E. Oceanography
Oceanography is a scientific discipline concerned with all aspects of the world’s oceans and seas, including their physical and chemical properties, their origin and geologic framework, and the life forms that inhabit the marine environment.
In Oceanography, we learn about Hydrological cycles, Currents, waves, tides, marine life such as coral life, major and minor relief features, etc.
Ocean Currents :
Ocean currents are large, continuous movements of seawater that flow through the world’s oceans. They are driven by factors such as wind, the Earth’s rotation, temperature differences, and salinity levels. Notably, ocean currents play a critical role in regulating Earth’s climate by transporting heat around the globe.
