FAQs on Action of Waves - Indian Geography, UPSC IAS Exam Preparation Video Lecture - Geography (Prelims) by Valor Academy

1. What is the action of waves in Indian geography?
Ans. The action of waves in Indian geography refers to the movement and interaction of waves in the Indian Ocean and other bodies of water surrounding the Indian subcontinent. These waves play a significant role in shaping the coastal landforms, erosion, and deposition processes along the Indian coastline.
2. How do waves influence the geography of India?
Ans. Waves influence the geography of India by continuously shaping the coastal landforms. The erosive power of waves leads to the creation of features like cliffs, headlands, and sea caves, while the deposition of sediments forms beaches, spits, and sandbars. These coastal landforms provide habitats for various marine species and contribute to the biodiversity of the region.
3. What are the different types of waves found in the Indian Ocean?
Ans. The Indian Ocean is home to various types of waves, including wind waves, tidal waves, storm surges, and tsunamis. Wind waves are the most common type and are created by the transfer of energy from the wind to the water surface. Tidal waves are caused by the gravitational pull of the moon and the sun, while storm surges are large-scale waves generated by severe storms. Tsunamis, on the other hand, are seismic sea waves triggered by underwater earthquakes or volcanic eruptions.
4. How do waves impact coastal communities in India?
Ans. Waves have both positive and negative impacts on coastal communities in India. On one hand, they support fishing and tourism industries, providing livelihood opportunities to local communities. On the other hand, coastal erosion and flooding caused by powerful waves can pose threats to human settlements and infrastructure. It is important for coastal communities to be prepared and have appropriate coastal management strategies to mitigate these risks.
5. What measures are taken to manage the impact of waves in Indian coastal areas?
Ans. To manage the impact of waves in Indian coastal areas, various measures are taken. These include the construction of coastal protection structures such as seawalls, breakwaters, and groynes to prevent erosion and flooding. Beach nourishment projects are also undertaken to replenish eroded beaches with sediment. Additionally, coastal zoning regulations and early warning systems for tsunamis are implemented to ensure the safety and sustainable development of coastal areas.
