Explanation Text About Aurora

An aurora (latin word means “sunrise”) is natural light display in the sky in the north or south poles caused by the collision of energetic charged particles with atoms in the high alti altitu tude de atmo atmosp sphe here re.. In the the no nort rthe hern rn lati latitu tude de,, the the effe effect ct is kn know own n as aurora  borealis  (  (aurora: the dawn goddess, borealis: north wind). hile in the Antarctic region, aurora australis australis.. They  illuminate the the effe effect ct is know known n as aurora illuminate the northern northern and southern southern hori!on as greenish glow or sometimes faint red, occasionally blue but most often in fluorescent green. Auroras can be seen at night because their light is not as strong as the light of the day "he aurora phenomenon occurs when the sun produces solar wind. #olar wind is a stream of electrons and protons which are released from the sun due to the high kinetic energy. "hese particles are charged and contain energy, which means they contribute to electricity. In other way, our planet is surrounded by a super$si!ed magnetic sheath whic wh ich h is usua usuall llyy call called ed the the %agn %agnet etic ic &ie &ield of the the 'art 'arth. h. #ome #ometi time mess this this sola solarr wind hits the the 'arth. 'arth. #ome of these charged particles particles lead to to the poles of the earth at a speed that keeps growing. "he collision between these particles and atoms present in the earths earths atmospher atmosphere, e, it releases releases the energy energy that causes causes the formation formation of colorful colorful auroras at the poles of the earth, which looks like a big circle around the pole. hy Aurora is only found in the earths poles "his is because the north and #outh *ole magnetic field is +ery strong compared to other regions. "he poles of this magnetic field pull the protons and electrons from the solar wind. #o the phenomenon is more common in the *olar egions. -owe+er, sometimes the Aurora can also appear at the top of the mountain in a tropical climate, but this phenomenon is etremely rare. Aurora phenomena ha+e been obser+ed on other planets than 'arth that ha+e a magnetic field, such as /upiter, #aturn and more recently %ars. It is belie+ed to be a widespread phenomenon in the #olar #ystem and beyond. 0. hat hat is aur auror ora a 'p 'pla lain in..
