Tout d'abord, la Terre tourne autour du Soleil \u00e0 une vitesse de 30 km\/s, soit 45 fois plus vite que le Concorde. Il lui faut 365 jours (une ann\u00e9e) pour effectuer une orbite compl\u00e8te autour du Soleil.<\/p>\n<\/div>\n<p>Elle tourne \u00e9galement tr\u00e8s vite, comme une toupie pench\u00e9e d\u2019un c\u00f4t\u00e9. Les personnes vivant \u00e0 l\u2019\u00e9quateur se d\u00e9placent d\u2019ouest en est \u00e0 une vitesse de 1 670 km\/h. (Cette vitesse est inf\u00e9rieure pour celles vivant pr\u00e8s des p\u00f4les.) Comme tout ce qui nous entoure se d\u00e9place de la m\u00eame mani\u00e8re, nous ne remarquons g\u00e9n\u00e9ralement pas la vitesse \u00e9lev\u00e9e \u00e0 laquelle nous nous d\u00e9pla\u00e7ons. Le moyen le plus \u00e9vident de s'en rendre compte est d'observer le Soleil, la Lune et les \u00e9toiles qui semblent se d\u00e9placer dans le ciel.<\/p>\n<p>L'inclinaison de l'axe qui relie les p\u00f4les Nord et Sud explique l'existence des saisons sur Terre. Lorsque le p\u00f4le Nord est tourn\u00e9 vers le Soleil, c'est l'\u00e9t\u00e9 dans les pays du Nord. Lorsque le p\u00f4le Nord est d\u00e9tourn\u00e9 du Soleil, ces pays connaissent l'hiver.
