Large and small asteroids continued to pelt the surface, but at a slower pace, leading to overlapping craters and craters on top of lava flows.The crust of the moon is made up of a rocky surface covered with regolith. The Moon formed about the same time as Earth, but could have been made during a collision event, rather than co-formed with Earth. The regolith on the surface can be as shallow as 10 feet (3 meters) in the maria or as deep as 66 feet (20 meters) in the highlands.Like the Earth, the moon boasts a crust, mantle and core. Based on what we know about how planets and moons form, the core of the moon is believed to be at least partly molten and likely consists primarily of The largest portion of the Earth's moon is the mantle.

Deep inside of its interior, the moon may have a solid iron core surrounded by a softer, somewhat molten liquid iron outer core. NY 10036. The Sun and planets formed in a cloud of gas and dust called a protoplanetary disk some 4.5 billion years ago. The outer core may extend as far out as 310 miles (500 km). The crust consists of 43% oxygen, 20% silicon, 19% Although it is very thin, the moon does have an atmosphere. The Moon is an astronomical body orbiting Earth as its only natural satellite. The composition is not well known, but it is estimated to consist of helium, neon, hydrogen (H2), argon, neon, methane, ammonia, and carbon dioxide, with trace …
People have wondered about the dark and light spots on the surface throughout history. However, over time, the magma cooled and solidified, thus ending volcanism on the moon.Get breaking space news and the latest updates on rocket launches, skywatching events and more!Thank you for signing up to Space. Scientists have samples from the surface, or crust, of the moon, but the composition of the inner layers is a mystery. © The composition of the two bodies is similar, which is part of why scientists think the moon may have formed from a large meteor impact breaking off a piece of the Earth while it was still forming. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. It is the fifth-largest satellite in the Solar System, and by far the largest among planetary satellites relative to the size of the planet that it orbits (its primary). New York, The composition is not well known, but it is estimated to consist of helium, neon, hydrogen (HIf you're interested in learning more about the moon and its composition, NASA's moon On Earth, plate tectonics and erosion covered up much of the evidence from this period, while the Of course, the period of heavy bombardment, which ended about 3.8 billion years ago, wasn't responsible for all of the craters on the moon. The crust of the Moon is composed mostly of oxygen, silicon, magnesium, iron, calcium, and aluminum.
The moon is the easiest body in the solar system to observe with the naked eye. The Moon is, after Jupiter's satellite Io, the second-densest satellite in the Solar System among those whose densities are known. Early in the solar system's history, all of the planets and moons suffered through a period of heavy bombardment, as the last of the large rocks were captured by their gravity and crashed into their surface. This is the layer between the crust (the part we see) and the inner core.
The moon's surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer.Early scientists thought the dark stretches of the moon might be oceans, and so named such features The moon's surface shows plenty of evidence of asteroids.
