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.
In earth
There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
there are 3 types of rocks- Igneous Rocks, Sedimentary Rocks, and Metamorphic RocksThere are three main type of rocks in the world. The names are Igneous, Sedimentary, and Metamorphic.The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary.
Igneous, metamorphic, and sedimentary are the three types of rocks. Sedimentary is formed when layer of mud or silt build up gradually. Igneous is formed when molten magma cools. Metamorphic is formed when a type of rock changes to another type
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
manhattan was formed from three diffrent types of rocks :)
There are three main types of rocks: igneous, sedimentary, and composites. Igneous rocks are formed when sedimentary or composite rocks experience extremes of heat and pressure. Sedimentary rocks are formed when smaller particles are overlaid for extended periods of time. Composite rocks are formed a mixture of elements under pressure.

There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
Metamorphic rocks are formed from an existing rock (of any of the three types) being subjected to a combination of heat and pressure.

the three major rocks are igneous, sedimentary, and metamorphic rock. igneous- volcanic rocks sedimentary- rocks with layers on top metamorphic- rocks that formed to another rock
Igneous, metamorphic, and sedimentary are the three types of rocks. Sedimentary is formed when layer of mud or silt build up gradually. Igneous is formed when molten magma cools. Metamorphic is formed when a type of rock changes to another type
igneous rocks are formed by cooling lava from volcanos. Obsidian is an igneous rock. Sedimentary rocks are formed by particles being deposited by water. Sandstone is a sedimentary rock. Metamorphic rocks are formed when heat, pressure, and chemical reactions change existing rocks. Granite is a metamorphic rock.
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
the three types of rocks are classifed based on theire mode of formation or occurence where, they are formed but not of the todays occurence.
