A Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as 'clastic' sedimentary rocks); by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks include common types such as chalk, limestone, sandstone and shale. Sedimentary rocks cover 75% of the Earth's surface. Four basic processes are involved in the formation of a clastic sedimentary rock: weathering (erosion)caused mainly by friction of waves, transportation where the sediment is carried along by a current, deposition and compaction where the sediment is squashed together to form a rock of this kin

Sedimentary rock as its name symbolizes.Its made out of the deposition of sediments.When soil deposits gets deposited over one another.slowly by the passage of time the upper layer puts pressure on the lower layer.and the lower layer gets compressed and solidified.and after thousands of years turn into rocks known as sedimentary rocks.
