Answer Details
Sedimentary rocks are easily recognized in the field because they occur in layers. Sedimentary rocks are formed from the accumulation and lithification (hardening) of sediment, which is often laid down in layers by wind, water, or ice. As each layer of sediment is deposited and buried, it forms a distinct layer in the resulting rock. These layers, also known as strata, can often be seen in exposed rock faces or in cliff formations, making it easy to recognize sedimentary rocks in the field. The layers may also contain visible fossils, which are another characteristic feature of sedimentary rocks. The other options listed do not apply to all sedimentary rocks, as they can occur in a variety of shapes and forms, depending on the geological processes that formed them.
