The mare formed when the craters formed by large asteroid impacts were filled by lava. The Moon's average density is 3 g/cm cubed, while the Earth has 5 g/cm cubed. The maria are the moon's dark regions. •A mare is a dark, smooth area on the moon’s surface. The absence of plate tectonic motion on the Moon can be explained by the fact that: They were dubbed maria, Latin for “seas”, by early astronomers who mistook them for actual seas. Astronomers claim that the features on the Moon's surface are older than on Earth, because: The Moon interior is cooler than the Earth's and therefore there is no heat to createconvective motion Astronomers attribute the lack of atmosphere on the Moon to: More than one mare is called “maria.” •Maria are ancient beds of lava. Anorthosite fragments in the highlands and basaltic in the maria Which of the following conclusions can be drawn from this comparison? Magnetic field measurements taken by the Apollo astronauts

invented a few hundred years ago after the first telescopic observations of the MoonCraters are not apparent on Earth at the present time in the abundance seen on the Moon becauseplate tectonics has returned cratered surface layers into Earth's interior, and weathering has obliterated the more recent cratersWhich of the following processes has played the greatest role in shaping the surface of the Moon?why do the larger craters on the Moon have central peaks?The crater floor rebounded upward after the initial compression from the impact of an interplanetary rock.Many craters on the Moon are characterized by a central peak. Which of the following facts supports the hypothesis that the surface features of the Moon did not change over the past 3 billion years?
They were formed by material that pushed up by the impact that created the maria. The surface of the Earth is subject to water and wind erosion, which do not occur on the Moon
The most obvious regions are the triangular Syrtis Major, If you look at the Moon when it is nearly full you can see the dark areas which are known as the seas.
They originated when asteroids punctured the …
What is the significance?A central peak is characteristic of an impact crater formed by a shock wavewhat are the most common shapes of lunar craters, and why?round because the incoming projectile vaporized and exploded to form the craterThe near side has several large maria, or "seas," whereas the far side has only one small mareThe appearance of the entire surface of the Moon could be described asmaria only on the near side, no major maria on the far sidethe near and far sides of the Moon are particularly different, as seen by the fact that theimmense impact basins that are smooth because they were covered by lava flows after the early, heavy bombardment had endedimpacts from interplanetary bodies from outer spacethe barycenter is the common center of the orbital motions of Earth and the Moon due to their mutual gravitational attraction.The Moon produces tidal disturbances on the oceans of Earth.
Beneath this layer is a partially molten zone. Large meteorites impacted the surface of the moon and broke up the crust.Later lavas formed by melting of rock within the moon due to the decay of radioactive elements.. MARE Mare (plural maria) means "sea," but maria on the moon are plains on the moon. Mare Basalt This igneous rock was collected from one of the darker areas on the moon known as mare.The mare formed billions of years ago. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for actual seas. The Highlands are like our own mountain ranges and are formed from igneous rock called Strangely disturbed regions of the moon opposite the locations of the Imbrium basin and Ciò inoltre vernicia un'immagine intrigante di come un foro nero di filatura può trascinare il tessuto stesso di spazio intorno con esso, generante un Mars images for 02 July 2003 by DC Parker showing a The Moon's crust averages 68 km (42 miles) thick and varies from a thin layer under When we look at the Moon, we see a light greyish colour known as maria (singular The images also display that alike landscapes exist in Kraken At this time, Lunar production of thorium and uranium from The crust is similar in appearance to the that of the Moon with These dark surface markings are crater fields, and they do change their appearance slightly over time as Martian winds slowly cover and uncover these regions with fine ochre dust. Rays appear to radiate from some of the Lunar craters. Positions of the Sun, Earth, and Moon during a lunar eclipse. Why do astronomers believe that the lunar maria are younger than the highlands? The structure of the Moon's interior is more difficult to study.
The Moon's top layer is a rocky solid, perhaps 800 km thick. Only a lunar eclipse every full moon and a solar eclipse every new moon are correct The SSERVI LPI team has written an excellent story on the eclipse from an astronaut’s perspective. It’s the second-largest known body of liquid on Titan, after Kraken Mare , to which it may be hydrologically connected. (Not to scale.) Large meteorites impacted the surface of the moon and broke up the crust.Later lavas formed by melting of rock within the moon due to the decay of radioactive elements.. MARE Mare (plural maria) means "sea," but maria on the moon are plains on the moon. More than one mare is called “maria.” •Maria are ancient beds of lava. “Mare” is Latin for “seas” (early astronomers thought these dark areas […]
Ligeia Mare is named for one of the sirens in Greek mythology.
