Chemical, the sodium in the salt exchanges with calcium in the concrete. The chemical products are all water soluble and the surface of the sidewalk washes away.
Water causes mechanical and chemical weathering.
Temperature changes make rocks expand and contract and it is one of the important cause of mechanical weathering. Water abrasion is the other important cause. Wind and moving water cause rocks to rub against each other and the rocks could well break into smaller pieces.
Tornadoes do not cause significant weathering, though they can cause localized soil erosion.
Wind and water are the major causes of weathering and erosion.
Weathering and Erosion.
No, acids cause chemical weathering.
Mechanical.
mechanical weathering
Mechanical weathering includes abrading or crushing. Chemical weathering includes dissolution in water or acid rain. Oxidation and reduction reactions can also cause chemical weathering.
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
Water causes mechanical and chemical weathering.
Factors such as temperature, precipitation, type of rock, vegetation cover, and human activity can influence both chemical weathering (breakdown of rocks through chemical reactions) and mechanical weathering (physical breakdown of rocks into smaller pieces). Temperature can affect the rate of chemical reactions, while precipitation can enhance chemical weathering by providing water for reactions and mechanical weathering by contributing to erosion. Vegetation can impact weathering by producing acids that enhance chemical weathering and by roots that can cause mechanical weathering. Human activity like construction and mining can accelerate both chemical and mechanical weathering processes.
Chemical weathering, such as the reaction of rock with acids or oxidation, does not cause mechanical weathering. Mechanical weathering involves physical processes like freezing and thawing, abrasion, and root growth that break rocks into smaller pieces without altering their composition.
Mountain rocks can undergo both chemical and mechanical weathering. Mechanical weathering breaks rocks into smaller pieces through physical processes like frost wedging and abrasion. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution, which can alter the composition of the rock.
Mechanical weathering. It refers to the breakdown of rocks into smaller pieces without altering their chemical composition. This can occur through processes such as frost wedging, abrasion, and root wedging.

Mechanical weathering is the process of weathering that causes disintegration in rocks but does not change the chemical compound of the rocks. Things like frost, rivers, and tree roots cause mechanical weathering. A large example of this would be the Grand Canyon in Arizona.
