Victoria Falls is unlike any other landform examined before. They waterfalls are wider and deeper than Niagra Falls, making the waterfall one of the largest in the world. The bottom or bed of the falls contains hard and thick rock. The rock formed from basalt lava flows millions of years ago. The lava flows came from very strong volcano activity that no longer occurs today.

The fissures that lie within the basalt of Victoria Falls were caused by tectonic plates shifting millions of years ago, as well. Once the fissures existed, the Zambezi River flowed over the fissures and created large waterfalls. The river flowed rapidly with the influence of the fissures. The mass flowing of the Zambezi River also caused the gorges that contribute to the waterfalls to expand through erosion. Therefore through erosion, the gorges have a zigzag shape or pattern.

Deposits settle into the fissures, and sedimentary rock formed, as it lies there still today.

The Zambian people who live around Victoria Falls have succeeded in that Victoria Falls attracts tourism. Though Zambian, Zimbabwean, and/or the people of Victoria Falls do not depend on the falls for any life source, it is a huge attraction and beauty.
