جزيرة جرينلاند

جزيرة جرينلاند تعتبر أكبر جزيرة في العالم، مساحتها 21,66,086كم². وهذا في حالة إستبعدنا أستراليا كونها كتلة قارية. وتمثل أحد أقاليم الدنمارك على الرغم من أنها تعد جغرافيًا جزءً من أمريكا الشمالية. تقع على بعد 2,090كم شمالي المحيط الأطلسي. وتبعد في بعض أجزائها نحو 16 كم من كندا. وتعد جرينلاند أكبر من الدنمارك بحوالي 50 مرة، ولكن الدنمارك تفوق جرينلاند في عدد السكان بحوالي 95 مرة.

كتلة جليدية متحركة في سكوريسبي صند شرق جرينلاد, وهو أكبر خلل في العالم.

تتكون أراضي جرينلاند من هضبة داخلية منخفضة تحيط بها جبال ساحلية وتغطي طبقة جليد دائمة ما يعادل 1,740,500كم² أو حوالي أربعة أخماس مساحة الجزيرة. ويتراوح سُمْك الغطاء الجليدي ما بين 1,6كم و3,2كم. يبلغ ارتفاع جبل جنبجورن أعلى نقطة في جرينلاند 3,700م، ويقع شرقي الغطاء الجليدي. وتوجد آلاف الجزر بعيدًا عن الشاطئ. وتقطع مئات الفيوردات على الساحل بين الجبال وتمتد إلى الداخل، وتنساب المثالج من الغطاء الجليدي منحدرة عبر الأودية الداخلية مكونة جبالاً جليدية ضخمة تتحطم وتتلاشى في الفيوردات
