JNTU B.Tech III ENGINEERING GEOLOGY Previous Question Paper (May - 2018 - R13)
Part A is compulsory. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit.
Part A
Write briefly about structural geology.
Answer
Structural geology is the study of the arrangement, deformation, and architecture of rock bodies in the Earth's crust. It focuses on identifying and analyzing structures such as folds, faults, joints, and foliations to understand the tectonic forces that shaped the Earth's surface.
Write short notes on geological agents.
Answer
Geological agents are the natural forces responsible for the continuous modification of the Earth's surface through processes of weathering, erosion, transportation, and deposition. These agents are categorized into exogenic (external), such as wind, water, ice (glaciers), and waves, and endogenic (internal), such as volcanism and tectonic movements.
