How is Soil Formed?

Soil formation occurs on different parent materials such as bedrock or recent cover deposits. As rocks become exposed at Earth’s surface they are physically and chemically changed through weathering processes.

The nature of the parent material strongly influences soil properties; hence, if you want to know how to manage your soil sustainably you need to learn about its parent material. Use the map below to discover major types of soil parent materials.
