Main Body
Continental Drift Theory was proposed by Wegener. to explain how palaeo-climate varied between disparate continents
Essl Basis Principle:
~ Earth consist of upper SIAL layer, which floats over lower SIMA layer. This is because SIAL is less dense than SIMA.
Force Responsible:
1Gravitational force - causing North and Southward movement due to differentiated axe
2Eaths rotation caused East West movement
1Coral also cannot survive in high salinity conditions.
2Salinity determines density - which affects the ease of navigation for ships, as per Archimedes' principle
3High saline water is much expensive to desalinize for drinking purposes.
4Increased salinity destroy coastal biodiversity ecosystem such as mangroves & delta etc
The salinity is a salient feature of ocean which affect both marine and human life.
