Ukukhiqizwa kwezikulufu zomhlaba kunikeza izinzuzo zombili zemvelo nezomnotho, kubenza babe ngenye indlela ekhangayo yabathuthukisi nabakhi embonini yezokwakha phakathi kokukhathazeka kwesimo sezulu kanye nokuwohloka kwemvelo. Ngokombono wezemvelo, ukukhiqizwa kwesikulufa emhlabathini kanye nezinqubo zokufaka zikhiqiza imfucuza encane kakhulu ngokuqhathaniswa nezindlela zesisekelo zendabuko. Ukungabikho kokumbiwa noma ukukhishwa kwenhlabathi kunciphisa ingozi yokuguguleka kwenhlabathi nokungcola. Ngokwengeziwe, umnyango wekhabhoni oncishisiwe ohlotshaniswa nokusetshenziswa kwemishini okulula ngesikhathi sokufaka unikela ngokuqhubeka kokuqina. Ngokomnotho, izikulufo zomhlaba kungaholela ekugcinweni kwezindleko okukhulu ngaphezulu kokuphila kwephrojekthi. Inqubo yabo yokufaka esheshayo neqondile yehlisa izindleko zabasebenzi futhi incishise isikhathi sokuphumula. Ngaphezu kwalokho, ukuzivumelanisa nezimo zabo ezimeni zenhlabathi ezahlukahlukene kuvame ukuqeda isidingo sokulungiswa noma ama-worparound angeziwe ngesikhathi sokwakha. Ngaphezu kwalokho, ukuqina okuhlala isikhathi eside kanye nezidingo zokulungiswa okuphansi kwezikulufo ezinomhlabathi zinomthelela ezindlekweni ezingezansi zokusebenza. Izakhiwo ezisekelwa yilezi zisekelo zidinga ukulungiswa okumbalwa kanye nokubuyiselwa kwemali, ukunwebisa isikhathi sazo sonke ngenkathi kunikeza inani elingcono lokutshala imali. Ekuphetheni, izikulufa zomhlaba zibonisa isixazululo sokucabanga sangaphambi kwesikhathi esilinganiselayo umthwalo wemvelo wemvelo ngokusebenza kwezomnotho, ukuveza indlela yezindlela zokwakha ezizinzile kakhulu neziqinile.
