What are characteristics of sedimentary rocks?
GeologySedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth’s surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers. What are
