| landscape | general chape of a region on Earth's surface |
| moraine | unsorted mound of sediment depositied directly by moving ice |
| mountain | landscape region characterized be non-horizontal rock structure & great topographical relief; landscape feature usually characterized by nugh elevation & steep slopes |
