Lithosphere (Rocks)

The lithosphere (rocks) is one of the four primary components of the Earth’s spheres: the atmosphere (air), biosphere (life), hydrosphere (water), and lithosphere (rocks). In competitive examinations, examiners frequently assess candidates’ knowledge of geology, where the lithosphere constitutes one of the fundamental topics. It has been observed that geology-related questions—particularly those concerning the lithosphere—are commonly asked in exams conducted by FPSC, SPSC, BPSC, KPPSC, PTS, OTS, STS, NTS, and even UPSC. In light of this, our team has compiled a comprehensive set of multiple-choice questions (MCQs) on the lithosphere to assist our users in their exam preparation.
