It is a physical phenomenon.
no its a physical change

Weathering is the term used to describe the reduction in the size of a rock by chemical or physical means.
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.
It is a physical change. There are no changes made to the compounds in a pencil by breaking it.
When a rock is exposed at the Earth's surface, it will undergo weathering, where it breaks down or decays due to various processes like physical, chemical, or biological factors. Over time, weathering can cause the rock to fragment into smaller pieces and eventually contribute to the formation of soil.
Weathering can involve both physical and chemical changes. Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, such as through freezing and thawing. Chemical weathering, on the other hand, alters the chemical makeup of rocks through processes like oxidation or dissolution.
Household cleaners undergo chemical changes when the active ingredients in the cleaners interact with substances they are designed to clean. For example, when a cleaning agent breaks down grease or dirt on a surface, it is undergoing a chemical change. This can result in the formation of new compounds that help effectively clean the surface.
Stretching a piece of plastic until it breaks is a physical change because the bonds between the plastic molecules are being rearranged and broken without changing the chemical composition of the plastic itself.
When glass breaks, it is considered a physical change rather than a chemical change. This is because the composition of the glass remains the same; only its shape and structure change. In a physical change, the material's properties may alter, but no new substances are formed, which is the case with broken glass.
it would be a chemical reaction mArKe ^_^
Digestion is a chemical process that breaks down food particles into smaller molecules through the action of enzymes. It involves the breakdown of complex molecules into simpler ones through chemical reactions.
