     Most common rocks exposed on Earth’s surface

     • Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks. Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.

   What are sedimentary rocks?

   • Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

   How are sedimentary rocks formed?

   • They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes. An example of a sedimentary rock, which is, by definition, composed of many, smaller rocks. Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth.

   Are sedimentary rocks confined to Earth's crust?

   • Sediments and sedimentary rocks are confined to Earth’s crust, which is the thin, light outer solid skin of Earth ranging in thickness from 40–100 kilometres (25 to 62 miles) in the continental blocks to 4–10 kilometres in the ocean basins. Igneous and metamorphic rocks constitute the bulk of the crust.

   What determines the type of sedimentary rock that will form?

   • The environment where the sediments are deposited determines the type of sedimentary rock that will form there. Sediments accumulate and over time may be hardened into rock. Lithification is the hardening of layers of loose sediment into rock (Figure 4.12). Lithification is made up of two processes: cementation and compaction.
