Chemical Sedimentary Rocks such as Halite provide us with natural salt from the evaporated water.... if u ever wanted to know were our salt in saltshakers come from ;)
The two main features of sedimentary rocks are: They are formed into strata or layers. They consist of many palaentological evidences like fossils and coal.
Answer: Sedimentary rocks contain the entire history of life on earth that is available to us, and much of the history of the Earth itself. All of this information will help us determine how we got where we are today.
A very old fossil in sedimentary rocks is called a "trace fossil" or "index fossil." These fossils provide valuable information about past life forms and help scientists understand Earth's history.
Kaibab Limestone is not an organic sedimentary rock, but classified only as a sedimentary rock. Organic sedimentary rocks form from the remains of carbon rich plant life normally.
Sedimentary rocks are the result of weathering, and erosion of other rocks within the rock cycle and from the death and deposition of organic material. As the earth did not have an atmosphere as it first began to form, it had no rivers, no weather and no life. Therefore all of the processes required to produce sedimentary rock were absent.

Fossils.

NO
Igneous rocks are typically older than sedimentary rocks. Igneous rocks form from the cooling and solidification of molten material (magma or lava), which usually happens before the formation of sedimentary rocks through processes like erosion, deposition, and compaction.
Organic sedimentary rocks are formed from the remains of plant and animal life. Chemical sedimentary rocks are formed from the precipitation of minerals in a solution.

The rocks of Earth's crust, especially sedimentary rocks
Sedimentary rocks show fossils, because of pre-existing life forms. They also show ripple marks due to weathering and erosion...
i dont knoe
They improve communications.
