  2. Umbriel (moon)

    Linked via "tectonic resurfacing"

    Craters and Tectonic Inactivity
    The entire surface of Umbriel is saturated with impact features, indicating that the satellite has experienced very little, if any, tectonic resurfacing for perhaps 4 billion years. The craters are generally simple bowl shapes, lacking the terraced walls or central peaks characteristic of larger, geologically active icy bodies like Dione (moon)/) or Titania (moon)/) [8]. The uniformity of cratering suggests that the [interio…
