- Ice wedging into the rock and breaking and cracking the rocks and soil: Weathering. Ice expands in cracks, physically breaking apart rock and soil without transporting material.
- The wind blows sand to form a sand dune: Deposition. Wind transports sand particles and drops them to build up a dune.
- Unique rock shapes that form when wind and/or water cause various particles to hit the rocks which creates unique rock shapes over time: Erosion. Wind or water carries abrasive particles that wear away rock surfaces, changing their shape.
- A sinkhole forms when the rock below the ground wears out and then everything about it gives way and caves in: Weathering. Chemical or physical breakdown of subsurface rock (often limestone) leads to collapse; the material is not transported away but dissolves or crumbles in place.
- Waves dropping sand on the beach: Deposition. Waves carry sediment and leave it behind as they lose energy on shore.
- A lot of rain quickly or the rapid melting of snow will cause a landslide: Erosion. Water saturates soil and rock, causing mass movement downhill; material is transported from its original location.
