كوكب الأرض

 

كوكبُ الأرضِ هو كوكبنا الجميلُ الذي نعيشُ عليه، والذي رزقنا الله به كلَّ سبلِ الحياةِ والمعيشةِ والرّاحةِ. فلنأخذ رحلةٌ بسيطةٌ لنتعرف على كوكبنا أكثر.

ما الذي يميز كوكب الأرض؟
الأرض هي المكان الوحيد المعروف بوجود حياة عليه في الكون، وذلك بسبب وجود غاز الأوزون في جو الأرض الذي يحمي الأحياء عليها من الأشعة فوق البنفسجية الضّارة، وأيضًا بسبب موقعها المتوسّط من الشّمس ممّا أدّى لتوفيرِ جوٍّ مناسبٍ للحياة.

 

ما شكل كوكب الأرض؟
جسمٌ كرويٌّ مفلطحٌ عند القطبين، ومنبعجٌ عند خطّ الاستواء.

 

أين تقع الأرض؟
كوكب الأرض هو ثالث كواكب المجموعة الشمسية بعدًا عن الشّمس بعد عطارد والزّهرة، وتبـُعد الأرض عن الشّمس نحو 150 مليون كيلومتر.

 

ما هو حجم الأرض ومساحتها؟ ومم يتكون سطحها؟
يقدر حجم الأرض بحوالي مليون متر مكعب ومساحتها بقرابة 510 مليون و100 ألف متر مربع. وتشكّل المياه نسبة 70% من سطحها، بينما مساحة اليابسة هي 30% فقط!

 

كم عدد أقمارها؟
للأرضِ قمرٌ واحدٌ يستمدُّ ضوءه من الشّمس ويدور حول الأرض دورانًا ثابتًا.

من أين أتت الفصول الأربعة على سطح الأرض؟
تدورُ الأرضُ حولَ الشّمس باستمرارٍ، وتتم دورتها الواحدة كل 365 يومًا وتسمّى هذه الدورة السنة الأرضيّة، ونتيجةً لاختلاف زاويةِ سقوطِ الشّمس على الأرض واختلاف الحرارة تنشأ الفصول الأربعة.

 

ما سر وجود الليل والنهار؟
للأرض أيضاً دوران حول نفسها من الغرب إلى الشّرق. وتستغرق كل دورةٍ 24 ساعة. فالجهة التي تكونُ مقابلةً للشّمس يصبحُ عندها نهارٌ والجهةُ الأخرى من الأرضِ تكون مظلمةً لعدمِ سقوطِ الشّمس عليها.
