Final answer:
The novae on Venus are similar to the landforms in Gerya's computer model because they both resulted from volcanic activity, not due to similar surface temperatures, tectonic plate movements, or weather patterns.
Step-by-step explanation:
The novae on Venus are similar to the landforms in Gerya's computer model because a. they both resulted from volcanic activity. The surface of Venus has been shaped by extensive volcanic eruptions, filling the lowland plains with lava, much like the lava formations suggested by Gerya's model. Venus lacks evidence of plate tectonics as observed on Earth, with no subduction zones and crustal spreading. Instead, Venus has its surface renewed by lava flows and similar volcanic features, which are a result of mantle convection causing hot material to emerge on the surface.
Unlike Earth, Venus does not experience the same type of tectonic plate movements that drive continental drift and mountain building. Its geological features, such as coronae and pancake volcanoes, arise from 'blob tectonics,' where the crust is distorted by upwellings of hot material. Therefore, options b, c, and d are not correct comparisons for the novae features on Venus and Gerya's computer model, as they are not supported by the geological processes known to be active on Venus.
