Answer:
In the Southern Hemisphere, the spring season begins. There is also an increase in temperature when the North Pole is tilted away from the sun.
Step-by-step explanation:
Season formation of the planet earth is dependent on tilting. Tilting doesn’t occur in some planets, which corresponds to absence of seasons. Regions which are directly exposed to the radiation of the sun have warmer climate while the regions which are away from the direct sun radiation have a cold climate.
When tilting occurs, these cold regions expose to direct sunlight and spring season is started which leads to summer season.
