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.
It shows that the three forms of rocks are interelated to one another and each leads to the other.
The term lava can still be used to describe a lava flow after it has solidified on the earth's surface. It forms igneous rock, one of the three main rock types on Earth.
the three types of land forms are the mountains, plains, and plateaus
There is no last rock, because the process of the formation of the three rock types is continuous.
Three types of igneous rocks are pumice, basalt, and granite.

There are three types of rocks! These include: -Metamorphic -sedimentary -igneous
The types of rocks which are found in Australia are various forms of metamorphic, igneous and sedimentary, the three rock classifications.
The three main types of stress in a rock are shearing, tension, and compression.

When lava cools it forms extrusive igneous rock.
The term lava can still be used to describe a lava flow after it has solidified on the earth's surface. It forms igneous rock, one of the three main rock types on Earth.
All three rock types, sedimentary, igneous, and metamorphic, are composed of minerals.
