Question

multiple choice question to classify sediments as lithogenous means that they are derived from ______. options: preexisting rocks, space, marine organisms, seawater

Explanation:

Lithogenous sediments are defined as sediments derived from preexisting rocks (through processes like weathering and erosion). Sediments from space are cosmogenous, from marine organisms are biogenous, and from seawater (chemical precipitation) are hydrogenous. So the correct source for lithogenous sediments is preexisting rocks.

A. preexisting rocks
