Au cours de cette p\u00e9riode, on observe et on ressent des changements : par exemple, les journ\u00e9es sont plus courtes ou plus longues, et les temp\u00e9ratures sont plus \u00e9lev\u00e9es ou plus basses.\u00a0 Ces cycles r\u00e9currents des conditions m\u00e9t\u00e9orologiques sur Terre s\u2019appellent les saisons. Mais saviez-vous que nous vivons des saisons diff\u00e9rentes en fonction de la quantit\u00e9 de lumi\u00e8re solaire que nous recevons ? La lumi\u00e8re solaire est plus concentr\u00e9e \u00e0 certains endroits qu\u2019\u00e0 d\u2019autres, ce qui explique pourquoi certains endroits sont plus chauds que d\u2019autres \u00e0 diff\u00e9rentes p\u00e9riodes de l\u2019ann\u00e9e.<\/p>\n<p>Tout en tournant autour du Soleil, la Terre effectue \u00e9galement une rotation sur elle-m\u00eame toutes les 24 heures ! C'est cette rotation qui est \u00e0 l'origine de l'alternance du jour et de la nuit sur Terre. \u201c Une journ\u00e9e \u2019 correspond en r\u00e9alit\u00e9 au temps que met la Terre pour effectuer une rotation compl\u00e8te autour de son axe et englobe \u00e0 la fois le jour et la nuit !<\/p>\n<\/div>\n<h2>Regarder<\/h2>\n<p>D\u00e9couvrons ensemble comment la Terre interagit avec le Soleil :\u00a0<\/p>\n<figure class=\"wp-block-embed is-type-video\"><iframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/TagG32gwiBo\" title=\"Lecteur vid\u00e9o YouTube\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/figure>\n<h2>Quiz<\/h2>\n<figure class=\"wp-block-embed is-type-video\"><iframe src=\"https:\/\/paxigames.esa.int\/Games\/Trivia\/trivia.html?lan=en&#038;topic=13\" width=\"900\" height=\"500\" scrolling=\"no \"allowfullscreen=\"true\" webkitallowfullscreen=\"true\" mozallowfullscreen=\"true\" ><\/iframe><\/figure>","protected":false},"excerpt":{"rendered":"<p>The Earth takes 365 days, 1 whole year, to complete one orbit around the Sun!
