Hint: Sedimentary rocks are the rocks which cover majorly 75% of the continents. These rocks are sediments that have been packed and cemented tightly to form a solid rock body.
Complete answer:
> Sedimentary rocks are types of rock that are formed by the collection or deposition of the minerals or the organic particles present at the Earth's surface. followed by the cementation.
> Sedimentation,this is the name for processes that cause these particles to settle collectively in a particular place. These rocks tell us about the past environments on the Earth's surface.
> Due to this reason they are the primary story-tellers of early life,and past climate and the major events occurring at the Earth's surface. Different environments have particular processes which occuring. That causes a particular type of sediment to be deposited over there.
> The study of the sedimentary rock strata with proper sequence is the main source to understand the Earth's history. It includes palaeo-geography, paleo-climatology and the history of life.
> Scientific discipline , studied the properties and the origin of sedimentary rocks and us called sedimentology. It is part of both geology and geography.
> The accumulation of dirt over large bodies of water, also can trap and fossilize plants as well as animal remains. The strata of the rock is equated with the timeline of its formation. Thus, a "history" of the earth at that place shows by sedimentary rock.
Note:The sedimentary rock covers continents of the Earth's crust.this rock contains only 8% of the volume of earth's crust. These rocks are thin.the crust mainly consist of igneous rocks and the metamorphic rocks.
