une boule toujour en mouvement

La Terre fait un tour complet sur elle même en un jour ou 24 heures (‘ rotation)à la vitesse 1666 km/h .

En même temps , elle fait le tour du soleil  , dont elle est éloigné de  150 millions de kilomètres  , en une année   ou 365 jours ( révolution) , a la vitesse de 108  000km/ h .

Quand ( une de ses faces de la Terre est éclairée par le soleil  , il y fait jour .

La face opposées est alors opposée est alors plongées dans la nuit .

Comme la Terre tourne sur elle meme chacue endroits de la planète passe successivement du jour de la nuit.  emoticone
