erosion-from acidic rain
and sorry cant help you out for a second
Two examples of mechanical weathering are frost wedging, where water freezes in cracks in rocks and expands, causing them to break apart, and root wedging, where plant roots grow into cracks and exert pressure, leading to rock fragmentation.
Erosion and weathering
wind and water
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)
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
Eroision
Two examples of weathering are mechanical weathering, such as when rocks are broken down into smaller pieces by physical forces like wind or water, and chemical weathering, which occurs when rocks are broken down by chemical reactions like oxidation or dissolving.
The 2 kinds of weathering are the Mechanical or Physical Weathering and the Mechanical Weathering.
Physical weathering or mechanical weathering.
Acid rain
Weathering I think
Abrasion and Frost
