  • Both the moon and Earth are tectonically active; however, the tectonic forces affecting each body are different. Earth’s crust is divided into plates that have converged, separated, and slide past each other to produce expansive mountain ridges, deep ocean trenches, and a ring of volcanoes around the Pacific Ocean. The moon’s crust is not divided into plates, yet stresses within the lunar crust give rise to several distinctive landforms.

    One of the most common of these is lobate scarps, which form when the crust compresses and the resulting forces push material up and over adjacent crust along a fault, creating a ridge. These scarps, found in the lunar highlands, have formed only within the last billion years, or the last 20% of the moon’s history.
