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.
From 6 months through 1 year old, infants inhale and exhale 25 to 40 times a minute. Toddlers between 1 and 3 breathe 20 to 30 times a minute. The normal respiratory rate for 6- to 12-year-olds is 14 to 22.
