Prevailing winds and pressure belts are major climate controls. A belt of low pressure known as the intertropical convergence zone (ITCZ) lies along the Equator. On either side of the equatorial low, between 25Â° and 30Â° latitude in each hemisphere, is a belt of high-pressure centers over the oceans. From the equatorial side of these subtropical highssuch as the Hawaiian high.
The normal breathing rate for a 4 month old baby is between 30 and 60 breaths per minute.
Groups of children Their ages Normal respiration rates Newborns and infants Up to 6 months old 30-60 breaths/min Infants 6 to 12 months old 24-30 breaths/min Toddlers and children 1 to 5 years old 20-30 breaths/min Children 6 to 12 years 12-20 breaths/min.ost modern adults breathe much faster (about 15-20 breaths per minute) than their normal breathing frequency. The respiratory rates in the sick persons are usually higher, generally about 20 breaths/min or more.
