In soil science, parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical weathering and the mode by which the materials were most recently transported.

Famous quotes containing the words parent and/or material:
“The parent in charge is the disciplinarian.... I do not believe in letting discipline wait for another parent to handle it, nor do I think the father or mother should be allowed to become a shadowy figure who walks in the door and has to play the bad guy in the house.”
—Lawrence Balter (20th century)
“The possibility of interpretation lies in the identity of the observer with the observed. Each material thing has its celestial side; has its translation, through humanity, into the spiritual and necessary sphere, where it plays a part as indestructible as any other.”
—Ralph Waldo Emerson (1803–1882)
