When discussing the "biggest" waterfall in the world, one must first clarify the criteria. Waterfalls are measured by two primary metrics: height (the vertical drop) and volume/width (the sheer amount of water flowing over the edge). Depending on your definition of "biggest," the answer points to two very different geographical locations: Venezuela and Zambia/Zimbabwe.

The Tallest Waterfall: Angel Falls, Venezuela

If your definition of "biggest" refers to the sheer vertical drop, the undisputed champion is Angel Falls (Salto Ángel) in Venezuela. Located within the Canaima National Park, a UNESCO World Heritage site, this waterfall plunges from the summit of the Auyán-tepui, a massive flat-topped mountain (tepui).

• Height: The total height is 979 meters (3,212 feet), with a single uninterrupted drop of 807 meters (2,648 feet).
• Discovery and Context: While indigenous Pemon people have known of the falls for centuries, it was popularized by American aviator Jimmie Angel, who crash-landed his plane atop the tepui in 1937. His story is detailed extensively in The Lost World of the Guiana Highlands by author Adrian Warren.

Angel Falls is so high that much of the water evaporates or turns into a fine mist before it even reaches the base, especially during the dry season. It is a testament to the dramatic geological formations of the Guiana Shield, which are among the oldest rock formations on Earth.

The Largest by Volume and Width: Victoria Falls

If "biggest" implies the most powerful, widest, or most voluminous sheet of falling water, the title belongs to Victoria Falls, located on the border between Zambia and Zimbabwe. Known locally as Mosi-oa-Tunya ("The Smoke That Thunders"), this waterfall is widely considered the largest curtain of falling water in the world.

• Dimensions: It spans a width of 1,708 meters (5,604 feet) and reaches a height of 108 meters (354 feet).
• Hydrology: During the peak flood season, over 500 million liters of water plummet over the edge every minute. The spray from this cascade can be seen from over 40 kilometers away.
• Historical Documentation: The falls were famously "discovered" by the Scottish explorer David Livingstone in 1855, who named them after Queen Victoria. Livingstone’s accounts, found in his seminal work Missionary Travels and Researches in South Africa, describe the awe-inspiring sight of the Zambezi River plunging into a deep, narrow chasm.

Unlike Angel Falls, which is a thin, wispy descent, Victoria Falls is a massive geological rupture. The basalt rock formations surrounding the falls have been carved by the Zambezi River over millions of years, creating a series of zigzagging gorges that showcase the incredible erosive power of water.

The Complexity of "Big"

It is essential to note that scientists and geographers often argue over what constitutes "big." If we consider the Iguazu Falls on the border of Argentina and Brazil, we find a system of 275 individual drops spanning nearly 2.7 kilometers. While no single drop matches the height of Angel Falls or the singular curtain of Victoria Falls, the total volume and complexity of the Iguazu system are unrivaled.

Furthermore, there is an underwater "waterfall" in the Denmark Strait. This is a submarine cataract caused by the temperature difference between the cold water of the Greenland Sea and the warmer water of the Irminger Sea. The water drops over 3,500 meters (11,500 feet), far dwarfing any terrestrial waterfall. This phenomenon is documented in the oceanographic studies of the Woods Hole Oceanographic Institution.

Conclusion

In summary, the answer to which country has the "biggest" waterfall depends on your criteria:

1. For vertical height: Venezuela claims the title with Angel Falls. It is a masterpiece of geological verticality, located in the remote wilderness of the Gran Sabana.
2. For width and volume: The border of Zambia and Zimbabwe claims the title with Victoria Falls. It represents the sheer, thundering power of a major continental river system.

If you are looking for the most impressive visual experience, Victoria Falls is generally considered the most "massive" in terms of scale and accessibility. However, for those seeking the extreme limits of nature's vertical reach, the jungles of Venezuela remain the ultimate destination. Understanding these distinctions allows for a deeper appreciation of how water shapes our planet, whether through the slow, steady erosion of a gorge or the sudden, gravity-defying drop from a mountain peak.
