![]() Because of this, the surface of Io experiences a constant state of. Triton may thus preserve the organic chemistry that might have led to the origin of life in early terrestrial hydrothermal systems. A side effect of these tidal forces is heat, which keeps most of Ios crust in liquid form. Nicholson Add to Mendeley Cite (89)90169-3 Get rights and content Abstract Alone of all the major Solar System satellites, Triton may have an obliquity near 100. Depending on the temperature and prevailing oxidation state, acetic acid, ethanol, urea, methanol, and ethanamine are possible important components, in addition to ammonia, of the resulting mantle material. On the obliquity and tidal heating of Triton David G. Although tidal heating is generally associated with spin-locked satellites on eccentric orbits, a satellite with a large obliquity can undergo substantial heating due to obliquity tides, even on a circular orbit. Inward tidal evolution would then have re- sulted in Tritons present obliquity being -100 °. Our calculations also show that whatever the original source of nitrogen in Triton, N2 and/or NH3 are likely abundant products of hydrothermal reprocessing. Tritons spin axis would have been located close to the normal to its invariable plane ( Neptunes orbit plane, at this distance). Today, there is probably not enough tidal heating for a liquid water ocean to exist under Triton. However, Tritons high inclination likely causes a significant (0.7°) obliquity, resulting in large heat fluxes due to tidal dissipation in any subsurface ocean. Such reprocessing could explain the lack of carbon monoxide in the atmosphere of Triton and its depletion relative to N2 and (apparently) CO2 in the satellite's surface ices. As the orbit changed, the tidal forces were reduced. Radiogenic heating is sufficient to maintain a long-lived ocean beneath a conductive ice shell, but insufficient to cause convective deformation and yielding at the surface. B) the volcanos on Io (a moon of Jupiter) C) the rings of Saturn. We assume that the latter would have been controlled by mineral assemblages in the rock. 23) Which of the following is not due to tidal forces A) the synchronous rotation of the Moon around Earth. ![]() We consider the chemical consequences of this hydrothermal reprocessing on Triton's volatile budget by assuming an initial cometary composition for the icy mantle and evaluating the effects of changes in temperature and oxidation state. Past thermal models have typically included only. If that is the case, tidal heating could have melted (as seen in the above image) Triton in its originally eccentric orbit, and the satellite might even. ![]() This heating would have driven hydrothermal circulation at the core-rock/mantle-ocean boundary. Librations can strongly affect the tidal heating budget of a moon (e.g., Rhoden & Walker 2022). ![]() Subsequent to its capture by Neptune, Triton could have experienced an episode of tidal heating sufficient to melt its icy mantle and possibly its rocky core as well. ![]()
