BGYET-147 IGNOU Handwritten Assignment 2026-27

Course Scope and Syllabus Overview for BGYET-147: Geomorphology and Geotectonics

BGYET-147: Geomorphology and Geotectonics is a core course under IGNOU’s Bachelor of Science (BSCG) programme, designed to explore the dynamic processes shaping Earth’s surface and the underlying tectonic forces driving geological evolution. This course integrates field-based observations with theoretical frameworks to analyze landform development, tectonic plate interactions, and the interplay between geological structures and environmental systems. Students gain a rigorous understanding of erosional agents, depositional patterns, and the mechanics of continental drift, equipping them with analytical skills to interpret geological landscapes and tectonic histories. The syllabus aligns with IGNOU’s CBCS structure, emphasizing both conceptual clarity and practical application through case studies and regional examples. It bridges foundational principles with advanced topics, ensuring students can critically evaluate geomorphic processes and tectonic theories while preparing for field-based assessments.

Key Syllabus Units and Topics

• Block-1: Basic Concepts of Geomorphology: Covers the definition and scope of geomorphology, including the study of landform genesis, classification systems, and the role of climate, lithology, and time in shaping surfaces. Key theories like Davisian cycles and Penck’s stage theory are analyzed for their explanatory power.
• Block-2: Landforms: Examines fluvial, glacial, aeolian, and karst landforms, detailing their formation mechanisms, spatial distributions, and evolutionary models. Emphasis is placed on tropical and temperate landform assemblages, including river terraces and coastal features.
• Block-3: Fundamentals of Geotectonics: Introduces plate tectonics, orogenic belts, and the stress-strain relationships governing mountain building. Students explore the Wilson Cycle and the role of mantle convection in driving continental rifting and collision.
• Block-4: Plate Tectonics and Movements: Focuses on the kinematics of plate boundaries (divergent, convergent, transform), hotspot volcanism, and the geological evidence supporting plate reconstructions. Regional case studies, such as the Himalayan orogenic wedge, are dissected for tectonic interpretations.

Frequently Asked Questions

Q: What is the marking scheme for the BGYET-147 assignment, and how many marks are allocated to each question?
A: The BGYET-147 assignment carries 30 marks, with each question typically allocated 5–10 marks based on complexity. The IGNOU evaluation criteria prioritize clarity, depth of analysis, and adherence to geological principles, so structured answers with field examples are strongly recommended.

Q: Are there any specific pass marks or criteria for the BGYET-147 course, including both theory and practical components?
A: To pass BGYET-147, students must achieve a minimum of 40% in the theory examination (100 marks) and 40% in the combined assignment and practical (if applicable). The assignment alone contributes 30% of the total course grade, underscoring its importance in overall assessment.
