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.
Obesity is associated with a long list of adult health conditions, including heart disease, high blood pressure and strokes, type 2 diabetes, various types of cancer, and psychological and social problems. Obese children are likely to be obese into adulthood. In 2006/2007, the age-standardised obesity prevalence rate for the population aged 15 years and over was 25 percent. This was similar to the 2002/2003 rate of 24 percent but a significant increase from the 1997 rate of 19 percent.
