FAQs on IIT JAM GEOLOGY - GG - Free coaching Lecture 17 - Coastal Geomorphology (Part I); In English

1. What is coastal geomorphology?
Ans. Coastal geomorphology is the study of landforms along coastlines and the processes that shape them. It examines the interaction between geological, oceanographic, and atmospheric forces in creating features such as beaches, cliffs, and estuaries.
2. What are the main processes involved in coastal erosion?
Ans. The main processes of coastal erosion include wave action, tidal forces, and currents. These forces can remove material from the shore, causing the coastline to recede. Factors such as storm surges and human activities further influence the rate and extent of erosion.
3. How do human activities impact coastal geomorphology?
Ans. Human activities such as construction, dredging, and the building of coastal defences can significantly alter coastal geomorphology. These actions can disrupt natural processes, leading to increased erosion, habitat loss, and changes in sediment transport dynamics along the coast.
4. What role do tides play in shaping coastal landforms?
Ans. Tides, caused by the gravitational pull of the moon and sun, play a crucial role in shaping coastal landforms. They influence sediment deposition and erosion patterns, affecting the formation of features like tidal flats, salt marshes, and mangroves.
5. What are some common coastal landforms and their characteristics?
Ans. Common coastal landforms include beaches, which are typically sandy or pebbly areas formed by the accumulation of sediment; cliffs, which are steep rock formations created by erosion; and estuaries, which are transitional zones where freshwater meets saltwater, characterised by diverse ecosystems and dynamic sedimentation processes.
