Oceanographers study a wide range of topics such as plate tectonics to ocean currents to marine organisms. Branches are of four sorts: Biological oceanography, Chemical oceanography, Geological oceanography, Physical oceanography.

A coastal zone is a place where the land and water interfaces with each other. The Coastal Zones play an important role in the human survival because many people will occupy the coastal areas. Due to the interactions between the land and the water there are lot many changes occurred in the coastal zones. 70% of the Earth’s surface is covered with water so we can say that the marine ecosystem is the largest Ecosystem, where more than 90% of the Marine Ecosystem is covered by the marine environment.
