Maphakathi nobusika, lapho ingxenye enkulu yeYurophu neNyakatho Melika imbozwe yiqhwa, kuyajabulisa ukufunda kabanzi mayelana nokwenzeka kokuwa kweqhwa ukuze ukuqonde kangcono. Ngenxa yalesi sizathu, sizokutshela 4 ilukuluku mayelana neqhwa lokho kuzokumangaza impela. Ake sifunde okwengeziwe ngaye.
Isithwathwa singaba pinki
Ngokuvamile, umbala weqhwa umhlophe, njengoba ingaphezulu libonisa ukukhanya kwelanga, likubuyisele emkhathini. Nokho, ingahle futhi ibe pinki ngenxa yokuba khona kwe-microalgae iqanjwe I-Chlamydomonas nivalis, engafinyelela izigidi zezibonelo ngesentimitha leqhwa. Lokhu kungabonwa ezindaweni eziningana ezinezintaba. Ukuze ufunde kabanzi mayelana naleli lukuluku, vakashela isihloko esithi liyini iqhwa elipinki. Isithwathwa singaphinde sibe neminye imibala uma sihlangana nokungcoliswa kwemvelo, okulenza libe yinto ebonakalayo ebonakalayo. Uma ufuna ukujula esihlokweni, ungafunda ngaso Liyini iqhwa lekhabe?. Ngaphezu kwalokho, lezi curiosities kube isihloko ocwaningweni ezahlukene mayelana sezulu kanye ilukuluku elihlobene nobusika.
Ikhekheba leqhwa aliyona amaminerali
Ngokombono wesayensi, i-mineral iyi-homogeneous solid enokwakheka kwamakhemikhali okuchaziwe kanye nokuhlelwa kwe-athomu okuhlelekile. Kunalokho, Iqhwa alisona isimo samanzi esivamile, futhi amanzi awuketshezi akanalo isakhiwo esi-odiwe, ngakho amakhekheba eqhwa awabhekwa njengamaminerali. Ngaphezu kwalokho, ikhekheba leqhwa ngalinye lihlukile, linomumo ohluka ngokuya ngezimo zezulu nezemvelo elakheka ngaphansi kwazo. Ukuze uthole ulwazi olwengeziwe mayelana nalesi simo, ungathintana yini iqhwa, lapho uzofunda okwengeziwe ngomhlaba othakazelisayo wamakhekheba eqhwa nezinye izici ze ilukuluku mayelana namakhekheba eqhwa. Izakhiwo zamakhekheba eqhwa ziyisihloko sokuthakazelisa nokufunda emkhakheni we-meteorology.
I-China igubha umkhosi omkhulu weqhwa
IHarbin, eShayina, isingatha uMkhosi Wokudweba Iqhwa Neqhwa, umcimbi obulokhu wenzeka minyaka yonke kusukela ngo-January 1963. Phakathi nalo mkhosi, izakhamuzi nezivakashi ngokufanayo zijabulela izithombe eziqoshiwe ezenziwe ngeqhwa neqhwa, ezilondolozwe ngenxa yamazinga okushisa aphansi akulesi sifunda, ahamba cishe -18.3°C phakathi nenyanga yokuqala yonyaka. Lo mcimbi uheha izivakashi ezisuka kuwo wonke umhlaba, okwenza i-Harbin ibe yindawo edumile yasebusika. Uma ungathanda ukuthola okwengeziwe, ungafunda okwengeziwe kulesi sihloko, oqinisekile ukuthi uyasithanda, njengoba sihlanganisa amaqiniso athakazelisayo mayelana namaholide ahlukahlukene asebusika.
Likhithika kwamanye amaplanethi
Kungase kusimangaze ukucabanga ukuthi likhithika kuphela lapha, eplanethini enguMhlaba, kodwa akunjalo. Isithwathwa naso siwela eMars naseVenus, nakuba kungenjalo ngendlela esiyibona ngayo emhlabeni wethu. Ku-Mars, iqhwa lakhiwa isikhutha futhi liwa njengenkungu ngezikhathi ezithile zonyaka. Ngakolunye uhlangothi, kuVenus, iqhwa lenziwe nge-pyrite, imineral ehwamuka ngenxa yamazinga okushisa aphezulu emkhathini. Lezi zici zibonisa ukuthi iqhwa, nakuba lijwayele kithi, lingakwazi ukuzibonakalisa ngezindlela ezihluke ngokuphelele kwamanye amazwe. Uma unentshisekelo, ungathola okwengeziwe mayelana Ilukuluku mayelana nePluto namanye amaplanethi futhi ufunde ngezinye izigigaba ezithakazelisayo ezihlobene nesimo sezulu.
Okuningi okuthakazelisayo mayelana neqhwa
- Iqhwa alimhlophe ngempela. Njengoba sishilo ekuqaleni, iqhwa alinambala, kodwa ukubukeka kwalo okumhlophe kubangelwa indlela ukukhanya okubonisa ngayo amakristalu alo.
