Planetary Astrophysics - Problem Set 11Sea Level[10 points] The average depth of the Earth's oceans is abouth= 4 km.How muchdenser is the water at the bottom of the ocean compared to the top? Neglect variationsin salinity and temperature. ESTIMATE the fractional density difference, ??/?. Usea bulk modulus for water ofM=?(?P/??) = 0.02 Mbar.By "ESTIMATE", wemean that answers that match ours to within a factor of 3, and that have the correctreasoning, receive full credit.If this density contrast ??/?were to (magically) disappear (i.e. if the water at thebottom of the ocean were to become less dense), by ABOUT how much would sea levelrise?
