Wonder Dog digging in the soil[1]

Soil is a natural body consisting of layers (soil horizons) that are primarily composed of minerals which differ from their parent materials in their texture, structure, consistency, color, chemical, biological and other characteristics. It is the unconsolidated or loose covering of fine rock particles that covers the surface of the earth. Soil is the end product of the influence of the climate (temperature, precipitation), relief (slope), organisms (flora and fauna), parent materials (original minerals), and time. In engineering terms, soil is referred to as regolith, or loose rock material that lies above the 'solid geology'. In horticulture, the terms 'soil' is defined as the layer that contains organic material that influences and has been influenced by plant roots and may range in depth from centimetres to many metres.

During the Cosmic Crisis, Wonder Dog ended up in the back of a dump truck which was hauling soil, it dumped him and the soil out, and because of that, he lost a piece of paper that he was supposed to take to the Justice League, because it contained a message for them.[2]

The Mole family's drillmobile was capable of boring through solid rock and soil.[3]
