Canyons and deep water escarpments...on hand
by Chiara Zuffetti, Earth Sciences Dept. - University of Milan
Sediments travel through impetuous streams which merge into rivers that braid and, finally, flow into the sea. They even go further, along steep escarpments during seismic events. Now let's shrink the scale of observation, reduce the geological times and here we are, looking at this puddle (length of the lower side of the img: 20 cm). The same processes occur at different space-time scales, producing comparable architectures: the multi-scale observation is the most intriguing aspect of the Earth Sciences!
