3.2. Mapping of Ocean Floor

Post-war period saw surge in the detailed research of the ocean configuration. It revealed that ocean floor is not just a vast plain but is full of features such as mid-oceanic ridge, trenches, Abyssal plains etc. The mid-oceanic ridges were found to be most active in terms of volcanic eruptions. The age of rocks from Oceanic floor is nowhere more than 200 million years as compared to billions of year sold rocks from continental region and hence, oceanic rocks are much younger than the continental areas. Another interesting fact was that the rocks located equi-distant from the crest were found to have remarkable similarities in terms of their constituents, age, magnetic properties etc.
