Maphakathi nobusika, lapho ingxenye enkulu yeYurophu neNyakatho Melika imbozwe yiqhwa, kuyathakazelisa ukwazi kabanzi ngesimo seqhwa ukuze uziqonde kangcono. Ngalesi sizathu sizokutshela 4 ukwazi mayelana neqhwa lokho kuzokumangaza nakanjani.
Ake sazi kabanzi ngaye.
Isithwathwa singaba pinki
Imvamisa, umbala weqhwa umhlophe njengoba ubuso bubonisa ukukhanya kwelanga, kubuyisele esikhaleni, kepha ingahle futhi ibe pinki ngenxa yokuba khona kwe-microalgae engafinyelela izigidi zamakhophi ngesentimitha ngalinye leqhwa njengoba sishilo Lesi sihloko, noma eminye imibala uma ixutshwe nokungcola.
Iqhwa leqhwa aliyona imaminerali
I-amaminerali iqinile ngokufana enokwakheka okucacile (kodwa okungalungisiwe) nokwakheka kwe-athomu oku-odiwe. Iqhwa akusona isimo samanzi esijwayelekile, futhi amanzi awuketshezi awanakho ukuhleleka okuhlelekile, ngakho-ke awuthathwa njengamaminerali.
I-China igubha umkhosi omkhulu weqhwa
Waziwa ngokuthi yiHarbin Ice and Snow Sculpture Festival futhi ubulokhu ubanjwa minyaka yonke kusukela ngoJanuwari 1963.
