No. That is mechanical weathering. Weathering by sand or other matter carried in the wind is a special kind of mechanical weathering called aolean weathering. Weathering by acid rain is an example of chemial weathering. Limestone is particularly subject to this. Illegibility of tombstones in old garveyards provide a good illustration of this.
frost wedging
No. Frost wedging is a type of weathering.
That is something that would show up in bold print in your text book. It's not stupid. physical chemical biological Physical weathering breaks rocks down into smaller pieces. Types of physical weathering include frost wedging, exfoliation, and thermal expansion. Chemical weathering breaks rocks down chemically adding or removing chemical elements, and changes them into other materials. Chemical weathering consists of chemical reactions, most of which involve water. Types of chemical weathering include: dissolution hydrolysis oxidation Biological weathering is the breakdown of rock caused by the action of living organisms, including plants, burrowing animals, and lichen (a crusty, rubbery, light green organic material that grows in patches on rocks as well as on wood). Lichen is a combination of fungus and algae, living together in a symbiotic relationship. Lichens can live on bare rock, and they break down rocks by secreting acids and other chemicals. The fungal part of the association secretes the acids, which react to dissolve the minerals, which are then used by the algae. Later, water seeps into the crevices etched by the acid, and assists in the breakdown through freezing (frost-wedging) and chemical weathering.
hot and dry
Yes, but very little in relation to wetter areas. Most weathering in deserts is due to mechanical weathering processes, such as plant root growth, frost heaving, and most importantly, abrasion from windblown particles.
Frost wedging is classified as mechanical weathering, but does open up rock to further surface attack by chemical weathering.
frost wedging
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
No, it's a purely mechanical action.

Frost wedging, Apex
Therew is only to types of weathering in my knowledge and they are Mechanical and Chemical (in scientific term). Mechanical is also know as physical.
Im not sure but I do know how mechanical weathering breaks down rocks. By frost action or water going inside the rocks and breaking it apart Gravity an example is a rock falling down a hill for and breaking a part into peaces.
Physical weathering
Frost wedging & exfoliation are common terms associated with mechanical weathering.
Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release. Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.
