Sedimentary rocks are made up of pieces of older rocks (igneous, metamorphic, and sedimentary) and organic remains (shells, bone, etc.). When rocks break apart from erosion they are transported by ...

Alternatively, sedimentary rocks take shape when the tiny, weathered fragments of stones are compacted and cemented together. The process begins when rocks, minerals and organic materials — such as ...

Plastistones, a new type of sedimentary rock that’s part-plastic and part-rock, has been found on at least five continents and 11 countries. These rocks form when molten plastic cools within a ...

AS the rocks which form the continental masses are disintegrated by the action of weathering and other geological agents, their detritus accumulates to form sedimentary rocks, ultimately on the ...
