Sedimentary rock is formed by the settling down of bits of sediment material on the surface of the Earth and within bodies of water. The deeper down the layers of sediment are, the older the layer is. If a layer of sedimentary rock is nearer to the surface, then that layer was formed much more recently.
The different layers can show different sorts of records. For example, a fossil found in a deeper layer of sediment is very probably a predecessor of a later fossil found closer to the surface of the Earth. With the help of such dating methods as the layer in which the fossil was found and radiocarbon dating, the numerous finds that have been discovered have revealed a reliable timeline of events related to life on Earth such as evolution, periods of great dyings-out, and periods of new life forms emerging i.e. the Cambrian Explosion.
Sedimentary rocks also reveal a record of geologic activities like great floods and ancient rivers - like the powerful waters that carved out the Grand Canyon.
What else can I help you with?
What do sedimentary rocks preserve?
Sedimentary rocks preserve a record of the environments that existed when they formed.
What two things do sedimentary rocks record?
Sedimentary rocks can record information about the environment in which they formed, such as the presence of water, wind, or ice. They can also preserve evidence of the organisms that lived in that environment, including fossils.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Which is not the process in the formation of sedimentary rocks?
how does the fossil record provide evidence for evolution?!
Which is not a process involved in the formation of sedimentary rocks?
Cementing is not a process involved in the formation of sedimentary rock.
What occurs when sedimentary rocks are deposited on top of uplifted and eroded metamorphic or igneous rocks?
An uncomformity will occur in the rock record.

What are the markings on sedimentary rocks that record the wave motion of wind or water called?
The markings on sedimentary rocks that record the wave motion of wind or water are called ripple marks. They form as sediment is deposited and then ripples are preserved in the rock as it solidifies.
What are the markings on sedimentary rocks that record the wave motion of the wind or water called?
Ripple marks
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Rocks that erodes to expose layering is?
Sedimentary rocks, such as sandstone or shale, erode to expose layering due to the distinct horizontal beds created during the deposition process. The layering, or bedding, in sedimentary rocks forms as sediments settle and accumulate over time, preserving a record of the Earth's past environments and processes.
