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).
On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds (the same amount of time), then the speed of this ocean wave is 2.5 m/s. The faster wave travels a greater distance in the same amount of time.
