why does the western coast have a lot of harbours while the eastern coast. has a lot of large deltas?
Answers
1) West coast is coast of submergence( except Malabar coast) while east coast is an emergent coast. The continental shelf of east coast extends till 500km into sea.
These imply that sea is deeper in west coast than sea on east coast. So, west coast has favourable conditions for natural harbours.
2) Trade winds play a crucial role in sea travel. During south west monsoon season, these winds help ships to reach India and return during north east monsoon season.
3) India's involvement in a huge trade with Africa, Europe(construction of Suez canal) and central Asia.
4) British rule might have also favoured ports on west coast as it is easier and faster to transport raw materials to England.
5) India is famous for its cotton from ancient times. Cotton mills are mainly located in Ahmedabad and Mumbai.
