Separating rocks and dirt is a physical change because it doesn't change the identity of either substance.
Crushing rocks is a physical property because it does not change the chemical composition of the rocks. It only alters their physical state or appearance.
yes
No, grinding rocks into gravel is not a chemical change; it is a physical change. In this process, the rocks are broken down into smaller pieces without altering their chemical composition. The material remains the same, just in a different physical form.
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.
Grinding rocks to sand is a physical change, not a chemical change. In this process, the rocks are only being physically broken down into smaller pieces without altering their chemical composition. A chemical change involves a transformation at the molecular level, resulting in the formation of new substances.

Physical
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.
yes
A landslide is only rocks/dirt moving so it is a physical change.
Throwing rocks is a physical change because it does not alter the chemical composition of the rocks. The act of throwing simply changes the position and motion of the rocks, but the rocks themselves remain unchanged chemically.
Of course not. It is a physical change. A chemical change occurs when the identity of a substance changes.
Weathering of rocks can involve both chemical and physical changes. Physical weathering involves the breakdown of rocks without changing their chemical composition, while chemical weathering involves the alteration of a rock's chemical composition through reactions with water, air, or other substances.

it is actually chemistry because i have read in a book[ called go for science and technology which is the science text book for class v five in the school chettinad vidyashram] that rocks are made of chemicals.
No. This is simply a change of state from liquid to solid. It is a physical change.
