Tectonics Tectonics is any stretching or compression of the lithosphere. Usually tectonic activity is due to convection in the mantle below the lithosphere but it can occur when an especially massive landform such as a volcano makes the lithosphere under it buckle from its weight or a rising plume of extra hot material in the mantle pushes on the lithosphere overhead to make a bulge such as coronae features on Venus and possibly the Tharsis Bulge on Mars (though that one may be due to mantle convection long ago). Aine Corona on Venus as seen by Magellan. Aine Corona is approximately 200 kilometers across. Just north of Aine is a 35-km diameter "pancake" dome feature made from extremely viscous (thick) lava. Another pancake dome is inside the western ring of the corona's fractures. Pancake domes are a type of volcanic structure seen only on Venus. Tharsis Bulge side of Mars as seen by the Viking 1 orbiter shows the true "Grand Canyon" of the solar system, Valles Marineris , a huge fracture that probably formed as that side of
