Final answer:
The tilt of Earth's axis causes seasonal variations in sunlight exposure, influencing global climate patterns.
Explanation:
The tilt of the Earth's axis is the primary factor influencing the different climatic seasons in the Northern and Southern Hemispheres. During summer, the hemisphere tilted towards the Sun experiences warmer weather due to more direct sunlight, while the opposite occurs in winter.
As the Earth orbits the Sun, the angle of sunlight changes, affecting the intensity of solar energy reaching different regions. This variation in sunlight exposure results in the different seasons experienced globally.
Changes in Earth's orbit and the intensity of sunlight from the Sun over time have historically impacted Earth's climate, leading to phenomena like ice ages and interglacial periods.
