Answer:
1.Human migration involves the movement of people from one place to another with intentions of settling, permanently or temporarily, at a new location.
2.Emigrate means you are exiting your current homeland:
People are always saying there's no quality of life in Russia, and everyone wants to emigrate," he said. (New York Times)
Immigrate means you are coming in to a country to live:
Citizens from 17 European Union countries were given freedom to immigrate to Switzerland in 2007. (Business Week)
4.long, high sea wave caused by an earthquake or other disturbance.
5.Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate. That vibration pushes the adjoining piece of ground and causes it to vibrate, and thus the energy travels out from the earthquake hypocenter in a wave.
