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).
* A tsunami is a series of waves with a long wavelength and period (time between crests) generated by a large, impulsive displacement of sea water. * Time between crests of the wave can vary from a few minutes to over an hour, but generally are in the range of 15 to 30 minutes. The most common cause of a tsunami is sea floor uplift associated with an earthquake. * Tsunamis are also triggered by landslides into or under the water surface, and can be generated by volcanic activity and meteorite impacts.
