Calcrete is a type of limestone that forms in semi-arid to arid climates through the precipitation of calcium carbonate from groundwater. It typically occurs as cemented layers or nodules within soils or in desert pavements. Calcrete is commonly found in regions like Australia, Africa, and the southwestern United States.
The chemical composition remain unchanged.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.

Yes, the composition of the rocks is as a result of the distinct chemical composition.
The chemical composition of water remain unchanged.
A chemical change involve a change of composition.
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
Several chemical properties can be estimated knowing the chemical composition.
The color of a mineral sample is determined by its chemical composition
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
