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:
“In the core of God’s abysm,—
Was a weed of self and schism;
And ever the Daemonic Love
Is the ancestor of wars,
And the parent of remorse.”
—Ralph Waldo Emerson (1803–1882)
“‘Tis too plain that with the material power the moral progress has not kept pace. It appears that we have not made a judicious investment. Works and days were offered us, and we took works.”
—Ralph Waldo Emerson (1803–1882)
