Tectonic plates move at rates that vary from less than 6 feet per 100 years to 66 feet per 100 years (1.83–20.1 m/100 years); and these rates may have been faster in the ancient past. At an average rate of 33
Indeed, vast lava flows are a common feature of the largest volcanoes on Venus, which are typically located atop topographic rises (e.g., Ivanov and Head 2013). These edifices are classic shield volcanoes, being far broader than they are tall; generally, Venus' largest volcanoes are up to...
"We are interested in large-scale geophysical processes, like how plate tectonics initiates and how plates move underneath one another in subduction zones," said David Goldsby, an associate professor at the University of Pennsylvania. "To do that, we need to understand the mechanical behavior of ...
