Answer:
seasons
Step-by-step explanation:
Earth's tilt causes opposite seasons in the Northern and Southern Hemispheres. The Northern Hemisphere experiences summer when it is tilted towards the Sun, and winter when it is tilted away from it. Conversely, the Southern Hemisphere has winter when it is tilted towards the Sun, and summer when it is tilted away from it. This phenomenon is known as the seasonal change in the hemisphere's climate.
