This process also releases oxygen to the air. In theropod dinosaurs carnivores that walked on two legs and had birdlike feet flexible soft tissue air sacs likely pumped air through the stiff lungs, as is the case in birds.

Since the temper- ature increases with depth in the Earth, the conductiv- ity is higher with increasing depth. Christopher Clark discovered how male hummingbirds use aerodynamics to generate sounds with tail feathers during courting displays. We find where damage has occurred and where pristine waters and land must be protected.
