Basics indeed! |
John, about every other note that I post here gets attacked in one way or another by one person or another. And in a way that includes you. The science that I am discussing is both perfectly reasonable and understandable for anyone with a moderately good background in science who is willing to invest a little time in trying understand it. You are probably regarded as something of an authority on earthquakes. And you keep saying that the information that I am posting here is bad science. I feel that you are wrong about that and consider that criticism to be something of an unjustified attack. Many of the people with whom I communicate are in positions where they can be affected by politics in their countries. And I am not going to say whom they are and let them get attacked by people posting notes here or in the Newsgroups just because they are talking with me!
I checked the PREM table which I am guessing you were referring to. And if I correctly understood what the symbols stand for then the data were just what I expected, in fact even better than I expected: http://solid_earth.ou.edu/prem.html The core has a density of 13088 kg/m3 out to a radius of about 1221 km compared with 2600 kg/m3 for the crust at a radius of 6368 km.So, my air – water – stone in the balloon example is accurate as that table shows. The core is like the large stone in the balloon with a density difference of roughly a factor of 5 over outer Earth layer material. Ocean tides have relatively little importance for the calculations I am presently doing. Besides, how could they be affecting earthquakes occurring in Afghanistan and Turkey? These are personal opinion.