- Ngokumangalisayo, u-75-80% wamanzi ahlanzekile oMhlaba atholakala ngesimo seqhwa noma iqhwa, kuhlanganise nezinguzunga zeqhwa.
- Iqhwa lingawa ngezindlela ezahlukene, kuhlanganise imvula (ingxube yeqhwa nemvula) kanye i-cilantro (iqhwa eligayiwe).
- I-Sapporo, eJapane, yaziwa njengedolobha elineqhwa kunawo wonke emhlabeni, elinesilinganiso sonyaka seqhwa elingu-595 cm.
Umthelela weqhwa endaweni ezungezile
Iqhwa lidlala indima ebalulekile ekulinganiseni kwesimo sezulu soMhlaba. Ukuba khona kwayo kunemiphumela eminingi, njenge umphumela we-albedo, lapho iqhwa libonisa u-80-90% wokukhanya kwelanga, lisiza ukulawula izinga lokushisa lomhlabathi. Lokhu kubalulekile ekugcineni isimo sezulu esizinzile ezindaweni ezibandayo futhi kunomthelela wokufudumala kwembulunga yonke. Ungafunda kabanzi mayelana ne- ukufudumala kwembulunga yonke kanye nomthelela wako ezicini zeqhwa kanye nesimo sezulu.
Kubalulekile ukuqaphela ukuthi ukuncibilika kweqhwa kuwumthombo obalulekile, ohlinzeka ngamanzi abalulekile emifuleni nasemachibini, abalulekile ohlelweni lwemvelo, ezolimo, kanye nokusetshenziswa kwabantu. Ngaphezu kwalokho, izigaxa zeqhwa zinamandla okushisa aphezulu. Leli qiniso livumela izilwane, isibonelo, ukusebenzisa iqhwa ukuze zakhe izindawo zokukhosela ebusika. Izici zokuvikela iqhwa zivumela izilwane ezinjengamabhere asezindaweni ezishisayo nonogwaja be-snowshoe ukuba bazivikele emakhazeni ashubisa umnkantsha abonisa indawo ezikuyo. Ungabona okwengeziwe ngalezi zilwane ku amazwe abanda kakhulu emhlabeni, lapho kuphinde kuxoxwe ngomthelela wamakhaza ezilwaneni zasendle.
Naphezu kobuhle balo, iqhwa lingaba yingozi. Enye yezingozi ezihlobene neqhwa ikhono lalo lokuveza imisebe ye-ultraviolet, engaholela esimweni esaziwa ngokuthi i-photokeratitis, okubangela ukuvuvukala okubuhlungu kwe-cornea futhi kungaholela ekulahlekelweni kombono okwesikhashana. Ngakho-ke, kunconywa ukuthi labo abachitha isikhathi bengaphandle ezimweni zeqhwa bagqoke ama-eyewear okuzivikela.
Ngaphezu kwalokho, iqhwa lingaba yimbangela yama-avalanche, ikakhulukazi ezindaweni ezinezintaba. Ukunqwabelana kwesithwathwa kungase kungazinzi, okuholela kumaslayidi ayingozi angafaka ukuphila kwabashushuluzi nabaqwali izintaba engozini. Imfundo emayelana nezimo zeqhwa kanye nokusetshenziswa kwemishini efanele ibalulekile ukuze ujabulele imisebenzi yeqhwa ngokuphepha. Ungathola futhi ngezinye izinto nezici ezizungezile.
Amanye amaqiniso athakazelisayo mayelana neqhwa
Kunamaqiniso amaningi athakazelisayo mayelana neqhwa abantu abaningi ababengawazi:
- Ikhekheba leqhwa elikhulu kunawo wonke ake aqoshwa anobubanzi be 38.1 cm futhi yabhaliswa eFort Keogh, eMontana, ngo-1887.
- Iqhwa libhalwe ezindaweni ezingavamile kakhulu, njenge-Sahara Desert, lapho iqhwa laqoshwa khona ngo-2016. Lokhu kubonisa ukuthi iqhwa lingaba khona izindawo ezingalindelekile njengeSahara.
- Usuku Lomhlaba Lweqhwa lugujwa njalo ngeSonto lesithathu ngoMasingana emhlabeni wonke, lukhuthazwa yi-International Ski Federation.
- Ubusika ngabunye, kulinganiselwa ukuthi cishe a amakhekheba eqhwa angama-quadrillion kuyo yonke iNyakatho nenkabazwe.
Ukuqonda iqhwa kudlula ukujabulela indawo yasebusika; Kubalulekile ukuqonda ukwakheka kwayo, umthelela wayo kwezemvelo, kanye nezinyathelo zokuphepha ezidingekayo ukuze uxhumane nalesi simo semvelo ngokuphepha nangokuzibophezela. Ngokufunda ngeqhwa, sicebisa ukuxhumana kwethu nendawo ezungezile futhi sibona ukubaluleka kwalo hhayi kuphela esimweni sezulu kodwa nasezintweni zethu zansuku zonke, kusukela kwezemidlalo kuye kwezolimo.
