Sedimentary rocks are one of the three main rock groups (the other two being igneous and metamorphic).
Sedimentary rocks are one of the three different rock types. They are created at or around the surface of the earth. Sedimentary rock is made of sediments which are particles that can be carried through liquid flows. They are the most common rock on land. Around 70-80% of rocks on land are sedimentary. Common types are Limestone, Shale, and Conglomerate. Sedimentary rocks are made from sediments that compact and turn into rock during lithifiction caused by overburden pressure.
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.

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 kind.
