Question

Quizplus · Accepted Answer

Plate tectonics and widespread erosion are the two geological features that appear to set Earth apart from all the other terrestrial worlds. Plate tectonics allows for the movement and recycling of Earth's crust, which in turn drives geological activity, such as volcanism and mountain building. Widespread erosion also plays a significant role in shaping Earth's surface features and altering its landscape. Mantle convection and a thick atmosphere are found on other terrestrial worlds, while a dense core and significant volcanism and tectonics are not unique to Earth.
