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.
mechanical weathering
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.
It is classified as physical or mechanical 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.
no because it can use something else than the chemical weathering
A mechanical action would not cause chemical weathering of rock and soil. For example, using a handheld hammer or jackhammer against a stone or rock.
because of the chemical reactions of the abiotic and the digestive system in your body
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.
