Detailed explanation-1: -These rocks are often called clastic sedimentary rocks. One of the best-known clastic sedimentary rocks is sandstone. Sandstone is formed from layers of sandy sediment that is compacted and lithified. Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves.

Detailed explanation-2: -Sedimentary rocks are deposited in layers as strata, forming a structure called bedding. Sedimentary rocks are often deposited in large structures called sedimentary basins.

Detailed explanation-3: -Sedimentary rocks are layered. Some form when particles of rocks and minerals settle out of water or air.

Detailed explanation-4: -Formation of Sedimentary Rocks Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock.

Detailed explanation-5: -Layered rocks form when particles settle from water or air. Steno’s Law of Original Horizontality states that most sediments, when originally formed, were laid down horizontally. However, many layered rocks are no longer horizontal.
