Which statement concerning sedimentary rocks is not true? They were originally deposited at depth below the bottom of the sea. They are composed of particles and constituents derived from weathering and erosion of other rocks. They probably show some evidence of stratification. They may contain fossils that provide clues about ancient life forms.

The formation of the sedimentary rocks takes place when the deposition of sediment takes place out of gravity, ice, air, wind, or with the flow of water flows that carries the suspended particles.

The sedimentary rock often results from weathering and erosion, when a rock breaks down a rock into loose and small particles in the area.

The formation of the sedimentary rock takes place in 4 major ways:

When sediments are consolidated and accumulated.
The resultant of the deposit from the biogenic processes
When the rocks are weathered, their remains leads to the formation of clastic sedimentary rocks.
From the precipitate of a solution.

Thus sedimentary rocks were not deposited at a depth below the sea bottom originally.
