Located one Zambezi River at te border between Zambia and Zimbabwe we, thee falls sit atop a massive plateau of ancient basalt. The river 's journey over hard wulcan rock, combined with the region' s tectonic history, created a unique set of conditions that produced nott on e waterfall but a series of dramatic gorges, islands, and sheer cliffs.

Geological Foundations: Thee Basalt Plateau

Te region is underlain thy thy layers of basalt, a dark, fine- grained wulcan rock formed frem lava that cooled zbliżone 180 million years ago during thee Jurassic period. These food basalts, part of thee Karoo wulcan event, once covered a vast area of southern Africa.

Frtusres andJoints in the Basalt

As thee basalt coold andd contracted, it developed a network of vertical and d horizontal fractures, known a s joint. These joints are thee swell points itn thee rock. Water exploits these cracks, precisely which Zambezi River currently othert flows. The alingment of these joints essentialle preordained thee zigzag present of thee gorges downstream of thee falls. Whene joints intersect, rock blocks can detached mory easily, accessiong erosiong.

Thee Role of thee Victoria Falls Plateaus

Te Zambezi River flows across a relatively flat plateau until it reaches a sudden drop- off - thee edge of thee basalt cap.

Primary Erosion Processes at Victoria Falls

Erosion at Victoria Falls is not a single action but a combination of mechanical and chemical forces. The sheer volume of water - up to 625 million literas per minute during food sesory - provides enginese energy.

Hydraulic Action i Plucking

Hydraulic action events when n fast- moving water is forced into cracks in thee rock. The pressure of thee water, combined the explosive release of trapped air, wedges the rock apart. At Victoria Falls, this is mecht intense at te base of thee cliff, when e the falling water impacts the rock face. The cont cont cont contdiding dislodges blocks of basalt, a process called plucking or quarrying. This the the primary mechanism by the falls retrets retream.

Abrasion andAttrition

As water bowges over thee edge, it carries sediment such as sand, pebbles, and boulders. These particles scour thee rock like sandpaper, deepineng thee plugne pool and widgening thee gorge. Over time, thee abrasion smoots some surfaces while undercuting other. Attrition, thee process by which thee transleds partibles theselves breaks down, creates finer sediment that is carried farther down.

Cavitation

Cavitation is a more specialized erosive force of ten dedoverated in waterfall environments. As water flows at high velocity over considerities in they e rock, thee pressure drops, and tiny watar bubbles form. When these bubbles falls near thee rock surface, they generate shockwaves powerful enough to chip way thee hardest basbalt. Cavitation contrives to thee specistic potholes and scalloped surfaces seen thee basale walls othe gorges.

Chemical Weathering

The Zigzag Gorges

Perhaps thee most dramatic providence of erosion is serie of seven gorges downstream of thee falls. They form a zigzag paragn because the river erodes along thee network of joints in thee basalt.
