Making the world better, one answer at a time. The federal civil service was created by an Act of Congress in 1871. It was done to prevent the extreme unfairness in the hiring practices for those who worked for the government.
Introduction. Earthquake waves are seismic waves that are created when energy builds up in rocks and they fracture. Scientists estimate there are several million earthquakes each year. Every earthquake produces P waves and S waves but only larger earthquakes produce Love waves and Rayleigh waves.
What is it? A tsunami, or seismic sea wave, is a series of destructive and very dangerous waves that result from earthquakes or other types of disturbances such as volcanic eruptions, meteorite impacts, and landslides. Its waves can get up to 30 m (100 ft) tall--or as high as a 10-story building.sunamis are extremely deadly and can't be predicted, so they are rarely caught on camera and you won't have much time to react when you spot the first wave coming in. They can wipe out an entire population of people and bring a city down to its knees.
