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.
Other conditions can also cause secondary obesity. Childhood obesity occurs when children and adolescents are above the normal body weight for their age and height. Obese children are at risk for long-term problems such as diabetes, hypertension, thyroid problems, and high cholesterol.
