Examples of rhyolite caldera complexes include Yellowstone, La Primavera, Rabaul, Taupo, Toba, and others.

A normal respiratory rate is termed eupnea, an increased respiratory rate is termed tachypnea and a lower-than-normal respiratory rate is termed bradypnea. Breathing (which in organisms with lungs is called ventilation and includes inhalation and exhalation) is a part of respiration. normal respiratory rate is termed eupnea, an increased respiratory rate is termed tachypnea and a lower-than-normal respiratory rate is termed bradypnea.
