No, it's not true.
Wetting and drying is considered a part of mechanical weathering. This process occurs when rocks expand when wet and contract when dry, leading to the breakdown of rock material.
Oxidation is a chemical process, not mechanical, that can lead to chemical weathering. It occurs when minerals in rocks react with oxygen in the air or water, causing the minerals to break down and the rock to weaken.
Crushing a sugar cube into a powder is analogous to the process of weathering in the rock cycle. Weathering breaks down rocks into smaller particles through physical or chemical means.
another gas found in air, carbon dioxide, also causes chemical, weathering. Carbon dioxide dissolves in rainwater and in water that sinks through air pockets in the soil. The result is a weak acid called carbonic acid. Carbonic acid easily weathers rocks such as marble and limestone.
Weathering and erosion happen due to the processes of physical, chemical, and biological breakdown of rocks and soil. Weathering breaks down rocks through exposure to elements like water, wind, and temperature changes, while erosion involves the transport of the weathered material by forces like water, wind, and glaciers. These processes shape the Earth's surface over time by wearing down and moving particles from one place to another.
Oxidation plays the most important part in chemical weathering. On copper, brass and bronze it is seen as patina. On iron it is seen as rust. Tin will form a dusty surface oxide layer. Aluminum naturally forms a microscopic oxide barrier on its surface.

Physical weathering involves the breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering involves the alteration of rocks through chemical reactions. Acid rain is a form of chemical weathering, as it can react with rocks and minerals to degrade them.

It depends on what specific part. Or what object is wearing but generally it is called weathering or erosion. Weathering can be either chemical or natural. ;)
Weathering tends to attack the outermost layer of a rock, known as the rock surface or rind, most rapidly. This layer is more exposed to the elements and is therefore more susceptible to weathering processes such as erosion, chemical weathering, and physical weathering.
It's a gerund, although it can be used as a noun.
Weathering attacks the surface of the rock most rapidly.

Selenium is a chemical element; and chemistry is the most important part of science.
Most chemical weathering occurs on the outer surface of a rock because that area is in direct contact with the atmosphere, water, and other substances that promote chemical reactions. As these external agents penetrate the rock, they react with its minerals and cause them to break down, leading to weathering. Additionally, weathering tends to be more pronounced on the outer surface of a rock because it has more exposure to environmental factors compared to the interior.
