Which is not a process involved in the formation of sedimentary rock? compaction deposition extrusion weathering

Extrusion is not a process involved in the formation of sedimentary rock

Extrusion is NOT a process involved in the formation of sedimentary rock.

Further ExplanationSedimentary rocks Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. These sediments includes; pebbles, shells, sand and other material fragments.  The sediments accumulates in layers and then harden into rocks over a period of time.Examples of sedimentary rocks include; limestone and conglomerateThere are five basic steps involved in the formation of sedimentary rocks: Weathering (making the sediment by breaking down or dissolving preexisting rocks or living organisms)Erosion (picking up the sediment by water, wind, or glaciers)Transportation (moving the sediment by water, wind, or glaciers)Deposition (depositing the sediment)Lithification (turning the sediment to rock).Other types of rocksMetamorphic rocksThese are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.Examples of metamorphic rocks are marble and gneissIgneous rocks These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.Examples of igneous rocks include obsidian and basalt.The three types of rocks may be further classified in terms of chemical composition, texture and formation.
