NCERT SOLUTIONS

*Q1. How do different features of the ocean floor affect human activities such as fishing, transport, and underwater exploration?*


*Ans. Ocean Floor & Human Activities:*

- *Fishing:* Continental shelf is shallow, gets sunlight, has more plankton and fish - Best fishing ground. Seamounts also attract fish.

- *Transport & Trade:* Abyssal plains are flat - Easy to lay submarine cables, pipelines. Continental shelf used for ports and harbours. Ships avoid trenches and ridges.

- *Underwater Exploration & Mining:* Continental shelf has oil, gas, minerals. Trenches and ridges help scientists study earthquakes, plate tectonics. Seamounts studied for biodiversity.


*Q2. How do waves, tides, and ocean currents influence climate, marine life, and human activities?*


*Ans.*

- *Waves:* Called coastal architects - Make caves, arches, beaches by erosion. Carry energy. During storm cause coastal damage.

- *Tides:*

  a) Navigation - High tide helps big ships enter harbour - Eg. Gulf of Khambhat has 12m tide.

  b) Fishing - Fish come to shore in high tide - Better catch.

  c) Energy - Tidal energy in Gulf of Kutch, Khambhat, Sundarbans.

- *Currents:*

  a) Climate - Warm Gulf Stream keeps Norway warm, cold Labrador makes ice.

  b) Marine Life - Meeting of warm + cold = best fishing grounds - nutrients.

  c) Human Activity - Affects shipping routes, fishing zones.


*Q3. Describe the importance of marine resources.*


*Ans. Importance of Marine Resources:*

- *Food & Livelihood:* Fish is protein source, fishing gives jobs to millions in India.

- *Energy & Minerals:* Oil, natural gas, tidal energy, wave energy, sand, manganese nodules.
