Artificial mothers' milk (formula) is very expensive. Every day you nurse is another day you haven't paid for formula. When women nurse, the same hormones that cause milk to flow acts as a natural tranquilizer, keeping them mellow in the face of all that baby stress. Nurse a year and your baby will be less susceptible to allergies, less likely to need braces, and well nourished.
The deeper the water, the greater the speed of tsunami waves will be. For example, at the deepest ocean depths the tsunami wave speed will be as much as 800 km/h, about the same as that of a jet aircraft. Since the average depth of the Pacific ocean is 4000 m (14,000 feet) , tsunami wave speed will average about 200 m/s or over 700 km/h (500 mph).
What do tsunamis travel at a speed of? 500 miles an hour; about as fast as a jet airplane; they can cross the entire expanse of the pacific ocean in less than a day What happens to tsunamis as they approach the shoreline?
