Expert Solution

Step 1

Oceanography is the field of science which deals with studying the geology of oceans and sea, their physical and chemical properties. Oceanography also includes ecosystem dynamics like plate tectonics, geophysical fluid dynamics, waves , ocean currents etc. Study of oceans are important to understand shift in earth energy balance, along with related changes in global and regional climate. Study of climatology helps researches, scholars and climatologist to understand about the ocean salinity, temperature and other aspects.
