Amaqiniso athakazelisayo ngamalahle Yithuba elihle lokufunda kabanzi ngamaminerali. Namuhla lolu hlobo lukaphethiloli lungenye yezinto ezivame kakhulu emhlabeni. Isetshenziselwa izinjongo zasekhaya nezimboni.
Ngakho-ke, nanka amaqiniso athakazelisa kakhulu ngamalahle.
- Amalahle ezimbiwa phansi izinsalela zezitshalo zasendulo ezilele phansi ngaphansi komhlaba isikhathi eside, ngaphansi kwengcindezi enkulu futhi ngaphandle komoya-mpilo.
- ERussia, ukumbiwa kwamalahle kwaqala ngekhulu le-15.

- Iqiniso elithandekayo ukuthi iChina ingumholi womhlaba wonke ekusetshenzisweni kwamalahle.
- Uma amalahle enziwe ngoketshezi nge-hydrogen, ngenxa yalokho kuzokwenzeka ukuthi kutholakale uphethiloli owuketshezi ofana nezici zawo kawoyela.
- Maphakathi nekhulu leminyaka elidlule, amalahle ahlinzeka cishe uhhafu womkhiqizo wamandla womhlaba.
- Ubuwazi ukuthi amalahle asasetshenziselwa ukudweba namuhla?
- Imayini yamalahle endala kunazo zonke emhlabeni itholakala eNetherlands (bona amaqiniso athakazelisayo ngeNetherlands). Iqale ukusebenza ngo-1113 futhi iyaqhubeka nokusebenza ngempumelelo namuhla.
- Umlilo uvuthe edepho yeLiuhuanggou (China) iminyaka eyi-130, eyacinywa ngokuphelele ngo-2004 kuphela. Unyaka nonyaka, amalangabi abhubhisa amathani angaphezu kwezigidi ezi-2 zamalahle.
- I-Anthracite, enye yezinhlobo zamalahle, inenani eliphakeme kunawo wonke lama-calorific, kodwa ayinakho ukutsha kalula Yakhiwa ngamalahle lapho ingcindezi nokushisa kukhuphuka ekujuleni okungafika kuma-6 km.
- Amalahle aqukethe izinsimbi ezisindayo eziyingozi njenge-cadmium ne-mercury.
