Uyini umehluko phakathi kwebhola laseMelika nebhola laseYurophu?
Ibhola laseMelika nebhola laseYurophu yizemidlalo emibili ehlukene. Ibhola laseMelika, elaziwa nangokuthi i-gridiron, laqala ukudlalwa ngo-1869 e-United States futhi laziwa kakhulu e-United States naseCanada. Iqhudelana namaqembu amabili enkundleni engunxande. Womabili amaqembu anokuhlasela kanye nokwakheka kokuzivikela. Ukuhlasela kokuqala nokuzivikela komdlalo kunqunywa ngokujikijela uhlamvu lwemali lapho onqobayo enquma ingxenye yokuqala yomdlalo ngenkathi umdlalo ophikisana nawo uqala ngesikhathi sokuphumula. Ithimba elihlaselayo lizama ukuyisa ibhola elinesimo se-oval kolunye uhlangothi lwensimu ngokudlulisa noma ukugijima kulo ekudlaleni ngakunye. Ithimba elivikelayo livimbela ithimba elihlaselayo ukuze lizitholele amabhola ngokwalo noma ngokweba noma lapho ithimba elihlaselayo lingazange lithuthuke ngamamitha ayishumi emidlalweni emine. Khona-ke, iqembu elihlaselayo liba iqembu elivikelayo futhi kube okuphambene nalokho. Lapho iqembu elihlaselayo lifinyelela ngempumelelo emigqeni yamagceke ayishumi, lithola isethi entsha yemidlalo emine ukuze lifinyelele endaweni yokugcina, lapho lithola khona amaphuzu lapho liphumelela, elibizwa ngokuthi i-touchdown.

Abadlali ngokuyinhloko basebenzisa izinyawo zabo ukuze baphokophele ibhola elimise okwengqikithi ensimini liye emgomweni oqondile ogadiwe umgcini wegceke. Umgcini wegoli nguyena kuphela umdlali weqembu ngalinye ongasebenzisa izandla nezingalo zakhe ebholeni esifundeni esithile senkundla esiseduze nemigomo yabo. Umdlalo udlalwa ngokuqhubekayo kuze kube yilapho kwenziwa iphutha noma ibhola liphuma enkundleni. Iqembu ngalinye lizama ukukhahlela ibhola emgomweni ukuze lithole amaphuzu futhi onqobayo yiqembu elinamaphuzu amaningi ekupheleni komdlalo.
