Rock Units. A lithostratigraphic unit is defined as a body of sedimentary, extrusive igneous, metasedimentary, or metavolcanic strata which is distinguished on the basis of lithologic characteristics and stratigraphic position (position in the rock sequence).The smallest lithostratigraphic rock unit is the bed.edimentary environments that started out side-by-side will end up overlapping one another over time due to sea level change (transgressions and regressions). The result is a vertical sequence of beds. The vertical sequence of facies mirrors the original lateral distribution of sedimentary environments.
The US Supreme Court, as an institution, is head of the Judicial Branch. The Chief Justice of the United States presides over the Court and is the head of the judiciary during his (or her) tenure, but the Associate Justices don't really play a leadership role.

The Constitution is the highest law of our Nation. The U.S. Supreme Court, the highest court in the United States, is part of the judicial branch. The Supreme Court is made up of 9 judges called justices who are nominated by the President and confirmed by the Senate. The justices hear cases that have made their way up through the court system.
