Fragments of a rock unit (xenolith meaning foreign rock) which are included in another (host) rock unit must be older than the host rock. This may occur in sedimentary environments, where pieces of pre-existing rock can be ripped up and included in younger sediments. Alternatively, when igneous rocks are intruded, fragments of the country rock may be incorporated into the intrustion.*

The science that deals with Earth's history of rocks is called geology. There are geologists that study rocks for a living.
The scientific study or rocks and rock forming minerals is known as petrology. It is a sub branch of geology.
Rocks are studied in the scientific discipline of geology.
The study of rocks is is called geology but a person who study's them is called a petrologist
Lithology

Rocks are related to math because of geology and in geology you use math.
