Surface composition Io's colorful appearance is the result of materials deposited by its extensive volcanism, including silicates (such as orthopyroxene ), sulfur , and sulfur dioxide . When the Moon was relatively young, its interior was still molten. This video will tell about Moon surface composition Moon geology Orbital distance Moon radius Lunar eclipse. The Moon resembles the terrestrial planets in composition, but most of the other moons—which orbit the giant planets—have larger quantities of frozen ice within them. In general, worlds closer to the Sun have higher surface temperatures. Apollo Data Revealed Moon's Internal Structure NASA deployed the frist seismographs on the moon as part of the Apollo Mission in 1969. Consequently, magma sometimes rose and erupted onto the surface. Much of this dust has fallen to the moon from the spaces between the planets over the last several billions years. The Moon is essentially "dead" geologically with little tectonic activity. There are three distinct layers of the moon namely the crust, the mantle, and the lunar core. The lunar core has far less iron, and there are no molten components. Crust. Lunar day: 29.5 Earth days (the moon is tidally locked to the Earth, so our gravity drags the moon around on its axis and the same side of the moon always faces Earth)

The surface of the moon has about two inches of dust. You can see this in some pictures taken by the astronauts of their footprints on the moon. Because the bottoms of impact basins were often the lowest places on the surface of the Moon, the erupting lava would flow into them and begin to fill them. The crust is the outermost layer of the moon and it consists of a dusty outer rock layer which is known as the regolith. Mean surface temperature: sunlight = 266 F (130 C), ­shadow = -292 F (-180 C) Atmosphere: None. In the past, the South Pole-Aitken crater has garnered plenty of interest both for its surface composition and its size. Finally, there is no life on the Moon. What is the surface of the moon like? Orbital period: 29.5 day. Gillis and colleagues' ground-truth-calibrated abundances of Th, K, and FeO provide researchers a better look at the Moon's crust, which bears on all studies of the Moon's origin, crustal formation, and bulk composition. Future missions will enhance our knowledge of the chemical composition of the lunar surface. Just like the earth, the moon has layers. Gary Lofgren has a related idea: "The gases 'evaporating' from the moondust might come from the solar wind." The surface of the Moon changes slowly, because none of these factors are active. Huge mystery blob found under the moon's far side.

It probably feels pretty soft. Unlike Earth, he explains, the moon is exposed to the hot wind of hydrogen, helium and other ions blowing away from the sun. The Moon has a core, mantle, and crust, just as the Earth does, but the composition of the core is different.

Layers of the Moon. Above: The moon--a 4 billion year old desert. Without an internal heat source, the Moon is geologically dead, and so too without volcanism or plate tectonic activity. These seismographs collected data and enabled researchers to determine that the moon's structure consisted of a thin crust of about 65 kilometers, a mantle about 100 kilometers thick and a core with a radius of about 500 kilometers. The Moon lacks an atmosphere, and the small amount of water that is present is "buried" in the polar areas.
