Final answer:

The basic classification of rock types is based on their origin: igneous, sedimentary, and metamorphic. Igneous rocks form from cooling magma or lava, sedimentary rocks form from accumulated sediment, and metamorphic rocks are formed through the alteration of pre-existing rocks by heat and pressure.

Step-by-step explanation:

The basic classification of rock types is based on their origin. Rocks are classified into three main types: igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed from the accumulation and cementation of sediment, while metamorphic rocks are formed through the alteration of pre-existing rocks by heat and pressure.
