Final answer:
The Equator has minimal seasonal temperature variation because it receives consistent direct sunlight throughout the year due to Earth's 23.5° axial tilt.
Step-by-step explanation:
The region around the Equator does not experience seasonal variation in temperature because the Sun shines directly overhead throughout the year. This phenomenon occurs due to the 23.5° axial tilt of the Earth, rather than the Earth's orbit around the Sun or its distance from the Sun. The inclination of Earth's axis means that equatorial regions receive a relatively constant amount of direct sunlight all year round, while regions farther from the Equator experience changing angles of sunlight, which causes seasonal changes in climate and temperature.
