Which of the following is not an element of climate?

Fog is not an element of climate. Climate refers to the long-term patterns of weather in a particular region, while fog is a short-term weather event that can occur in any climate. Fog is caused by the cooling of moist air, which causes water droplets to form and become suspended in the air. While fog can be influenced by climate factors such as temperature and humidity, it is not considered an element of climate itself. Rather, it is a specific type of weather event that can occur in a range of climates.
