurs when Earth is at H. position 3 on its orbit . Therefore , H. position 3 is correct .
Autumn in the Southern Hemisphere occurs when the South Pole is tilted away from the Sun, receiving less direct sunlight.
This happens between the autumnal equinox (around March 20 or 21) and the winter solstice (around June 20 or 21).
Looking at the diagram, we can see that the South Pole is tilted away from the Sun at position 3.
Therefore, autumn in the Southern Hemisphere occurs when Earth is at position 3 on its orbit.
Here's a breakdown of the other positions:
Position 1: The South Pole is tilted towards the Sun, receiving more direct sunlight.
This would be summer in the Southern Hemisphere.
Position 2: The Sun is directly overhead the equator, and neither pole is tilted towards or away from it.
This would be the spring or fall equinox, depending on the hemisphere.
Position 4: The North Pole is tilted away from the Sun, receiving less direct sunlight.
This would be winter in the Northern Hemisphere.
