The origin of these rhyolite complexes is still not well-understood. Many folks think that Yellowstone, for example, is associated with a hotspot. However, a hotspot origin for most other rhyolite calderas doesn't work; they occur in subduction-related arcs. Examples of rhyolite caldera complexes include Yellowstone, La Primavera, Rabaul, Taupo, Toba, and others.
Average respiratory range by age is given below: 1  Newborns â Average 44 breaths per minute. 2  Infants â 20-40 breaths per minute. 3  Pre school children â 20-30 breaths per minute.  Older children â 16-25 breaths per 1  minute. Adults â 12-20 breaths per minute.  Adults during strenuous exercise â 35-45 breaths per minute.
Children have faster respiratory rates than adults, and the normal respiratory rate can vary significantly by age. The normal ranges of respiratory rates for children of different ages include: Newborn: 30-60 breaths per minute. Infant (1 to 12 months): 30-60 breaths per minute. Toddler (1-2 years): 24-40 breaths per minute. Preschooler (3-5 years): 22-34 breaths per minute.
