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 Explanation
Sedimentary 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 conglomerate
- There 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 rocks
Metamorphic rocks
- These 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 gneiss
Igneous 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.
