WHAT CAUSES DAY AND NIGHT ON EARTH? AT THE EQUATOR EARTH ROTATES AT A SPEED OF 1600 KPH (KILOMETERS PER HOUR) IT TAKES EARTH 24 HOURS TO ROTATE ONCE ON ITS AXIS SO THE AMOUNT OF TIME ON EARTH TAKES TO COMPLETE ONE ROTATION IS A DAY,ONE ROTATION ONE DAY 24 HOURS LONG GOT IT? AS EARTH ROTATES PART OF IT FACES THE SUN AND THE OTHER DOES NOT MAKING THAT SIDE NIGHT AND THE PART FACING THE SUN DAY, SO IF IT TAKE THE EARTH TO ROTATE ON ITS AXIS IN 24 HOURS THERE WOULD BE 12 HOURS DAY AND 12 HOURS NIGHT , FROM SUNRISE TO SUNSET GOT THAT? A YEAR ON EARTH IS 365.26 DAYS WOWIE! IT SURE DOESNT FEEL LIKE THAT MANY DAYS BUT I GUESS IT WOULD TAKE THAT LONG TO MAKE A COMPLETE ROTATION AROUND THE ENORMOUS SUN, HOW ENORMOUS 1.35 KILOMETERS IN DIAMETER , 1 MILLION EARTHS COULD FIT INSIDE IT,BUT IF YOU THINK THE SUN IS HOLLOW OH BOY YOU WRONG THERE IS FOUR LAYERS OF THIS BIG BALL OF HOT BURNING GAS WHICH THEY ARE CALLED THE CORE WHICH IS THE CENTER OF THE SUN,THE PHOTOSPHERE WHICH IS THE INNERMOST LAYER ,THE CHROMOSPHERE WHICH IS THE LAYER BELOW THE CORONA,AND LAST BUT NOT LEAST THE CORONA THE OUTERMOST LAYER OF THE SUN.
YOU MIGHT KNOW OF THE AURORA WHICH IS BANDS OF SHIMMERING COLORED LIGHT WHICH IS CAUSED BY SOLAR WIND PARTICLES AND THE PARTICLES FROM THE SUN COLLIDING WITH THE EARTHS MAGNETOSPHERE MAKING A BEAUTIFUL DANCE OF LIGHTS.GALILEO GALILEI WAS THE FIRST PERSON TO LOOK AT THE MOON WITH HIS TELESCOPE,HE SAW HIGHLANDS, MOUNTAIN RANGES ON THE MOON,HE SAW BROAD LOWLAND PLAINS WHICH HE CALLED MARIA A LATIN WORD FOR SEAS SINCE HE THOUGHT IT WAS WATER THE DARK AREAS HE SEEN.HE ALSO SAW RILLES -ACTIVE VOLCANOES ,OR LONG VALLEYS.
