Latitude and longitude make up the grid system that helps humans identify absolute, or exact, locations on the Earth's surface. There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. Latitude affects the amount of solar radiation a place receives. The amount of solar radiation a place receives is greatest at the equator and lessens toward the poles. Latitude is not the only factor that determines the temperature of a region.
