Sedimentary rocks are the most common rock types which are freely exposed on the earth's surface. They are formed from other rock materials since they are made up from the buildup of weathered and eroded preexisting rocks. The weathering, erosion and the eventual compaction of igneous, metamorphic or formerly structured sedimentary rocks among other biological sedimentations leads to the ...

Sedimentary rock, which makes up most of the surface cover of the continents, is by definition deposited by moving fluids. Normally, the sediments contain evidence of their waterborne history in what is called sedimentary structure. These features may be in the form of cross bedding, paleocurrent markers, graded bedding, laminations, ripple marks, etc.
