Listed below are geographic features of the terrestrial worlds. in each case, identify the geological process: impact cratering, volcanism, erosion, or tectonics (where tectonics is any large-scale processes affecting the structure of the planetary crust), most responsible for the feature described. match the geographic feature to the appropriate geologic process.
(1.) volcanism: big island of hawaii, smooth surfaces of the lunar maria, mars's olympus mons.
(2.) impact cratering: old surface features of the lunar highlands.
(3.) erosion: earth's grand canyon.
(4.) tectonics: current locations of earth's continents, mars's valles marineris, mercury's many long, tall cliffs.
