How does Venus surface compare with Earths?
On our planet, the crust is really a set of lighter “plates” floating on heavier molten lava. Where the plates buckle or collide, mountain ranges can form; where they rub together, zones of earthquakes and volcanoes occur. We use the term “plate tectonics” to describe these motions of our surface. But Venus does not appear to have plates like Earth. Instead, Magellan has shown us that the geology of Venus seems dominated by hot currents and hot spots beneath the crust, which push and stretch the surface. In the process, blobs of hot lava bubble up to form large land masses, mountains, and the volcanic pancakes and coronae mentioned earlier. Scientists have called the unique geology of Venus “blob tectonics.
