Earth's tectonic activity is a significant factor that made life on Earth possible because the movement of Earth's crustal plates affects?
is affected by volcanic activity and the atmosphere.
The transfer of heat from the interior of the planet to the surface which is the cause of tectonic plate movement creates surface features such as rifts, mountains, volcanic mountains, island chains, basins, folded rock, faults, and trenches. Geologic activity resulting from plate tectonics includes volcanism, landslides, avalanches, desertification, and tsunami and earthquake activity.
It is smooth, but is not as smooth as originally thought. There is evidence that there is tectonic activity and that it has similar geological features. Venus is thought to be behind schedule with the tectonic activity which is how they explain the difference in surface. It is just starting out it's tectonic activity.
