Mixture, Heterogeneous mixture

Explanation:

Mixture can be defined as the combination of two or more pure substance that are not chemically combined and have no definite proportion. Most earth materials are mixture. Example of mixture is air, granite, alcohol and oil. Most mixture can be separated by physical means.

An heterogeneous mixture is the combination of two or more pure substance that are non uniform in composition. Homogeneous mixture, the composition of the pure substances that makes up the mixture are uniformly distributed. Example of homogeneous mixture is air containing oxygen, Nitrogen, carbon dioxide and very little amount of rare gases.

The granite containing various solid oxide of aluminium, sodium, potassium, calcium and iron are combined non uniformly.
