Not exactly. A physical change is when a substance is changed, but can be reverted back to its original form. An example of this is water. If you heat up water it turn to water vapor (steam) and when it cools down, it turns back into water again. When you freeze water it turns to ice, but if you heat it up, it turns back to water. I think you're talking about chemical change. A chemical change is changing a substance to a new one and cannot be reverted back into its original form. An example of this is a burning paper.
Soil is considered a mixture because it is made up of various components like minerals, organic matter, water, and air. It is a complex combination of both organic and inorganic materials that interact to support plant growth and other ecosystem functions.
