One is the elephant rocks that you see in the American southwest. These interesting formations are a result of weathering by wind that picks up very small clasts from sand dunes
two examples of mechanical weathering are called wind ,and water.
wind and water
Soil particles carried by the wind.

Wind weathering is the process were small sediments and/or sand is brushed against rocks due to abrasion.
Wind and water are agents of erosion

Erosion and weathering
well it is very hard to break up bedrock, but the main process that does is weathering. You have two seperit kinds of weathering. The first one is Chemical Weathering. Chemical weathering is when weathering effects the exterior. two examples are rust and leaching. The second type of weathering is Mechanical Weathering. This effects rocks physically. two examples are abrasion and erosion.SO THE MAIN ANSWER WOULD BE WEATHERING. THE TYPE OF WEATHERING, MECHANICAL WEATHERING, THE PROCESS, ABRASION (well there is more than that but that is the most common situation)
