As we know, our earth's crust is comprised of the lithosphere( continental plate) and oceanic plate.
The following are the difference between the oceanic and continental plates:
- The oceanic plate is made up of heavier material-dominated basalt rocks and Gabro rock( iron and magnesium) as compared to the lithosphere plate dominated by granite rocks( Silicon, Alumunium).
- The oceanic plate is much thinner than the continental plate.
- The oceanic plate is much younger(less than 200 million years) than the continental plate ( more than 1 billion years).
- The oceanic plate is made up of divergent boundaries; upwelling magma from the mid-oceanic ridge and it subducts near continents.
What is Oceanography?
In Oceanography we study the physical and biological components of the ocean including ocean waves and current. The following study includes,
- Configuration of ocean
- Botton topography of the ocean
- Different Marine landsforms
- Marine resources
- Temperature, salinity, wave, tidal wave
- Wave energy
- Marine pollution
What is oceanology?
The scientific study of all components of the ocean including the cause and consequence of these components is called oceanology.
