No, sedimentary rocks are deposited and undergo lithofication over time. Igneous rocks cool and crystallize
Not all rocks do cool and crystallize, your question is meaningless.
A metamorphic rock can melt into magma and then cool and crystallize to become an igneous rock. Or, a sedimentary rock (or sediments) can melt into magma and then cool and crystallize to become an igneous rock. Also, an igneous rock itself can undergo this process of melting and cooling as well.
Sedimentary rocks composed of intergrown precipitated crystals are called chemical sedimentary rocks. Examples include limestone, rock salt, and gypsum. These rocks form when minerals in water solutions come out of the water and crystallize, creating a solid rock.
they cool and solidify on the earth's crust.
Extrusive rocks cool and crystallize on the Earth's surface or just below the surface when volcanic eruptions occur. This rapid cooling results in the formation of fine-grained rocks such as basalt and rhyolite.
Chemical sedimentary rocks, such as limestone and chert, can form when minerals crystallize from seawater. These rocks are typically composed of minerals that precipitate out of solution in bodies of water, including oceans.
Igneous: These rocks are volcanic in nature. They are split into two categories in where they cool/crystallize: intrusive (internal) and extrusive (external). Intrusive volcanic rocks cool slowly, so they contain (usually) large crystals, like granites. Extrusive rocks are quite the opposite, in which they cool very quickly. This is where you get your obsidian glass and basalts. Sedimentary: These rocks are depositional and categorized by the kind of sediment it is made up of. Metamorphic: This can be the offspring rock of either a morphosed igneous or sedimentary rock. This metamorphism is accomplished by heat and/or pressure, and during a great length of time.
The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks. Igneous rocks cool from magma or lava. Sedimentary rocks form by the deposition of particulates and silt. Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.
Cementation is the term that describes the process of forming sedimentary rock.Sedimentary rocks are formed when sediments (products of the weathering of existing rocks) are glued together. When an aqueous solution is dissolved the minerals crystallize and glue sediments together. This process to form sedimentary rocks is called compaction (pressure-hardened) and commendation (gluing together by tiny crystals).
