Tropical

Tropics

The tropics are the region of Earth surrounding the equator, where the Sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. Because of Earth's axial tilt, the width of the tropics is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone.
