The weathering of rock by water is in two forms. One is the physical impact of moving water from rain, outflow, or tides. The other is solution, in which water dissolves minerals in the rock surfaces.
Rain and surface water can dissolve gases from the air to form dilute acids that can then chemically react with minerals. This type of erosion can also be seen on stone statues and monuments. The extreme form, which includes dissolved sulfur and nitrogen compounds, is referred to as "acid rain".
Chemical weathering, such as hydrolysis and oxidation, requires water to break down minerals in rocks. Physical weathering processes like freeze-thaw and abrasion can also be enhanced by the presence of water. Water acts as a medium to facilitate the breakdown of rocks and minerals through these processes.

Mass wasting and physical weathering usually require water as the presence of water can increase the likelihood of slope failure and mechanical breakdown of rocks. Chemical weathering can also be facilitated by water as it helps dissolve minerals and facilitate chemical reactions that break down rocks.
Two types of weathering that do not require water are mechanical weathering, such as frost wedging that occurs due to temperature changes, and chemical weathering processes like oxidation, which involves the reaction of minerals with oxygen in the air. These types of weathering can break down rocks and minerals without the direct involvement of water.
That would be oxidation.
Sunlight and wind can cause weathering.

Yes, oxidation is a type of chemical weathering that does require the presence of water to occur. Oxygen in the air combines with minerals in rocks when water is present, leading to the breakdown of those minerals through oxidation.

Chemical weathering typically requires water as a key ingredient. Water can facilitate the breakdown of minerals through processes such as hydrolysis and dissolution, contributing to the overall weathering of rocks and minerals over time.

physical weathering
That would be oxidation.
Mechanical weathering does not require the presence of water. This process involves the physical breakdown of rocks into smaller pieces through factors like temperature changes, frost action, and wind abrasion.
1.Abrasion occurs when two rocks grind together and break up. 2.The repeated heating and cooling of a rock causes heat effects; the expansion and contraction eventually cracks the rock. 3.The physical activity of plants and animals around rocks can contribute to weathering. 4.Oxidation causes weathering by changing a rock's chemical composition. This occurs when oxygen reacts with a mineral; it requires only the presence of oxygen, not water.
