The word climate comes from the Greek word klima for slope referring to the angle of the sun and the climate zones it creates. (drtimball.com)
The ancient Greeks called this tilt klima, literally «slope,» «inclination.» (merriam-webster.com)
Because the angle is determined by your latitude, klima came to mean «latitude,» and the earth was divided into seven latitudinal regions, called klimata. (merriam-webster.com)
