| [實用空中美語寫法] Auroras form high above Earth's surface.They occur when various gases in the atmosphere are stimulated by surges of solar energy.These powerful bursts of energy from the sun,called "the solar wind," are attracted to Earth's magnetic field.This magnetic field is strongest around the poles,which is why auroras are most clearly seen from places like Alaska,Greenland,and Antarctica. 我的寫法 Auroras form above the Earth's surface because various gases in the atmosphere are stimulated by the solar wind,the powerful bursts of energy from the sun,are attracted to the Earth's magnetic field. The magnetic field is the strongest around the pole,that is why auroras are most clearly seen near the polar region,like Alaska,Greenland,Fairbanks. |
