Sediments etch the footprints of moving animals when they become rocks. Sedimentary rocks are created by the material being deposited at the Earth’s surface and then being cemented there by bodies of water. There are four ways that these rocks are formed.
- accumulating worn fragments of other rocks
- Sediment accumulation and consolidation
- Deposition of biogenic activity’s results
- Rain from the solution.

What is sedimentation?
All of the processes that lead to the sedimentation of organic and mineral particles are together referred to as sedimentation. Sediment is the term for the component that aids in the formation of sedimentary rock. This sediment is created by weathering and erosion at the source area, and it is subsequently carried to the deposition site by denudation-causing elements like wind, water, ice, and glaciers.
The sediment particle size and fluctuation is the best indicator of the type of rock. The characteristics and patterns of the grain in such sediments are referred to as its texture. Its structure can be found beneath surfaces and in rock beds where it has deposited and helped record the paleocurrent. The crust of the planet is covered by these rocks, yet their combined contribution to the crust’s overall volume is only thought to be 8%.
Summary:
Sediments ____ the footprints of moving animals when they become rocks.(a) preserve(b) keep(c) take(d) etch
Sediments etch the footprints of moving animals when they become rocks. The three types of sedimentary rocks are categorised as Organic, Clastic, and Chemical Sedimentary Rocks.
