জলমণ্ডল

জলমণ্ডল (গ্ৰীক শব্দ: হাইড্ৰ’, “জল” আৰু স্পাইৰা, “মণ্ডল”) হৈছে ভূ-পৃষ্ঠত থকা সকলো সাগৰ-মহাসাগৰ, হ্ৰদ, নদ-নদী, ভূ-জল, অন্যান্য জলৰাশি, জলীয় বাষ্প আনকি গোটা অৱস্থাত থকা বৰফ, এই আটাইবোৰক একেলগে জলমণ্ডল বোলে। জলমণ্ডলে পৃথিৱীৰ পৃষ্ঠৰ প্ৰায় ৭১ শতাংশ ঠাই আগুৰি আছে। পৃথিৱীৰ জলমণ্ডল প্ৰায় ৪ বিলিয়ন বছৰ ধৰি বৰ্তি আছে। ^[1]^[2] মহাদেশীয় বিস্থাপন আৰু সমুদ্ৰতল প্ৰসাৰণৰ বাবে ইয়াৰ আকৃতি সঘনাই সলনি হৈ থাকে।^[3] বিশেষকৈ গোলকীয় উষ্ণতা বৃদ্ধিৰ বাবে বৰ্তমান পৃথিবীৰ জলমণ্ডলৰ আকৃতি দ্ৰুত গতিত পৰিবৰ্তন হ’বলৈ ধৰিছে।^[4]
