Umehluko phakathi kolwandle nechibi

Ukubaluleka kwamanzi emvelweni

Amanzi angenye yezinto ezibaluleke kakhulu ekuphileni. Ihlanganisa ngaphezu kuka-70% wobuso beplanethi yethu futhi iyisisekelo sazo zonke izindawo ezisekela ukuphila okuningi. Phakathi kwemithombo yamanzi eyaziwa kakhulu nenkulu kunazo zonke emhlabeni, sithola izilwandle namachibi.

Luyini ulwandle?

Ulwandle indawo enkulu yamanzi anosawoti axhunywe olwandle futhi amboze ingxenye enkulu yeplanethi. Izilwandle ziyizindikimba zamanzi ezinkulu futhi zinwebeka ngamakhilomitha namakhilomitha. Ulwandle lubaluleke kakhulu empilweni yomuntu njengoba, ngaphezu kwendima yalo ezinhlobonhlobo zezinto eziphilayo, luyindlela ebalulekile yokuxhumana nokuthuthwa kwempahla phakathi kwamazwekazi.

Yini ichibi?

Ngakolunye uhlangothi, ichibi liyinqwaba yamanzi ahlanzekile, akhiwe ngenxa yokucindezeleka kwezwe noma isenzo sezinguzunga zeqhwa. Amachibi ayimithombo yamanzi emincane kunezilwandle, futhi ubukhulu bawo bungahluka kakhulu. Zitholakala ezindaweni ezahlukene emhlabeni wethu futhi, ezikhathini eziningi, ziwumthombo wezinsiza ezibalulekile emiphakathini ebazungezile.

Umehluko phakathi kolwandle nechibi

Nakuba womabili amanzi abalulekile emhlabeni wethu nasebukhoneni bethu, kunomehluko ophawulekayo phakathi kwawo okufanele sikucabangele. Ngezansi sibala eminye yale mehluko:

Usawoti

Esinye sezici ezibaluleke kakhulu ezihlukanisa ulwandle nechibi usawoti wamanzi. Ulwandle lunosawoti omningi ngenxa yokuxhumana kwalo nolwandle, kanti amachibi angamanzi ahlanzekile, futhi ngokuvamile awanawo usawoti omningi.

Usayizi

Omunye umehluko obalulekile phakathi kolwandle nechibi ubukhulu. Ulwandle lukhulu kakhulu kunanoma yiliphi ichibi. Izilwandle zimboza izindawo ezinkulu zomhlaba, kanti amachibi ngokuvamile mancane kakhulu futhi atholakala ezindaweni eziqondile.

Impilo yasemanzini

Ngokuqondene nezilwane zasemanzini, kunomehluko ophawulekayo phakathi kolwandle nechibi. Ulwandle luyikhaya lezinhlobo eziningi zezilwane zasemanzini ezingatholakali emachibini, futhi ezijwayela amanzi anosawoti. Ngakolunye uhlangothi, amachibi ayikhaya lezinhlobo zamanzi ahlanzekile, izikhathi eziningi zitholakala endaweni ezitholakala kuyo.

Iziphetho

Sengiphetha, yomibili imizimba yamanzi ibalulekile emhlabeni wethu nasempilweni yazo zonke izinhlobo zezilwane ezihlala kuyo. Ngayinye inezici zayo kanye nezici zayo ezizenza zihluke. Nokho, njengoba sesibonile, kunomehluko obalulekile okufanele siwazi ukuze siqonde kangcono ukubaluleka neqhaza lezilwandle namachibi ohlelweni lwethu lwendalo.
