Answer:
The Earth is constantly changing its position with the sun as the Earth tilts in relation to the sun. This creates the differences in the seasons and the annual warming and cooling cycles of the Earth’s Northern and Southern Hemispheres.
Explanation:
- When the North Pole tilts most toward the sun, the Northern Hemisphere experiences summer.
- Spring and Autumn) occur midway on the Earth’s journey from winter to summer and from summer to winter.
- On March 20 or 21 of each year, the Earth reaches the vernal equinox, which marks the arrival of Spring in the north and Autumn in the south. The autumnal equinox occurs on September 22-23 and marks the arrival of Fall in the north and Spring in the south.
- When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, and this has nothing to do with how close or far the Earth gets to or away from the Sun in its orbit. It’s all because the Earth is tilted on its axis.
