On the equator, day and night are almost equal all year round, with daytime and nighttime lasting about 12 hours. However, the further you go towards the poles, the more obvious the difference becomes. There are places in the polar regions where people have to live in continuous sunlight for months on end, a phenomenon called polar day. Conversely, there are times when the whole region is plunged into darkness for months on end, a phenomenon called polar night. It is this difference that creates diversity and uniqueness in the natural life as well as the human experience in each geographical area.<\/span><\/p>\n<p><b>\u00dd ngh\u0129a c\u1ee7a hi\u1ec7n t\u01b0\u1ee3ng ng\u00e0y v\u00e0 \u0111\u00eam<\/b><\/p>\n<p><b>The significance of day and night<\/b><\/p>\n<p><span style=\"font-weight: 400\">Ng\u00e0y v\u00e0 \u0111\u00eam kh\u00f4ng ch\u1ec9 mang \u0111\u1ebfn s\u1ef1 thay \u0111\u1ed5i c\u1ea3nh quan thi\u00ean nhi\u00ean, m\u00e0 c\u00f2n gi\u00fap c\u01a1 th\u1ec3 con ng\u01b0\u1eddi duy tr\u00ec <\/span><b>nh\u1ecbp sinh h\u1ecdc t\u1ef1 nhi\u00ean<\/b><span style=\"font-weight: 400\">.

During the day, we work, study, and engage in activities; at night, we rest and restore our energy. In addition, the alternation of day and night helps regulate the Earth\u2019s temperature, creating a stable living environment for all species. Without day and night, our planet would become harsh and difficult to sustain life as it does today. This is truly a miraculous gift from nature that keeps life balanced and complete.<\/span><\/p>\n<p><a href=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-scaled.jpg\"><img decoding=\"async\" class=\"size-full wp-image-27497 aligncenter\" src=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-scaled.jpg\" alt=\"\" width=\"2560\" height=\"1707\" srcset=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-scaled.jpg 2560w, https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-300x200.jpg 300w, https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-1024x683.jpg 1024w, https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-768x512.jpg 768w, https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-1536x1024.jpg 1536w, https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-2048x1365.jpg 2048w, https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2025\/09\/anh-2-18x12.jpg 18w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400\">Hi\u1ec7n t\u01b0\u1ee3ng ng\u00e0y v\u00e0 \u0111\u00eam ch\u00ednh l\u00e0 k\u1ebft qu\u1ea3 t\u1eeb s\u1ef1 v\u1eadn \u0111\u1ed9ng kh\u00f4ng ng\u1eebng c\u1ee7a Tr\u00e1i \u0110\u1ea5t quanh tr\u1ee5c c\u1ee7a m\u00ecnh.
