Latitude Affects Temperature. One of the primary factors affecting the unequal heating of the Earthâs atmosphere is latitude. Latitude is the measurement of the distance of a location on the Earth from the equator. The further away from the equator that a location resides, the less sunlight that this location receives.
Temperature Extremes. Earth's surface temperature depends on how much energy it receives from the sun. The equator, which is in direct sunlight all year, tends to be the hottest place, but the highest air temperature ever recorded was at Death Valley, California, in 1913.It was 56.7 degrees Celsius (134 degree Fahrenheit).ts average surface temperature is following a warming trend. In 2013, Earth's average temperature was 14.6 degrees Celsius (58.3 degrees Fahrenheit), according to NASA.
