GEOLOGY

Detailed explanation-1: -Petrology is the study of rocks-igneous, metamorphic, and sedimentary-and the processes that form and transform them.

Detailed explanation-2: -What Does a Petrologist Do? Petrologists find certain types of rocks and analyze them in a lab, determining their exact composition and how to best extract valuable minerals and natural resources from them.

Detailed explanation-3: -Petrology (from Ancient Greek (pétros) ‘rock’, and- (-logía) ‘study of’) is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology.

Detailed explanation-4: -Petrography is the study of rocks in thin section by means of a petrographic microscope (i.e., an instrument that employs polarized light that vibrates in a single plane). Petrography is primarily concerned with the systematic classification and precise description of rocks.
