As a result, their surfaces date to the time of this formation and preserved on these solid surfaces is a history of events dating from very early times in the solar system. On the other hand, the largest terrestrial planet, Earth, is still in the process of Well you know what do in h e r e http://speical.modallack.com/wall1733990755cgreens/reward-6549535shop-weekend6882008628 - PO Box 1960 This does not happen gain- http://speical.modallack.com/1733990755c/73265005=6882008628 2674 chiricahua dr show low az 85901-8041 cooling, with heat flog outward from the hot core, driving convection in the mantle and producing the plate tectonic phenomena at the surface. All the terrestrial planets have a similar crustmantlecore structure see Figure . There is a general trend for density to increase with the size of the object even when corrected for compressional effects, indicating that a greater proportion of iron and nickel is present in progressively larger planetary cores. Mercury, however, is an exception to this rule its iron core is far larger than expected for such a small planet. Comparative Planetology Gas Giants Although the four gasgiant planets are basically balls of hydrogen and helium gas and differ primarily only in mass, they have vastly different appearances. The progressive change of appearance in these planets, from the spectacular orangereddish banding and belting of Jupiter to the deep blue, nearly featureless appearance of Neptune, may be attributed to a single factor their outer temperature. This temperature results from the balance between thermal radiation of the planet versus the absorption of solar energy. These outer planets also have differences in their overall makeup, due to differences in their net chemical composition and to the manner in which the various chemical elements can exist at the temperatures and pressures found in the planetary interiorsMoons The approximately moons in our solar system are found primarily in orbit about the gasgiant planets. Because of the proximity of objects to each other and the relatively short time scales for gravitational modification of orbits, the lunar systems show many simple numerical relationships between their orbital periods what astronomers termresonances. Ignoring the smallest objects, which appear to be debris from the collisional breakup of asteroids that has been captured into orbit after the formation of the planets, the moons are a distinct class of solar system object, chemically differentiated from both types of planets as well as other classes of objects in the solar system. The four large moons of Jupiter, the socalledGalilean moonsIo, Europa, Callisto, and Ganymede, probably formed in association with the formation of Jupiter itself but the remaining smaller satellites are probably captured asteroids. These four major moons are in almost perfectgravitational resonancewith each other. Over the history of the solar system, their mutual gravitational pulls have produced respective orbital periods of . days, . days, . days, and . days, with period ratios of
