هل توجد جبال على كواكب أخرى (Info)
أول ما فعله العلماء، لكي يعرفوا الكواكب المحيطة بنا، هو أن يراقبوها بالمنظار الفلكي ثم ارسلو أقمارا صناعية لتصورها، بل توصلوا إلى جعل الإنسان يمشي على سطح القمر. نري، على عدد كبير الكواكب، مرتفعات تشكل غالبا دوائر كبيرة. إنها جوانب الفجوات التي أحدثتها صخور ضخمة هي الجوه أو النيازك، حين سقطت على على سطحها من الفضاء. الواقع ان جبال الكواكب لا تشبه نفع جبال الأرض.
