Ko te rerekētanga i waenga i te karāpeti me te waro i waenga i ngā matū waro ko te āhua o te hanganga o te waro i roto i ia mea. Ka herea ngā ngota waro ki roto i ngā mekameka me ngā mowhiti. I roto i ia matū waro, ka taea te whakaputa i tētahi hanganga waro ahurei.
Ko te waro te mea tino ngawari (te karāpiti) me te mea tino mārō (te taimana). Ko te rerekētanga matua i waenga i ngā matū waro ko te āhua o te hanganga o te waro i roto i ia mea. Ka herea ngā ngota waro ki roto i ngā mekameka me ngā mowhiti. I roto i ia matū waro, ka taea te whakaputa i tētahi hanganga motuhake o te waro.
Kei tēnei huānga te kaha motuhake ki te hanga hononga me ngā matū ko ia anake, ka taea ai e ia te whakarite me te huri i ōna ngota. O ngā huānga katoa, ko te waro te mea e whakaputa ana i te maha rawa o ngā matū – tata ki te 10 miriona hanganga!
He whānuitia ngā whakamahinga o te waro, hei waro parakore, hei pūhui waro hoki. Ko te nuinga, ka mahi hei hauwaiwai i roto i te ahua o te hau methane me te hinu mata. Ka taea te whakahoro i te hinu mata hei penehīni me te hinu kēhi. Ka whakamahia ēnei matū e rua hei wahie mō te whakamahana, mō ngā mīhini, me te maha atu anō.
Ko te waro anō te kawenga mō te hanga wai, he matū e tika ana mō te ora. Kei te noho hoki hei pūmua pērā i te cellulose (i roto i ngā tipu) me ngā kirihou.
I tētahi atu taha, he allotrope te graphite o te waro; ko te tikanga he matū i hangaia mai i te waro parakore anake. Ko ētahi atu allotropes ko ngā taimana, te waro amorphous, me te waro.
Ko te kupu "graphite" i ahu mai i te kupu Kariki "graphein," ko tōna tikanga i te reo Pākehā ko "te tuhituhi." Ka hangaia ina honoa ngā ngota waro tetahi ki tetahi hei rau, ko te graphite te momo waro tino pumau.
He ngawari te karāpiti engari he tino kaha. He ātete ki te wera, ā, i te wa ano, he pai te kawe wera. Kei roto i ngā toka metamorphic, he rite ki te matū whakarewa engari he mātotoru te tae, mai i te hina pouri ki te mangu. He hinuhinu te karāpiti, he āhuatanga e pai ai te hinu whakahinuhinu.
Ka whakamahia hoki te karāpiti hei tae me te mea hanga i roto i te hanga karāhe. Ka whakamahia hoki e ngā tauhohenga karihi te karāpiti hei kaiwhakahaere irahiko.
Kāore i te miharo te whakaaro he rite tonu te waro me te karāpiti; he whanaunga tata tonu rāua. Nō te waro te karāpiti, ā, ka puta te waro hei karāpiti. Engari mā te tirotiro tata atu ki a rāua ka kite koe ehara rāua i te mea kotahi, engari he rite tonu.
