I do not know what geologists expect given that the only possible solution for symmetrical generation of crust off the entire length of the Mid Atlantic ridge must include a rotational solution and the lag/ advance mechanism of rotational shear bands can do just that.Other than go to Greenland and die of hypothermia,I do not know what these guys are waiting for given the topography of the oceanic crust indicating rotational signatures either by the MAR or the fracture zones with plenty of room for healthy speculation based on,get this - the Earth rotation may have something to do with geodynamics - http://www.esa.int/esaEO/SEMNBNKIWZF_index_0.html Isn't that equatorial fracture zone a beauty ?,maybe somebody with a love of planetary dynamics and geology who might be tempted to consider rotational dynamics as a more suitable mechanism for crustal evolution/motion as opposed to a thermal 'convection cell' mechanism that will not work and which leave no signatures on the surface crust. So Sam,behind the 24 hour value is an amazing amount of productive work to get off the ground so so speak if somebody ever wakes up to planetary dynamics. >   Do some self-education Gerald!

The velocity of a point on the equator with respect to an observer on the moon might be greater that a point near the pole. *But what's important here* is that for an observer in Scotland the velocity of a point on the Congo is almost zero. Probably something like millimeters per year. Any two observer standing on the ground, no matter their positions on the earth, will share almost zero velocity with respect to each other. Further more it doesn't matter what the exact surface figure of the earth is.

At an elevation of 1 km,roughly .6 km below Denver's elevation ,an observer with an unrestricted view can see across a distance of 112 km to the horizon allowing for any minor variations such as refraction ect .This 112 km value represents the equivalent of 1 degree latitude so that the total distance the observer can see across a North/South longitude meridian is 2 degrees of Latitude. http://www.ncgia.ucsb.edu/education/curricula/giscc/units/u014/tables/table02.html At the location of Denver (using a hypothetical 1 km elevation),the rotational speed for 40 degrees lat is 1281 km per hour so that the observer can see a location at the horizon South of his meridian that is rotating at 1297 km per hour and looking North across the same meridian can see a location at the horizon that is rotating at a speed of 1261 km per hour,the reason being that the Earth is a rotating sphere and this is what happens when it is considered in context. The statement 'all motion is relative' was once considered as a horrifying spectacle and the impetus for finding the technical reasoning behind planetary dynamics as I explained earlier in this thread - And wherever anyone would be, he would believe himself to be at the center.Therefore, merge these different imaginative pictures so that the center is the zenith and vice versa. Thereupon you will see-- through the intellect..that the world and its motion and shape cannot be apprehended. For [the world] will appear as a wheel in a wheel and a sphere in a sphere-- having its center and circumference nowhere. . . " Nicolas of Cusa Unlike the fractured crust which is more or less locked together like an ill-fitting jigsaw puzzle,the fluid interior rotates unevenly in differential rotation bands towards the poles hence the signatures of this rotation can be seen in the MAR, the symmetrical generation of crust off either side of the ridge and the spectacular split at the Equator - http://www.sciencemag.org/cgi/content/abstract/146/3640/57 http://www-odp.tamu.edu/publications/207_SR/synth/images/01_f02.jpg To make a long story short,when the GOCE data indicates rotational components to surface geological features,those interpreting the data will be required to take account of different latitudinal speeds between equatorial and polar regions with a maximum equatorial speed of 1669.8 km per hour/15 degrees at the Equator and subsequently turning an entire 40,075 km equatorial circumference in 24 hours. I have no objection to a geostationary mechanism of thermal 'convection cells',they just don't interest me and that is all. Probably something > like millimeters per year.

Don't want to tax your brain too hard, Gerald, but a geosynchronous satellite can "see" Denver and a location on the equator simultaneously and the two locations have NO relative motion. |
