Quizplus · Accepted Answer

Plate tectonics and widespread erosion appear to set Earth apart from all the other terrestrial worlds. Plate tectonics is the movement of the lithospheric plates on the surface of the Earth, which leads to the formation of mountains, earthquakes, and volcanoes. Widespread erosion is the process of the movement of rock and soil by wind, water, and ice, which helps to wear down the surface features of the Earth. These two processes are unique to Earth and are not observed on any other terrestrial world in our solar system.
