If the air temperature is low enough to keep the precipitation frozen, it falls as lake-effect snow. For lake-effect rain or snow to form, the air moving across the lake must be significantly cooler than the surface air (which is likely to be near the temperature of the water surface).
Major Health Problems Associated with Childhood ObesityCauses of obesity in children: Physical Activity: Lack of physical activity and a sedentary lifestyle are major contributors to obesity. Low physical activity in children may also be associated with a higher risk of developing cardiovascular disease.
Behavioral Factors. Because the factors that contribute to childhood obesity interact with each other, it is not possible to specify one behavior as the âcauseâ of obesity. However, certain behaviors can be identified as potentially contributing to an energy imbalance and, consequently, to obesity.
