Antarctica ili kumwera kwa dziko lapansi, ndipo imagawidwa m'maiko osiyanasiyana. M'madera akutali, makamaka kafukufuku wa sayansi amachitika, koma zikhalidwe pamoyo sizoyenera. Nthaka ya kontinentiyo ndi madzi oundana osalekeza komanso zipululu zachisanu. Dziko lodabwitsa la zinyama ndi zinyama linapangidwa kuno, koma kulowererapo kwa anthu kwadzetsa mavuto azachilengedwe.

Kusungunuka kwa madzi oundana

Kusungunuka kwa madzi oundana kumawerengedwa kuti ndi amodzi mwamavuto akulu kwambiri azachilengedwe ku Antarctica. Izi ndichifukwa cha kutentha kwanyengo. Kutentha kwa mpweya kumtunda kukukulira. M'madera ena nthawi yachilimwe pamakhala kulekana kwathunthu kwa ayezi. Izi zimapangitsa kuti nyama zizolowere kukhala nyengo yatsopano komanso nyengo.

Madzi oundana amasungunuka mosiyanasiyana, ena mwa madzi oundana amavutika pang'ono, enanso amavutika kwambiri. Mwachitsanzo, Larsen Glacier idataya unyinji wake pamene madzi oundana angapo adachoka pamenepo ndikupita kunyanja ya Weddell.

Ozone dzenje ku Antarctica

Pali dzenje la ozoni ku Antarctica. Izi ndizowopsa chifukwa wosanjikiza wa ozoni sateteza pamwamba pama radiation ya dzuwa, kutentha kwa mpweya kumatentha kwambiri ndipo vuto la kutentha kwanyengo limafulumira. Komanso mabowo a ozoni amathandizira kukulitsa khansa, kumabweretsa kufa kwa nyama zam'madzi komanso kufa kwa zomera.

Malinga ndi kafukufuku waposachedwa ndi asayansi, dzenje la ozone ku Antarctica pang'onopang'ono linayamba kulimba, ndipo mwina litha zaka makumi ambiri. Ngati anthu sachitapo kanthu kuti abwezeretse ozoni wosanjikiza, ndikupitiliza kuthandizira kuwonongeka kwa mlengalenga, ndiye kuti dzenje la ozoni pamtunda wa ayezi likhoza kukula

Vuto lakuwononga chilengedwe

Anthu akangofika koyamba kumtunda, adabweretsa zinyalala, ndipo nthawi iliyonse anthu akamasiya zinyalala zambiri pano. Masiku ano, malo ambiri asayansi amagwira ntchito ku Antarctica. Anthu ndi zida zimaperekedwa kwa iwo ndimitundu yamagalimoto, mafuta ndi mafuta omwe amaipitsa chilengedwe. Komanso, zinyalala ndi zinyalala zonse zimapangidwa pano, zomwe ziyenera kutayidwa.

Sikuti mavuto onse azachilengedwe a kontinenti yozizira kwambiri padziko lapansi adatchulidwa. Ngakhale kulibe mizinda, magalimoto, mafakitare ndi anthu ambiri, zochitika za anthropogenic mdera lino lapansi zawononga chilengedwe.
