Here's why:

* Igneous rocks are formed from the cooling and solidification of magma or lava.

* Sedimentary rocks are formed from the accumulation and cementation of sediments.

* Metamorphic rocks are formed when existing rocks (igneous, sedimentary, or even other metamorphic rocks) are transformed by heat, pressure, or chemical reactions.

Soapstone is a metamorphic rock derived from talc-rich rocks like serpentine or dolomite. The intense heat and pressure during the metamorphic process transform the original minerals into talc, giving soapstone its characteristic soft, smooth texture and ability to be easily carved.
