Title: Compare and contrast ocean basins and continents. Post by: barry on Aug 30, 2013 Compare and contrast ocean basins and continents.
Title: Re: Compare and contrast ocean basins and continents. Post by: irina on Aug 31, 2013 One significant difference between these is their respective elevations. Ocean basins are lower in elevation whereas continents are higher in elevation. However, his elevation difference is the result of different material densities and thicknesses. Continental material is thicker (up to 70 km), but in spite of that sits higher on the mantle because it is less dense (2.7 g/cm3). Oceanic material is thinner (averaging at 7 km), but denser (3.0 g/cm3).
