Explanation

Climate zones depend on latitude and other factors. Tropical: warm year-round, heavy rainfall. Temperate: four seasons, moderate conditions. Polar: extremely cold, little precipitation.

Nigeria has tropical climate types: equatorial (southern, high rainfall), tropical savanna (middle belt, wet/dry seasons), sahel (northern, semi-arid).

Factors affecting climate: latitude, altitude, distance from sea, ocean currents, prevailing winds, mountain barriers. These create local variations within zones.
