Q: Describe Angel Falls.
A: Its water travels hundreds of miles; water falls over 3,200 feet (1,000 meters) down a sheer cliff; much of it is blown away as mist before it reaches the canyon below.

In Erosion and Evolution, geologist Iain Stewart explains that rivers and volcanoes have shaped the Earth in dramatic ways. Rivers sweep rock and debris with them as they head toward the ocean, preparing for new land to form downstream. Scientists have found the conditions that mimic those found when the Earth was young around volcanoes and hydrothermal vents. The changing amounts of ice on the planet also impact how modern man has adapted.
