What is another word for bedrocks?
Pronunciation: [bˈɛdɹɒks] (IPA) 
Bedrocks are the fundamental or underlying principles upon which something is built or established. Synonyms for bedrocks include foundation, cornerstone, base, footing, groundwork, and infrastructure. These words all refer to the essential starting point upon which progress or development can be made. Just as a building needs a strong foundation to stand, any idea, organization, or relationship requires a solid bedrock on which to build. A bedrock can also be thought of as a guiding principle or core value, upon to which all decisions and actions are based. Without a bedrock, any endeavor is likely to falter or fail.
