Izitha zenjoloba ziyizitha ezenziwe ngenjoloba, futhi izinto zenjoloba zodwa zingahlukaniswa zibe irabha yemvelo noma irabha yokwenziwa. Inzuzo yenjoloba yemvelo ukuthi ithambile kakhulu, i-elasticity enhle kakhulu, ingashintshwa ukuze ihambisane nemidlalo ehlukahlukene, ukuze idlale indima ethinta ukushaqeka, kodwa ukungabi nalutho nakho kusobala kakhulu ukuthi ukumelana nowoyela, ukuguga kwe-ozone kanye nokuguga kwe-oxygen eshisayo kumpofu. Izicathulo zezemidlalo zasendlini ngokuvamile zisebenzisa irabha yemvelo.
