THE PLANET WHICH IS CALLED EARTH

THE THIRD PLANET WHICH IS 9,29,33,OOO MILES AWAY FROM SUN ,ROTATES AROUND ITSELF AS WELL AS REVOLVES AROUND THE SUN.

THE EARTH COMPLETES ONE ROTATION IN ABOUT 24 HOURS ,FROM THE POINT OF VIEW OF THE SUN.

THE EARTH REVOLVES AROUND THE SUN IN APPROXIMATELY 365DAYS WHICH COMPOSES ONE CALENDER YEAR.

ROTATION OF THE EARTHTHE EARTH’S ROTATION IS THE ROTATION OF THE SOLID EARTH ITS OWN AXIS . THE EARTH ROTATES TOWARDS THE EAST. AS VIEWED FROM THE NORTH STAR POLARIS , THE EARTH ROTATES COUNTER- CLOCKWISE.

THE GEOGRAPHIC NORTH POLE OR TERRESTRIAL NORTH POLE , IS THE POINT IN NORTHERN HEMISPHERE WHERE THE EARTH’S AXIS OF ROTATION MEETS ITS SURFACE . THIS POINT IS DISTINCT FROM THE EARTH’S NORTH MAGNETIC POLE . THE SOUTH POLE IS THE OTHERPOINT WHERE THE EARTH’S AXIS OF ROTATION INTERSECTS ITS SUFACE, IN ANTARTICA .

THE EARTH ROTATES ONCE IN ABOUT 24 HOURS IN THE POINT OF VIEW FROM THE SUN AND ONCE IN 23 HOURS 56 MINUTES 4 SECONDS FROM THE POINT OF VIEW FROM THE STARS.

REVOLUTION OF EARTH AROUND THE SUN

THE EARTH’S ORBIT IS THE OF THE EARTH AROUND THE SUN FROM AN AVERAGE DISTANCE OF APPROXIMATELY 150 MILLION KMs .

VIEWED FROM A VANTAGE POINT ABOVE THE NORTH POLES OF BOTH THE SUNAND THE EARTH, THE EARTH WUOLD APPEAR TO REVOLVE IN A COUNTER-CLOCKWISE DIRECTION ABOUT THE SUN . FROM THE SAME VANTAGE POINT BOTH THE EARTH AND THE SUN WOULD APPEAR TO ROTATE IN A COUNTER-CLOCKWISE DIRECTION ABOUT THEIR RESPECTIVE AXES.

EFFECTS OF MOTIONS OF EARTH

EFFECTS OF ROTATIONTHE ROTATION OF THE EARTH CAUSES DAY AND NIGHT . AS THE EARTH SPINS, ONE SIDE FACES THE SUN WHICH HAS DAY TIME WHEN THE OTHERSIDE NOT FACING THE SUN HAS NIGHT TIME.

THE REVOLUTION OF THE EARTH AROUND THE SUN CAUSES SEASONS. THROUGHOUT THE YEAR , AS OUR SMALL BLUE PLANET ORBITS THE SUN ,MANY PARTS OF THE EARTH EXPERIENCE CHANGING SEASONS SUCH AS : WARM SPRING HOT SUMMER PLEASANT AUTUMN COLD WINTER
